摘　　要：针对有线网络已经不能满足人们对信息的获取要求的问题,设计一种基于集中式动态分配的TDMA无线网格网MAC协议。基于分多址技术(time division multiple access,TDMA),分别分析了分布式和集中式TDMA网络结构。建立了一种集中式TDMA网络模型,得到模型的时隙分配过程,并对该网络设计协议进行opnet仿真测试。仿真结果表明:集中式动态TDMA协议时延较小,丢包大小也较少,性能较为均衡。We designed a time division multiple access （TDMA） wireless mesh network MAC protocol based on centralized dynamic allocation aiming at the problem that wired network cannot meet the requirement of getting information. We analyzed the distributed and centralized TDMA network structures separately based on TDMA. Then we built a centralized TDMA network model, got the time slot assignment progress of the models, and did opnet simulation tests to the network design protocol. The simulation results show that the centralized model has less time-delay and package-loss, has a more balanced performance.
