steam-sim
An accurate, scalable, and energy-aware simulator for WSNs
...Network behavior in terms of wireless channel models are provided by the PAWiS
and the MiXiM framework.
STEAM-Sim is an extension to the PAWiS and MiXiM framework. The underlying
simulator is OMNeT++. Please see the corresponding documentation.
I also ported the Contiki v2.6 operating system to STEAM-Sim, thus it is possible
to run Contiki-based code in the simulation.
