Multiple access protocol with QoS support for mobile Ad Hoc networks

  • 摘要: 基于随机竞争和冲突解决的思想,为多跳移动Ad Hoc网络提出了一种支持服务质量(QoS)的多址接入(QMA)协议.将业务负载划分为时延敏感的实时业务和非时延敏感的数据业务.按照该协议,节点在发送业务分组前利用预报突发进行竞争接入,节点按照业务分组时延情况确定预报突发的长度,所发预报突发能持续到最后的节点优先获得接入.同时,具有实时业务的节点可以按照其优先级在更早的竞争微时隙中开始发送预报突发,因而可以比发送数据业务的节点更优先接入信道.最后利用OPNET仿真评估了QMA协议的多址性能,通过与带冲突避免的载波侦听(CSMA/CA)协议比较表明,QMA协议可以提供较高的吞吐量和较低的消息丢失率,并能为实时业务提供较低的时延,从而实现了对多媒体业务的QoS支持.
