摘　　要：针对水文监测系统无线Mesh网络中传输数据流量大、路由节点固定的特点,提出基于路径权值的多信道负载均衡路由算法,通过对每条链路容量进行预测,以Dijkstra准则选择最优路径,达到对负载流量均衡分配、提高网络吞吐量的目的。OPNET仿真结果表明:新算法使信道资源得到充分利用,比AODV算法网络吞吐量提高了3倍,具有更小的传输延迟。For the characteristics of heavy traffic and fixed router node in wireless mesh network of hydrological monitoring system, a multi-channel load balance routing algorithm based on path weight is proposed. By forecasting capacity of each link and choosing the opti- mal path with Dijkstra criterion, the load traffic is balanced and network throughput is in- creased. The simulation result on OPNET shows that the new algorithm is three times high- er than AODV for network throughput, has smaller propagation delay and makes full use of the channel resources.
