一种基于移动Ad hoc网络的QoS路由协议

A QoS Routing Protocol Based on Mobile Ad hoc Networks

移动A d hoc网络以其不依赖于任何预设的网络设施而能够临时快速自动组网的特点,在无线通信领域受到广泛关注.随着无线通信中多媒体业务的增加,需要在A d hoc网络中提供服务质量保证,而Q oS路由对实现网络服务质量起到非常关键的作用.文中通过分析现有的按需路由协议机制,提出一种基于能量的A d hoc网络带宽约束的Q oS路由协议.仿真结果表明该协议在中小型网络中能够较好地满足实时多媒体应用,同时具有较高的吞吐量和较低的能耗.

Mobile ad hoc network is widely concerned in wireless communication field because of its dynamically and rapidly forming a temporary network without the use of any existing network infrastructure. With the increasing use of multimedia service in wireless communication, it is need to provide QoS guarantee for Ad hoc and QoS routing is one of the key issues to do so. This paper proposes a bandwidth constraint QoS routing protocol on the basis of analysing mechanism of present on-demand protocols in ad hoc network. The simulation results show that the protocol can meet the needs of realtime multimedia＇service well in moderate and small networks with higher throughout and lower power.
