Simulation of Cognitive Radio Networks in OMNeT++
A widespread methodology for performance analysis and evaluation in communication systems engineering is network simulation. It is widely used for the development of new architectures and protocols. Network simulators allow to model a system by specifying both the behavior of the network nodes and the communication channels, and Cognitive Radio (CR)-related research activities have been often validated and evaluated through simulation too.
Following this approach, this chapter presents an ongoing effort towards the development of a CR simulation framework, to be used in the design and the evaluation of protocols and algorithms. OMNeT++, in combination with MiXiM framework functionalities, was chosen as the developing platform, thanks to its open source nature, the existing documentation on its architecture and features, and the user-friendly Integrated Development Environment (IDE).
Part of this work was supported by COST Action IC0902 “Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks” and by the ICT ACROPOLIS Network of Excellence, FP7 project n. 257626.
