Abstract

In this paper, we discuss a p-persistent CSMA protocol based on-off source model in a cognitive radio network. Then the system model for primary user and cognitive user is analyzed in cognitive radio network, which using discrete event-driven simulation scheme. The article demonstrates various results such as cognitive user packet dropping probability and channel utilization rate, according to different values of p. The result shows that according to the network loading dynamically adjust the values of p can reduce the network collision probability and avoid network congestion. This paper offers a reference to the choice of p.
