H-TCP congestion control algorithms
2016-09-27 22:18:27 -07:00
- (internet) Add a TOS field to the InetSocketAddress class
2016-06-02 01:16:39 +02:00

ns-3 spectrum framework, has been introduced. The current version of
this model matches the API and behavior of YansWifiPhy closely, but
over time is expected to support a different PHY abstraction and error
models.

New user-visible features
-------------------------
2019-07-02 16:21:21 +02:00
- (internet) The native TCP implementation has been refactored, for the
following improvements:
1) congestion control has been aligned with the Linux architecture,
2016-03-12 17:37:01 -08:00
to facilitate easier coding of new congestion control algorithms
2019-07-02 16:21:21 +02:00
or porting implementations from the Linux kernel,
2) Fast Retransmit and Fast Recovery algorithms, compliant to RFCs, are
shared by all TCP variants, unlike previous releases.
2016-03-12 17:37:01 -08:00
3) TCP Hybla and TCP HighSpeed variants have been added.
- (routing) The PrintRoutingTable* functions now print the following information
2019-07-02 16:21:21 +02:00
each time they are called:
1) the node ID,
2) the global time,
3) the local time (allowing for future introduction of per-node clocks),
2016-03-12 17:37:01 -08:00
4) the routing protocol type
- (traffic control) A traffic control sublayer has been added with the aim of
2019-07-02 16:21:21 +02:00
introducing an equivalent of the Linux Traffic +Control infrastructure into
ns-3. This layer sits in between the NetDevices (L2) and the network
protocol (e.g. IP). It is in charge of processing packets and performing
2016-03-12 17:37:01 -08:00
actions on them: scheduling, dropping, marking, policing, etc. Initial
support for flow control has been added to the PointToPointNetDevice;
backward-compatible support for other device types is provided.
- (traffic control) A three band priority queue modelled after Linux
pfifo_fast queueing discipline has been added.
- (traffic control) Adaptive RED extensions have been added to the RED model
- (wifi) A number of changes related to improving support for 802.11n/ac
models have been introduced.
1) Two rate controls compatible with High Throughput (HT) Wi-Fi modes
2019-07-02 16:21:21 +02:00
(e.g. 802.11n/ac), Ideal and MinstrelHT, have been added
2016-03-12 17:37:01 -08:00
2) Support for multiple spatial streams (MIMO) using existing SISO
error models
3) The WiFi helper API for the WifiMac sublayer, and the configuration
of HT modes and parameters, has been simplified
2018-06-28 12:51:39 +03:00
4) Better support for backward compatibility with legacy modes
2016-03-12 17:37:01 -08:00
- (wifi) 802.11g was made backward compatible with 802.11b networks
2019-07-02 16:21:21 +02:00
- (internet) L4 protocols (e.g., TCP, UDP, ICMP, etc.) can be demultiplexed
by IP according to the incoming interface. In other words, it is now
2016-03-12 17:37:01 -08:00
possible to use specialized L4 protocols according to the interface.
2019-07-02 16:21:21 +02:00
- (internet) Ipv6Address::IsAllHostsMulticast() is now deprecated.
2016-03-12 17:37:01 -08:00
FF02::3 is not in the official reserved IPv6 multicast address list.
2019-07-02 16:21:21 +02:00
- (internet) Ipv6Address::IsAll[Nodes,Routers]Multicast() now checks the
address scope beyond the simple link-local. Nodes are checked for
Interface-Local, Link-Local and Realm-Local, Routers for the above plus
2016-03-12 17:37:01 -08:00
Site-Local.
2019-07-02 16:21:21 +02:00
- (internet) Ipv6 routing protocols must now *not* forward packets to upper
layers unless for extremey specific cases. The Ipv6L3protocol handles
2016-03-12 17:37:01 -08:00
almost all the packets directed to the host.
2019-07-02 16:21:21 +02:00
- (internet) Ipv6 can now reject packets directed to an address not configured
2016-03-12 17:37:01 -08:00
on the interface they are received from (Strong End System Model, RFC 1222).
2015-12-03 00:35:35 +01:00
- (internet) UDP and Ipv6 RAW sockets can now join Ipv6 multicast groups.
2019-07-02 16:21:21 +02:00
Incoming packets will be filtered according to if there's a socket listening
2016-03-12 17:37:01 -08:00
to that group. Source filtering is left to the application.
2019-07-02 16:21:21 +02:00
- (network) ns-3 is now capable of serializing cooked (SLL) headers. This is
2016-03-12 17:37:01 -08:00
used in DCE to allow the generation of pcap directly readable by wireshark.
2019-07-02 16:21:21 +02:00
- (internet) It is now possible to set custom values for RipNg Link Down
2016-03-12 17:37:01 -08:00
(standard is 16).
2016-02-14 16:54:05 +01:00
- (internet) permanent (static) NDISC entries can be created for IPv6
2016-03-12 17:37:01 -08:00
- (internet) IPv4 RIPv2 protocol model is now available.
2015-09-15 16:13:22 -07:00

Release 3.24.1
==============
Release 3.24.1 is a maintenance release that fixes three issues:
- support for Xcode 7 clang compiler version
- detection of Python bindings location
- compilation problem on 32-bit gcc-4.4 machine
The issues prevented selected systems from being able to successfully
build ns-3, and prevented the released version from being able to
detect the presence of pybindgen used for Python bindings.

2014-09-19 11:47:30 -07:00
New user-visible features
-------------------------
2019-07-02 16:21:21 +02:00
- (wifi) Support for MPDU aggregation has been added to the wifi model,
2015-02-02 21:06:56 -08:00
as well as a number of related example programs.
2015-02-03 16:27:01 -08:00
- (wifi) Added two combined power and rate control mechanisms to the
wifi module. The new mechanisms, PARF and APARF, are the first in the
2019-07-02 16:21:21 +02:00
wifi module to jointly control transmission power and data rate. Two use
case examples (PowerAdaptationDistance and PowerAdaptationInterference)
2015-02-03 16:27:01 -08:00
and a test case have also been added.
2015-02-02 21:06:56 -08:00
- (lte) In previous releases of the LTE module, the bearer release
2014-11-28 16:56:26 +01:00
functionality was only partially supported. As an enhancement, a
complete release bearer procedure is now implemented, which can be
invoked by calling the new helper method
LteHelper::DeActivateDedicatedEpsBearer(). The related output can be
seen through the stats collected at different layers like PDCP, RLC,
2015-02-02 21:06:56 -08:00
MAC, PHY. To support this implementation, an example and test suite is
2019-07-02 16:21:21 +02:00
added within the LTE module examples and tests folder.
- (wave) Additional support has been added for WiFi-based vehicular networks,
including the channel-access coordination features of IEEE 1609.4 and a
comprehensive VANET routing example that includes a Basic Safety
Message (BSM) packet generator application and associated statistics
counters. Together, these allow users to evaluate the performance effects
in a VANET of varying transmission and channel properties (e.g., packet
rate, message size, transmit power, propagation loss model, impact of
2015-02-03 16:27:01 -08:00
routing protocol traffic, etc.).
2019-07-02 16:21:21 +02:00
- (internet) It is now possible to print the Neighbor Cache (ARP and NDISC)
2015-02-02 21:06:56 -08:00
by using the RoutingProtocolHelper
2019-07-02 16:21:21 +02:00
- (stats) A new TimeProbe class has been added to hook the data collection
2015-02-02 21:06:56 -08:00
framework to traced values emitting Time objects
- (documentation) the callback function signatures for all TraceSources
is documented in Doxygen
2015-02-05 16:39:39 -08:00
- (utils) print-introspected-doxygen.cc has had several enhancements;
2015-02-03 13:48:07 -08:00
use -h to read the usage message for details.
2015-02-05 16:39:39 -08:00
- (core) TracedValue and TracedCallback function signatures are now documented,
2015-02-03 13:48:07 -08:00
which required changing the TypeId::AddTraceSource API.

New user-visible features
-------------------------
2014-07-03 16:43:58 +02:00
- The LTE module now supports the transport of the S1-U, X2-U and X2-C
interfaces over emulated links via the new helper class EmuEpcHelper.
2014-08-14 12:46:11 -07:00
- CommandLine can now provide a shorthand argument name for any
Attribute.
2019-07-02 16:21:21 +02:00
- Implemented support for Frequency Reuse algorithms in LTE module, as the
outcome of GSoC 2014 project.
2014-09-05 01:12:55 +02:00
The project also includes several sub-features, such as:
- implementation of Downlink Power Control
- implementation of Uplink Power Control
2019-07-02 16:21:21 +02:00
- new DL-CQI generation approach, which increases throughput if FR algorithms
2014-09-05 01:12:55 +02:00
are used
2019-07-02 16:21:21 +02:00
- seven options of Frequency Reuse algorithms: LteFrNoOpAlgorithm,
LteFrHardAlgorithm, LteFrStrictAlgorithm, LteFrSoftAlgorithm,
2014-09-05 01:12:55 +02:00
LteFfrSoftAlgorithm, LteFfrEnhancedAlgorithm, LteFfrDistributedAlgorithm
2019-07-02 16:21:21 +02:00
- updated RadioEnvironmentMapHelper. Now RadioEnvironmentMap can be generated
for Data or Control channel and for specified RbId, what is helpful when
2014-09-05 01:12:55 +02:00
using FR algorithms
2014-09-13 08:47:05 -07:00
- Added a CoDel queue model. CoDel queues measure and control the queue
2019-07-02 16:21:21 +02:00
traversal delay. The ns-3 implementation is a port of the Linux
2014-09-13 08:47:05 -07:00
implementation.
- Added support for TCP timestamp and window scale options, and added
ability to trace the TCP slow start threshold value.
- SimpleNetDevice and SimpleChannel (used for adding basic link effects
2019-07-02 16:21:21 +02:00
for testing of higher-layer protocols) have been extended to support
2014-09-13 08:47:05 -07:00
the option of broadcast or PointToPoint link semantics. The bandwidth
and link delay can be constrained, and it uses an output queue.
2019-07-02 16:21:21 +02:00
- SimpleNetDevice and SimpleChannel can be installed in a node through
2014-09-13 08:47:05 -07:00
a new helper: SimpleNetDeviceHelper.
2014-09-10 06:09:45 +02:00
- Implemented new PacketSocketServer and PacketSocketClient applications.
2019-07-02 16:21:21 +02:00
The primary use is in tests, to avoid using the ones from the
2014-09-13 08:47:05 -07:00
application module that also bring in a dependency on the internet module.

New user-visible features
-------------------------
2013-12-13 10:50:45 +01:00
- Extension to UE measurements and improved handover algorithm models in LTE
module, as the outcome of GSoC 2013 project. The project also includes several
sub-features, such as:
- implementation of System Information Block Type 1 (SIB1);
- a new option for automatic UE attachment using Idle mode cell selection
procedure;
- improved configurability of UE measurements; and
- two options of handover algorithms for enabling automatic handover trigger
in LTE simulation: A2-A4-RSRQ and strongest cell (A3-RSRP).
2013-12-20 09:28:31 -08:00
- A new FixedRoomPositionAllocator has been added to the buildings
module. It allows one to generate a random position uniformly
2019-07-02 16:21:21 +02:00
distributed in the volume of a chosen room inside a chosen building.
2013-12-13 11:21:57 +01:00
- A new attribute ns3::LteRlcAm::TxOpportunityForRetxAlwaysBigEnough
allows to overcome the lack for re-segmentation in the RLC AM
implementation by assuming that the size of a TxOpportunity is
always big enough for the RLC AM PDU to be retransmitted.
- After some profiling, the code of LteMiErrorModel has been optimized
for speed, resulting in a significantly lower execution time of the
LTE model when used with the error model enabled.
2019-07-02 16:21:21 +02:00
- A new WiFi extension for vehicular simulation support is available in
the src/wave directory. The current code represents an interim capability
to realize an IEEE 802.11p-compliant device, but without the WAVE
extensions (which are planned for a later patch). The WaveNetDevice
2013-12-15 22:28:30 -08:00
modelled herein enforces that a WAVE-compliant physical layer (at 5.9 GHz)
2019-07-02 16:21:21 +02:00
is selected, and does not require any association between devices (similar
to an adhoc WiFi MAC), but is otherwise similar (at this time) to a
WifiNetDevice. WAVE capabililties of switching between control and
2013-12-15 22:28:30 -08:00
service channels, or using multiple radios, are not yet modelled.
- A new IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) model
is available. Using ns-3's naming convention, the acronym is expanded
2019-07-02 16:21:21 +02:00
to SixLowPanNetDevice. The SixLowPanNetDevice is able to act as a
shim between IPv6 and a NetDevice, compressing IPv6 headers according
to RFCs 4944 and 6262. The SixLowPanNetDevice is meant to be used over
IEEE 802.15.4 NetDevices, but it can be used on other NetDevices as
2013-12-15 22:28:30 -08:00
well (see the manual for full details). This model precedes the
general availability of an 802.15.4 model, so must be run in conjunction
with a wired NetDevice model for now, or with experimental versions of
802.15.4 models.
- It is now possible to use Ipv6PacketInfoTag from UDP applications in the
same way as with Ipv4PacketInfoTag. See Doxygen for current limitations in
using Ipv[4,6]PacketInfoTag to set IP properties.
2019-07-02 16:21:21 +02:00
2013-12-15 22:28:30 -08:00
- Ipv[4,6]Interfaces not respecting the minimum MTU requirements (68 octects
for IPv4 and 1280 octects for IPv6) will be automatically set as Down.
2019-07-02 16:21:21 +02:00
2013-12-15 22:28:30 -08:00
- IPv6 addresses and routing tables are printed in a more conventional way,
closely matching the Linux "route -A inet6" command.
2013-12-15 22:58:10 -08:00
- Additional time units (Year, Day, Hour, Minute) were added to the time
2019-07-02 16:21:21 +02:00
value class that represents simulation time; the largest unit prior to
2013-12-15 22:58:10 -08:00
this addition was Second.
2019-07-02 16:21:21 +02:00
- A new parallel scheduling algorithm based on null messages, a common
parallel DES scheduling algorithm, has been added. The null message
2013-12-15 22:58:10 -08:00
scheduler has better scaling properties when running on some scenarios
2019-07-02 16:21:21 +02:00
with large numbers of nodes since it does not require a global
2013-12-15 22:58:10 -08:00
communication.

New user-visible features
-------------------------
2013-07-11 14:45:51 -07:00
- Time attributes can now be bounded. See attribute-test-suite.cc for an
example.
2013-08-09 04:35:13 -07:00
- Data collection components have been added to the stats module. These
components can be used to generate time series data in files and plots.
- IPv6 address class 2001:db8::/32 is now dropped by routers (RFC 3849).
2013-07-11 14:45:51 -07:00
- New generic hash function interface. Two hash functions are provided:
murmur3 (default), and the venerable FNV1a. See the Hash Functions
section in the Manual.
2019-07-02 16:21:21 +02:00
- New Mac16Address has been added, Mac64Address is now in-line with
Mac48Address and all the three can be used in IPv6 autoconfigure.
2013-07-29 14:07:42 +02:00
- Previously, the use of Building models was limited to the use of the
companion BuildingsMobilityModel. Now, any MobilityModel can be

New user-visible features
-------------------------
2012-07-10 22:24:37 -07:00
- A new random variable base class called 'RandomVariableStream', has been
2019-07-02 16:21:21 +02:00
introduced. This base class derives from ns3::Object, unlike the current
'RandomVariable' class which is a special type of object in the ns-3
system to date. By making this class derive from ns3::Object, it can be
2012-08-26 13:35:52 -07:00
handled with the Ptr class, can carry attributes, and can have its parameters
and initial state saved in the config-store subsystem. A new attribute
called "Stream" has been introduced for this class, to allow users to
better control the assignment of underlying pseudo-random sequences to
the RandomVariableStream objects (bug 101).

New user-visible features
-------------------------
2012-05-26 23:12:17 -07:00
- Transport protocol implementations (TCP, UDP) have been refactored to
2019-07-02 16:21:21 +02:00
support also IPv6 connections. Dual-stacked IPv6 sockets are implemented.
An IPv6 socket can accept an IPv4 connection, returning the sender's
address as an IPv4-mapped address (IPV6_V6ONLY socket option is not
2012-05-26 23:12:17 -07:00
implemented).
2012-06-05 11:24:59 -07:00
- The LTE code from the LENA project has been merged, bringing in a
2012-05-26 23:12:17 -07:00
significant redesign of the LTE module as well as many new features.
2012-04-11 12:23:10 +02:00
- An antenna module is now included, which includes different
radiation pattern models. See the corresponding new section of the
2012-05-08 16:09:49 +02:00
ns-3 models library documentation for details.
2012-05-11 16:42:40 +02:00
- A new buildings module is introduced which allows to model the
2019-07-02 16:21:21 +02:00
presence of buildings in a wireless network topology.
2012-05-11 16:42:40 +02:00
- New propagation models (OkumuraHata, ITU-R P.1411, ITU-R P.1238)
have been added
2012-05-26 23:12:17 -07:00
- The Dynamic Source Routing (DSR) MANET routing protocol for IPv4 was added.
- A Random Early Detection (RED) queue model has been added.
2019-07-02 16:21:21 +02:00
- Ipv6RoutingHelper is now in-line with Ipv4RoutingHelper concerning the RT
print functions. Various minor changes were made in Ipv6RoutingProtocol and
2012-05-26 23:12:17 -07:00
derived classes to make this possible.
2019-07-02 16:21:21 +02:00
- New "SendIcmpv6Redirect" attribute (and getter/setter functions) to
2012-05-26 23:12:17 -07:00
Ipv6L3Protocol. The behavior is similar to Linux's conf "send_redirects",
i.e., enable/disable the ICMPv6 Redirect sending.
- Longer and more descriptive names are used for error units in RateErrorModel
class and queue mode in Queue class. Attributes in those classes are also
changed for consistency. See API documentation for details.
2012-06-05 11:24:59 -07:00
- The netanim animator is now bundled with the release.

New user-visible features
-------------------------
2011-07-05 19:03:55 +02:00
- SpectrumChannel models now support the usage of single-frequency
propagation loss models based on the PropagationLossModel
class. These model can be used in conjunction with
the frequency-dependent propagation loss model based on the
SpectrumPropagationLossModel class already supported by
2019-07-02 16:21:21 +02:00
SpectrumChannel.
2011-07-05 19:03:55 +02:00

New user-visible features
-------------------------
2011-05-22 23:14:56 -07:00
- The build system has been modularized, and the source code reorganized,
to allow for modular libraries instead of a single monolithic ns-3
library. User programs now link a number of smaller, per-module
2019-07-02 16:21:21 +02:00
libraries depending on the dependencies expressed to the build system.
2011-05-22 23:14:56 -07:00
Source code is now being maintained in individual modules with
consistent directory structures.
- Python bindings have also been modularized, and the bindings are now
generated into a 'ns' namespace instead of 'ns3' for the old
(monolithic) bindings. By default the bindings are now modular, with
2019-07-02 16:21:21 +02:00
a backward compatibility layer for older programs.
2011-05-22 23:14:56 -07:00
- By default, example and test programs are disabled from the build.
Users can enable them via the use of a waf command at configure time,
or automatically through the use of a new .ns3rc file.
2011-04-17 14:23:18 +02:00
- int64x64_t is a new type which allows portable and easy to write arithmetic
calculations that require a high degree of fractional precision.
2011-05-22 23:14:56 -07:00
- An interface to the Click Modular Router and an Ipv4ClickRouting
class has been added, to allow a node to use Click for external routing.
- An interface to an OpenFlow software implementation distribution has
been added to allow the simulation of OpenFlow switches in ns-3.
- ns-3 coding style requirements have been applied to the entire coding
2019-07-02 16:21:21 +02:00
base, resulting in a large number of whitespace changes. The coding
style has been automatically enforced by running a style checking
2011-05-22 23:14:56 -07:00
program (utils/check-style.py) that uses the uncrustify (v. 0.58)
2019-07-02 16:21:21 +02:00
program to apply changes.
2011-05-15 09:28:09 -04:00
2011-05-22 23:14:56 -07:00
- Some documentation reorganization to split documentation between
2019-07-02 16:21:21 +02:00
the ns-3 manual (primarily focusing on the ns-3 core) and a new
2011-05-22 23:14:56 -07:00
"model library" document has been started.

Supported platforms

2010-12-29 11:05:41 -08:00
ns-3.10 has been tested on the following platforms. Not all features are
available on all platforms; check the Installation page on the project wiki.

New user-visible features
-------------------------
2019-07-02 16:21:21 +02:00
- NS-3 PyViz, a live simulation visualizer, has been added. The
2010-12-08 14:19:44 -08:00
visualizer interacts with a running simulation, such that it uses no
trace files. It can be most useful for debugging purposes, i.e. to
figure out if mobility models are what you expect, where packets are
being dropped, etc. There is also a builtin interactive python console
that can be used to debug the state of the running objects. Although
it is mostly written in Python, it works both with Python and pure C++
simulations.
2010-12-02 07:51:34 +00:00
- Wi-Fi MAC high classes have been reorganised in attempt to
consolidate shared functionality into a single class. This new
class is RegularWifiMac, and it derives from the abstract
WifiMac, and is parent of AdhocWifiMac, StaWifiMac, ApWifiMac,
and MeshWifiInterfaceMac. The QoS and non-QoS class variants are
no longer, with a RegularWifiMac attribute "QosSupported"
allowing selection between these two modes of
operation.
2010-09-02 14:30:44 +01:00
- Support for IEEE 802.11g (specifically, rates with Modulation
Class ERP-OFDM) has been added to the wifi module. The new
WifiModes have names of the form ErpOfdmRatexxMbps, where xx is
the rate in Mbps (one of 6, 9, 12, 18, 24, 36, 48, 54), and a
WifiPhyStandard enumeration WIFI_PHY_STANDARD_80211g has been
added to allow configuration of a Wi-Fi STA supporting ERP-OFDM,
HR/DSSS, and DSSS rates (which some call an "802.11b/g" station).
2010-10-05 01:33:25 -07:00
- Two attributes were added to WaypointMobilityModel. The first
"LazyNotify" (default false), if enabled to true, will suppress
course change notifications if there are no position updates.
The second, "InitialPositionIsWaypoint" (default false), if enabled,
will allow an initial call to SetPosition () (before any waypoints
have been added) to be treated as the first waypoint.
2010-11-08 11:36:26 -08:00
- Regression testing is now completely performed within test.py
rather than a separate "./waf --regression" that consults
reference traces in the ns-3.x-ref-traces directory. In most
2019-07-02 16:21:21 +02:00
cases, the example programs whose traces were included in
2010-11-08 11:36:26 -08:00
ns-3.x-ref-traces have a corresponding test called from the
test.py program. It is still possible to write trace-based
regression tests but they are now called from the test.py
program.
2019-07-02 16:21:21 +02:00
- New BulkSendApplication sends data as fast as possible up to
MaxBytes or unlimited if MaxBytes is zero. Think OnOff, but
without the "off" and without the variable data rate. This
application only works with SOCK_STREAM and SOCK_SEQPACKET
2010-12-16 20:24:14 -05:00
sockets, for example TCP sockets and not UDP sockets.
2019-07-02 16:21:21 +02:00
- Extensions to the energy models: 1) a new Rakhmatov Vrudhula
non-linear battery model, 2) additional support for modeling
energy consumption in WiFi devices, 3) an example for how to add
energy models to a WiFi-based simulation (in examples/energy/
2010-12-20 15:49:12 -08:00
directory).
2010-12-20 22:05:44 -08:00
- New methods to print IPv4 routing tables to an output stream.
2010-12-23 12:40:48 -08:00
- A replacement implementation for TCP for IPv4. TcpSocketBase
now replaces TcpSocketImpl. There are subclasses defined for
TCP Tahoe, Reno, NewReno, and the original RFC793 without
congestion control.
2010-12-21 21:44:11 -08:00
- Energy support for UAN module and Li-Ion energy model.
Now each network node can have an associated energy source
from which it consumes energy. The user can specify a custom
energy model for the underwater transducer, with default values
set for WHOI acoustic transducer. Li-Ion battery model added
into energy models folder.
2019-07-02 16:21:21 +02:00
- Destination-Sequenced Distance Vector (DSDV) routing protocol
is a proactive, table-driven routing protocol for MANETs
developed by Charles E. Perkins and Pravin Bhagwat in 1994.
This implementation is for IPv4 routing and was contributed
2010-12-21 22:43:06 -08:00
by ResilNets Research Group.
2019-07-02 16:21:21 +02:00
- A novel model to simulate LTE networks has been added. It focuses
mainly on modeling the E-UTRA part of the system, with a particular
attention on the aspects related to the channel, PHY and MAC layers.
The most important features available at this moment are (i) a basic
implementation of both the UE and the eNB devices, (ii) RRC and
entities for both the UE and the eNB, (iii) an Adaptive Modulation
and Coding (AMC) scheme for the downlink, (iv) the management of the
data radio bearers (with their QoS parameters), the MAC queues and
the RLC instances, (v) Channel Quality Indicator (CQI) management,
(vi) support for both uplink and downlik packet scheduling,
(vii) a PHY layer model with Resource Block level granularity, and
(viii) a channel model with the outdoor E-UTRAN propagation loss
2010-12-29 11:05:41 -08:00
model.
2019-07-02 16:21:21 +02:00
- Project documentation has been converted from GNU Texinfo to Sphinx.

New user-visible features
-------------------------
2010-06-16 10:55:13 +01:00
- A reorganisation of the construction of Wi-Fi transmit rates has
been undertaken with the aim of simplifying the task of
supporting further IEEE 802.11 PHYs. This work has been completed
under the auspices of Bug 871. A consequence of this work is that
WifiModes have a new (hopefully future-proof) naming, and
simulations which specify rates by name will need updating. The
list of new rate names is given in the error message produced
when an attempt is made to use any invalid rate name (including
those that were previously valid).
2010-06-15 10:28:51 -07:00
- A new OFDM error rate model for WiFi (NistErrorRateModel); this model
has been validated in clear-channel testbed tests. For 802.11b, it
uses the same underlying model as the YansErrorRateModel, but it differs
2010-07-20 07:34:14 -07:00
from YansErrorRateModel for OFDM modes (802.11a/g). The default
YansWifiPhyHelper has been changed to use this model.
2010-05-15 16:46:47 -07:00
2019-07-02 16:21:21 +02:00
- A new NS-2 mobility trace reader supports BonnMotion, SUMO, TraNS,
2010-06-20 17:25:42 +04:00
etc. traces.
2010-07-07 21:54:32 -07:00
- An energy model for nodes and devices, including an energy source
model and device energy models allowing energy-aware devices
2019-07-02 16:21:21 +02:00
to notify the energy source about energy consumption.
2010-07-07 21:54:32 -07:00

2019-07-02 16:21:21 +02:00
- Underwater Acoustic Network (UAN) model, split in to three parts, the
channel, PHY, and MAC models to enable researchers to model a variety
2010-08-09 14:05:48 -04:00
of underwater network scenarios.
2010-11-09 12:56:50 +01:00
- the Spectrum framework, which provides support for spectrum-aware
Channel and PHY layer modeling. It features a set of classes that
allows the mathematical representation of frequency dependent
phenomena. Some example channel, propagation and device
implementations that make use of this framework are also
2019-07-02 16:21:21 +02:00
included.

New user-visible features
-------------------------
2019-07-02 16:21:21 +02:00
a) WiMAX net device: Allow to simulated IEEE 802.16 point to multi-point based networks
2010-01-31 16:19:23 -05:00
2019-07-02 16:21:21 +02:00
b) Distributed simulation for point-to-point networks using the Message
2010-03-08 21:07:31 -05:00
Passing Interface (MPI) standard.
2019-07-02 16:21:21 +02:00
c) Matrix propagation loss model uses a two-dimensional matrix of path loss indexed
2010-03-09 11:54:40 +03:00
by source and destination nodes.
2019-07-02 16:21:21 +02:00
d) Topology read system: Allows quick and easy creation of large topologies by reading
2010-03-29 12:21:07 -04:00
Inet or Orbis files
2019-07-02 16:21:21 +02:00
e) Gauss-Markov mobility model: Adds 3-d adaptation of Gauss-Markov mobility model which
2010-03-29 12:21:07 -04:00
has both memory and variability
2019-07-02 16:21:21 +02:00
f) Steady-state random waypoint mobility model: Based on random waypoint mobility (RWM) model for case when
speed, pause and position are uniformly distributed random variables. However, initial values of these
2010-03-29 12:21:07 -04:00
parameters are not from uniform distribution but from stationary distribution of RWM model.
2019-07-02 16:21:21 +02:00
g) Two-ray ground propagation loss model: Calculates the crossover distance under which Friis is used.
The antenna height is set to the nodes z coordinate, but can be added to using the model parameter
2010-03-29 12:21:07 -04:00
SetHeightAboveZ, which will affect ALL stations

2019-07-02 16:21:21 +02:00
Warning: among API changes in this release, Application::Start and
2008-06-03 07:09:40 -07:00
Application::Stop now interprets the time argument as a relative
instead of absolute simulation time, to align with how Simulator::Schedule
2019-07-02 16:21:21 +02:00
behaves. Any code that calls these APIs in the middle of the simulation
will need to be adapted.
2008-06-03 07:09:40 -07:00
2019-07-02 16:21:21 +02:00
The API of Simulator::StopAt (time) has also changed. Now it is
called Simulator::Stop (time), and takes a relative time, instead of
2008-06-03 07:09:40 -07:00
absolute.
