移动AdHoc是一组带有无线收发装置的移动节点组成的一个多跳临时性自治系统。由于军事和抢险救灾等方面的需要,移动AdHoc网络路由协议成为当前研究的热点之一。针对目前AODV协议改进算法较复杂,不易实现以及不能提供服务质量保证的问题,在AODV协议的基础上,提出了一种算法简单的QOS路由协议AODVQ,提供了节点不相关多径/路由并以带宽为QoS参数。通过仿真证明,该协议在分组传输率、时延和路由开销方面性能相对于AODV得到了较大的改善。
Mobile Ad Hoc network is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of preestablished network infrastructure. Because of the necessary of such as military affairs and disaster rescuing, mobile Ad hoc routing protocol becomes one of hotspots of research. But the improved algorithems of AODV are complex and difficult to implement and can't provide the guarantee of quality. A QoS routing protocol which algorithm is easy is proposed based on AODV, which provides node-disjoint mutipath routing. Its QoS parameter is bandwidth. The performance via simulations shows that it is better than AODV in packet delivery ratio,average delay and routing cost.
