摘　　要：在多接口多信道无线Mesh网络(Multi-Radio Multi-Channel Wireless Mesh Network,MRMC-WMN)中使用定向天线能够有效减少干扰,但是增加了传输次数,有时会使网络性能恶化.为了获得良好的网络性能,文章综合运用定向天线技术、无线广播优势(Wirelesss Broadcast Advantage,WBA)和定向节点同信道干扰(Directional Node Co-Channel Interference,DNCI)判据来改善MRMC-WMN性能,提出了干扰感知波束信道选择多播路由(Interference-Aware Beam-Channel Selection Multicast Routing,IBSMR)算法,解决了MRMC-WMN中多播树的构建以及波束信道的选择问题,有效控制了传输次数,减少了干扰.仿真结果表明,与WCTB和MIMCR这两种多播路由算法相比,该算法能够更加有效地改善MRMC-WMN网络的整体性能.Using directional antenna in Multi-Radio Multi-Channel Wireless Mesh Network(MRMC-WMN)can effectively reduce the interference,but it increases the number of transmission and sometimes worsens the network performance.In order to improve the performance of MRMC-WMN,directional antenna technology,wireless broadcast advantage(WBA)and directional node co-channel interference(DNCI)metric are combined to improve the performance of MRMC-WMN,and Interference-Aware Beam-Channel Selection Multicast Routing(IBSMR)algorithm is proposed.It solves the problem of multicast tree construction and beam channel selection in MRMC-WMN,effectively controls the number of transmission and reduces the interference.Simulation results show that compared with WCTB and MIMCR,this algorithm can improve the overall performance of MRMC-WMN network more effectively.
