Abstract :
With the flourishing development of wideband wireless communication, wireless spectrum resource gets scarcer. Base on spectrum sensing of cognitive radio, we apply it in multi-channel MAC protocol of wireless mesh network, and propose a new multi-channel MAC protocol for cognitive wireless mesh network (CWMN-MMAC) in this paper. Depending on distributed spectrum sensing and negotiation of cognitive users, it can allocate unused spectrum to unlicensed users dynamically and improve utilization of spectrum resource effectively. Through simulation, we analyze the influence of ATIM window to the throughput and channel utilization when licensed user is absent.
