摘　　要：为解决MANET中网络拥塞导致的网络时延增大和吞吐量下降的问题,提出了一种新的基于信道负荷感知的负载均衡路由协议CLB-DSR(channel load based-dynamic source routing)。该协议中,节点通过监测信道的繁忙比例预测信道的负荷,完成对信道状态的感知,中间节点根据感知的信道状态决定是否允许路由。CLB-DSR协议对网络负载的映射考虑了邻居节点的负荷,对网络状态的描述全面而准确,CLB-DSR路由协议只需监测信道的状态,一定程度上减少了负载信息在网络中传播带来的网络开销。仿真表明,该路由协议在没有增加网络开销的情况下,有效地提高了网络的吞吐量,降低了平均端到端时延。To solve the problems of network congestion leading to high end-to-end delay and low throughput in MANET（mobile ad hoc network）,a new routing protocol with load balance based on channel load—CLB-DSR（channel load based-dynamic source routing）was proposed.In this protocol,the channel state was perceived by monitoring the channel busy proportion.Intermediate nodes decided whether to allow routing according to the channel state perceived.The mapping of CLB-DSR protocol took the overload of neighbor nodes into account,so its description of network state was comprehensive and accurate.CLB-DSR protocol simply monitored the occupancy of the channel,so to some extent it reduced the network load caused by overload formation transmission in the network.Simulation results show that the new protocol improves the network throughput and reduces the end-to-end delay effectively without extra route overhead.
