摘　　要：在认知Mesh网络中,认知节点可在多个信道中进行切换,从而对网络的路由选择和链路建立产生影响。文中将认知Mesh网络中的路由协议和MAC协议进行联合设计,有效避免了交叉节点频繁切换信道带来的"耳聋问题"和无线传输中的隐藏终端问题。仿真表明该联合策略能在占用相同信道资源的情况下,有效利用不同区域中空闲的授权信道来提高系统的整体吞吐量。Nodes in cognitive mesh networks can change their communication channel actively,which affects routing and link establishing.A joint routing and MAC access scheme for cognitive mesh networks were proposed that avoid 'Deafness Problem' induced by changing channel frequently and hiding terminal in wireless communication.Simulation results show that,in the scenario of networks that have the same special channel resource,this scheme can provide better throughput by utilizing unoccupied primary channels effectively.
