Abstract :
In this paper, we investigate p-persistent random access used for a spectrum sensing cognitive radio network with multiple secondary users to avoid a collision. Effect of the imperfect sensing, false alarm and miss detection, is considered. We analyze the total throughput of the secondary network and propose throughput optimization algorithm. It is shown that simulation results well match with analysis results.
