Simulated Evolution is the umbrella name for a set of projects focused on using agent-based modeling to explore and learn about evolutionary processes.
At present, modeling & simulation is the only paradigm which allows the simulation of complex behavior in a given environment's cognitive radio networks. Network simulators like OPNET, NetSim, MATLAB and NS2 can be used to simulate a cognitive radio network. Areas of research using network simulators include:
