Performance Evaluation of CSMA/TDMA Cognitive Radio Using Genetic Algorithm
Channel Assignment is a very important issue in the field of Wireless Networks. In this paper, the authors have evaluated the performance of a Multiple Channel TDMA/CSMA spectrum sharing scenario. They have combined the TDMA and the non-persistent CSMA system with multiple channels and analyzed the throughput and the throughput performance of the individual systems as a function of the actual offered traffic level. In this paper, they have analyzed TDMA and CSMA in Cognitive Radio, where the primary users have higher priority than secondary users and secondary users need to monitor the channel in order to avoid the interference to the primary users.
