Joint beamforming based achievable rate improvement on genetic algorithm using multiple relay paths for power and channel allocation on cognitive radio network.. In

The channel assignment protocol that allows opportunistic sharing of channels. At first the MAC layer algorithm chosen for WRANs that is suitable when neighboring

We propose a protocol called WiSP (channel Width Selection based on Packet size) to estimate the appropriate channel widths depending on the relative traffic load involving short

In the former scenario, cognitive radio has to sense the spectrum for the availability of channel, prepares and updates the candidate list comprising of
