Abstract
Frequency spectrum is a limited resource for wireless communications. Cognitive radio provides an approach to efficient utilization of spectrum. Spectrum handoff is an indispensable component in cognitive radio networks to provide resilient service for the secondary users. In this paper, we analyze the handoff performance of an opportunistic spectrum sharing systems over a coverage area. In the OSS systems, If an active secondary user detects the arrival of a primary user on a given channel, it releases the channel and switches to another idle channel. If no channel is available, the call waits in a buffer until either one channel becomes available or a maximum waiting time is reached. We examine the performances in terms of the link maintenance probability and mean handoff numbers of the secondary user’s. In the last, we prove the simulation result in session V.
