Abstract:
Cognitive radio is a promising technology for the next generation of wireless networks. Performance analysis of multiple access protocols in cognitive radio networks has been presented in the literature, but only considering the unreal situation of perfect channel sensing. In this paper, we extend an analytical model previously proposed to evaluate the performance of a cognitive radio network using Slotted Aloha and CSMA (Carrier Sense Multiple Access) multiple access protocols. In our new model, we consider imperfect channel sensing, resulting in more realistic performance analysis. After that, we investigate the influence of the parameters related to the performance of the channel sensing process in the performance of the network.
