ns-3.8 Released

ns-3.8 has been released and is immediately available for download here.

A plethora of new features have been included with this release. They are listed below:
  1. WiMAX Net Device:
    Allow to simulate IEEE 802.16 point to multi-point based networks.

  2. MPI Based Parallelization:
    Distributed simulation for point-to-point networks using the MPI standard.

  3. Matrix Propagation Loss Model:
    This model uses a two-dimensional matrix of path loss, indexed by source and destination nodes.

  4. Topology Read System:
    Allows quick and easy creation of large topologies by reading Inet or Orbis files.

  5. Gauss-Markov Mobility Model:
    Adds 3-D adaptation of Gauss-Markov mobility model which has both memory and variability.

  6. Steady-state Random Waypoint Mobility Model:
    Based on random waypoint mobility (RWM) model for cases when speed, pause and position are uniformly distributed random variables. However, initial values of these parameters are not from uniform distribution, but from a stationary distribution of RWM model.

  7. Two-ray Ground Propagation Loss Model:
    Calculates the crossover distance under which Friis is used. The antenna height is set to the node's z-coordinate, but can be added to using the model parameter SetHeightAboveZ, which will affect *all* stations.
A long list of bug fixes have also been included with this release. A complete list is available here.

The tentative date of release for the next version, ns-3.9, is August 5th.
