Enabling multiple controllable radios in OMNeT++ nodes

This work describes our implementation of a framework that allows mobile nodes in OMNeT++ simulations to be equipped with multiple radio subsystems that can be dynamically suspended and woken up. Our framework enables the simulation of wireless architectures that exploit radio hierarchies for power-efficient neighbor and service discovery and connection setup. The design is implemented as an extension of the MiXiM framework and is maintained as a MiXiM branch.
