| 摘 要： | 实现服务质量(Qualityof Service,QoS)路由是移动无线自组网(Mobile Adhoc Networks,MANET)中的核心问题,同时也面临着巨大的挑战。文章提出了一种支持QoS路由的三层路由算法,算法框架由SSCA、DSRU和SQAR三个子算法构成。SSCA负责网络拓扑结构的管理、DSRU负责路由信息的更新、SQAR负责进行QoS选路。笔者在GloMoSim模拟器上实现了该算法,结果表明该算法和现有算法相比,显著地提高了网络的吞吐量和延时特性。

| Abstract: | To support Qos routing in MANET(Mobile Ad hoc Networks) is core issue in research of MANET.In this article,it proposes a three-tier framework supporting the Qos routing.The framework contains three cooperative algorithms,SSCA,DSRU and SQAR.SSCA is mainly responsible for topology management,DSRU is responsible for updating the routing information and the responsibility of SQAR is to select path which satisfies the QoS requirement.It simulates this framework on the Glomosim environment and the result shows that the framework's strongpoint on throughput and stability of entire network. |
