Abstract

Throughput, delay and collision probability are all the important performance for cognitive radio networks. This paper proposes a state transition model and analyzes the performances of the cognitive radio networks with spectrum sensing and access operate simultaneously and conventional cognitive radio networks. The closed form expressions of the throughput, delay and collision probability in two sensing modes are derived. It is showed that the cognitive radio networks with spectrum sensing and access operate simultaneously has obvious advantage over the conventional one in the throughput, delay and collision probability. Simulation results verify the theoretical analysis.
