I'm pleased to announce the ns-3.19 release, available at the following URL:


This release features LTE model extensions to UE measurements and 
improved handover algorithm models, and a new WiFi extension for 
vehicular simulation support to realize an IEEE 802.11p-compliant 
device.  A new IPv6 over Low power Wireless Personal Area Networks 
(6LoWPAN) model is available, intended in the future to enable IPv6 over 
sensor network models.  A new FixedRoomPositionAllocator has been added 
to the buildings module. It allows one to generate a random position 
uniformly distributed in the volume of a chosen room inside a chosen 
building.  Also regarding LTE, the code of LteMiErrorModel has been 
optimized, resulting in a significantly lower execution time of the LTE 
model when used with the error model enabled.  A new parallel scheduling 
algorithm based on null messages, a common parallel DES scheduling 
algorithm, has been added.  The null message scheduler has better 
scaling properties when running on some scenarios with large numbers of 
nodes since it does not require a global communication.  Finally, some 
patches were added to facilitate easier use of ns-3 with the mininet 

As usual, thanks to the several contributors of new model code and to 
everyone who has worked to fix bugs and to improve the documentation 
during this release cycle.  We'll start some discussion after the 
holiday break about the next release cycle and overall roadmap.
