MANETs网络中的一种分布式同步预约多址接入协议

提出了一种MANETs网络中的多址接入控制协议——分布式同步预约多址接入协议（DSRP），解决了隐藏终端和暴露终端问题，并且为实时业务的QoS要求提供了保障．协议以时分多址为基础，给不同类型的业务分配不同的优先级，采用不同的机制对空闲时隙进行竞争及预约．在已预约的时隙中采用发送数据前的预约确认机制，避免了入侵终端问题．在全连通网络中分析了DSRP协议的吞吐量和分组平均丢弃率，并且对协议进行了仿真，结果表明该协议能够达到传输实时业务的要求，适用于MANETs网络．

A distributed synchronous reservation multiple access control protocol for mobile Ad Hoc networks

This paper proposes a new multiple access control(MAC) protocol named distributed synchronous reservation multiple access control protocol(DSRP),in which the hidden and exposed terminal problems are solved,and the QoS(Quality of Service) requirements for real-time traffic are ensured.The protocol is based on Time Division Multiplex Address(TMDA) and a different type of traffic is assigned to different priority,according to which a node should compete for and reserve the free slots in a different method.Moreover,there is a reservation acknowledgement process before the data transmitting in each reserved slot,so that the intruded terminal problem is solved.The throughput and packets average drop probability of this protocol are analyzed and simulated in a fully connected network,the results of which indicate that this protocol is efficient to supporting real-time traffic and more suitable to MANETs.
