摘要
对于目前移动自组网(MANET)中大多数路由方案没有考虑中间节点处的排队延迟和竞争延迟,导致较大端到端延时的问题,提出一种基于移动性和Qos感知的任播路由方案(MQAAR).MQAAR使用改进的动态源路由(DSR),设计节点稳定性模型、Qos拥塞模型,通过任播方式,优化MANET中路由发现和路由维护方法 .仿真结果表明,相比ACAP、DSR和ALBRS,MQAAR在控制开销、数据包传输率和平均端到端延迟方面具有更高的性能.可以更好地应用于MANET中,具有一定的实际应用价值.
Aiming at the problems of queuing delay and contention delay at the intermediate node are not taken into account for route selection in most routing schemes with a higher end-to-end delay in Mobile Ad hoc Network(MANET).A Mobility and Qos Aware Anycast Routing(MQAAR)scheme is proposed.The improved Dynamic Source Routing(DSR),node stability model and Qos congestion model are used in MQAAR to optimize route discovery and route maintenance in the mode of anycast.The simulation results indicate that compared to ACAP,DSR,and ALBRS,MQAAR has higher performance in control overhead,packet delivery ratio and average end-to-end delay.It can be better applied in MANET,which has some practical value.
