摘　　要：基于OLSR协议及扩展的最短路径算法,提出了综合折中跳数与带宽的一种路由计算新量度。组合MPR选择算法及路由计算新量度,设计了三种新的QoS路由方案。基于在NS-2环境中对新路由方案及OLSR原始协议进行的仿真,着重分析比较了它们的时延及分组递交率性能,探讨了带宽量度用于路由计算时对这两项性能产生的影响及主要原因,结果表明新量度能有效实现跳数少与带宽大之间的折中。Based on OLSR and the new bandwidth model and expanded shortest path algorithm,a new routing metric is proposed,which is a tradeoff between path hop count and path bandwidth.Combining MPR selection algorithm and new routing metric,three novel QoS routing schemes are proposed.Based on the simulation in NS2,we focuse on analyzing and comparing the performance （e.g,delay and packet delivery rate）for these new routing schemes and original OLSR, and discuss how the bandwidth metric effect the performance.simulation results show that new routing metric does bring a tradeoff of less path hops and wider path bandwith.
