摘    要:基于预约轮询接入的思想,提出了TPMA(Time—dependentPerfectschedulingMultipleAccess)协议,其控制原则是有信息分组的节点进入轮询队列,群内中心节点选择出有最长等待时间分组的节点,并按照门限服务规则进行无冲突发送。实验仿真证明,该方案减小了信息分组的平均等待时间,明显改善了系统性能。

关 键 词:分布式无线网络  轮询系统  TPMA协议  排队模型  等待时间

Abstract:Waiting-time dependent Multiple Access Protocol is described on the idea of polling access,in this protocol,only the nodes that have packets to send enter the polling queue,head nodes in the Distributed Wireless Networks select the node which has the longest waiting time packet and serve its packets with Gate Regulation.Simulation proves that this protocol reduces waiting time of packet and improves performance of system obviously.
Keywords:distributed wireless ad hoc network  polling system  Time dependent Perfect Multiple Access Protocol  queuing model  waiting time
