| 摘 要： | 自组网是由一组带有无线收发装置移动节点组成的一个能够支持多跳的临时性计算机通信网络，其拓扑的动态变化是该类网络的一个重要特征，文章提出了一种满足QoS约束的自适应路由算法，将业务的多个QoS参数进行综合评判，对比各条路径综合路由状态，选择出最适合业务请求的路径。仿真显示该算法在支持QoS的同时，对移动Ad Hoc网络因拓扑动态变化而引起的信息不精确性有很好的适应度。

| Abstract: | Ad Hoc network is a temporary multi-hop wireless computer communication network that is composed of mobile hosts communicating with each other through wireless links.Dynamic topology is a typical character.A new QoS routing algorithm for mobile Ad Hoc networks,which is named QoS-Aware Self-Adaptive Routing Algorithm(QA-SARA),is proposed in this paper.It integrates the multiple QoS parameters of traffic into one request that is represented by integrated judgment.QA-SARA compares the integrated QoS value of each path and selects the most appropriate one according to the operation rules.Simulation results show that QA-SARA can tolerate the imprecise information which is caused by the dynamic network topology well while supporting QoS function. |
