-   * Software delay models random small internal delay to avoid simultaneous operation of 
-   * different mesh points (e.g. on power on). 
-   * 
-   * Software delay is calculated as uniformely distributed random value between zero and

-   * for example, beacon is formed at software delay before putting it to the queue.
