摘要: 无线Ad hoc网络的应用环境要求它必须提供一定的服务质量保证(QoS),然而,无线信道固有的特点及节点移动造成网络拓扑的频繁变化,使得在无线Ad hoc网络中支持QoS面临许多新的挑战。对Ad hoc网络原有的路由协议AODV进行了改进,使其能够满足一定的QoS要求。然后通过NS-2对其进行了仿真,并比较了改进后的AODV协议和原AODV、DSDV协议的性能。

关键词: AODV, QoS, Ad hoc网络, 路由协议

Abstract: The application environments require that wireless Ad hoc networks should support Quality-of-Service(QoS).But in a wireless Ad hoc network,supporting QoS is very difficult due to the inherent characteristics of wireless channel and the frequent change of network topology.This paper presents an improved AODV route protocol in order to support better QoS performance,then it is simulated by Network Simulator 2(NS-2),and compare its performance with traditional AODV,DSDV protocol.

Key words: AODV, Quality-of-Service(QoS), Ad hoc networks, routing protocol
