摘　　要：随着网络负载的增加,如果不采用负载平衡机制,移动自组网路由性能将急剧下降.为改善重负载网络的性能,首先结合自组网共享无线媒体通信的特点提出了节点流量负载评估方法;接着,提出了路径代价计算方案;最后设计了具有流量感知的负载平衡路由协议LBRT(Load Balancing Routing with Traffic-aware).仿真结果表明,与AODV协议相比,LBRT有效降低分组丢包率、端到端时延且具有较低的路由开销.Under the condition of a heavy loaded mobile ad hoe network （MANET）, the routing performance without load balancing will dramatically degrades. To improve the network performance, we propose the traffic load evaluation method for the node. Such method is based on the characteristic that the wireless media is shared among the mobile devices for communication in MANET. Moreover, the path cost is defined. Furthermore, we design load balancing with traffic-aware routing （LBRT） protocol for MANET. Simulation results show that compared with AODV, LBRT efficiently reduces packet loss ratio and end- to- end delay with low overhead.
