摘    要:在基于IEEE 802.16的无线Mesht网络中,时隙分配算法对网络性能有重要影响.针对现有时隙分配算法只研究上行链路且时隙分配的结果导致中继节点在转发数据时频繁在相邻时隙间进行收发切换的问题,提出了一种上下行链路通用的时隙分配方法,对于上行链路,跳数较小节点的数据优先传输,而对于下行链路,跳数较大节点的数据优先传输,在传输路径上采用逐跳传输的策略.仿真结果证明了该算法的有效性.

关 键 词:无线MESH网络  集中调度  时隙分配

Abstract:In the IEEE 802.16 based wireless mesh networks,the network performance is influenced deeply by the slot allocation algorithm.The existing algorithm focuses mainly on the uplinks and its allocation result leads to the relay node switchwing frequently between transmission and reception within adjacent time slot when forwarding traffic.To resolve those problems,a uniform slot allocation algorithm is proposed for both uplinks and downlinks.For uplinks,the traffic of the node with smallest hop count is transfer...
