摘　　要：在分析ad hoc网络的单播QoS路由问题的基础上,本文提出了一种新的分布式QoS路由算法——LMLAR(local multicasting location-aided routing)算法。LMLAR算法最关键的思想是利用了“本地多播”机制和位置信息选择路由。仿真结果表明:LMLAR算法能够以较小的路由消息开销取得较高的路由成功率,具有比TBP算法更好的性能,适合于ad hoc网的高度动态的环境。On the basis of analyzing the problem of unicasting QoS routing in the ad hoc networks, a new distribute QoS routing algorithm,LMLAR(local multicasting location-aided routing) algorithm, has been proposed. The key idea of the proposed algorithm is to utilize the 搇ocal multicast?mechanism and the location information to select the route. The simulation shows that the LMLAR algorithm can acquire the higher routing success ratio and the lower message complexity than TBP algorithm. So the LMLAR algorithm is feasible to highly dynamic environments in the ad hoc network.
