Proactive spectrum handoff protocol for cognitiv e radioad hocnetwork and analytical evaluation

Spectrum handoff in cognitive radio technology has been emerged as a new method for improving performance of the cognitive radio networks. The authors propose a proactive spectrum handoff protocol based on a single rendezvous (SRV) coordination scheme without common control channel. This protocol utilises a multi-user greedy channel selection method to select the best channel based on minimum service time for the secondary users to achieve a higher aggregate thro ugh put. The authors pro pose d a novel t eoretical analysis to evaluate the aggregate th roughput of the secondary users in the proposed protocol
