Cooperative Algorithm forCognitive Radio Networks Which isBased onAdaptive Election

Recently manyresearchers devote themselves to scheming newprotocols forsensing, miningandmanaging spectrum efficiently. Inthis paper, weidentify thetrends that mobility ofcognitive users should beconsidered innearfuture andfixed cooperation modelshavelimited valueinmultiple cognitive usernetworks. Associated withsmartantenna communication systemapproach, we propose anintelligent cooperation modelwhichisbasedonadaptive election rules. Besides, we present howtosearchuseful relaynoteswhen cognitive userarefinding goodpartners todetect primary user. Furthermore, weillustrate this newmethodandshowyouhow toaccelerate theprocess ofsearching optimal relay userand promotedetection agility. Finally, wesimulate ouralgorithm by usingnetworksimulation platform andconclude with several openresearch issues ofthis newalgorithm.
