摘　　要：提出了一种移动自组织网络(MANET)中均匀分配业务量、减轻网络局部拥塞的多路径负载均衡方法.通过基于Bloom滤波器的流量检测方法获得每个节点的负载,在源节点进行负载均衡.多路径负载均衡方法路径选择标准为链路生存时间、端到端时延和转发路径当前的负载情况.通过仿真对其性能进行了衡量和分析,仿真结果表明,该方法在分组投递率、端到端时延和所需的控制包开销方面优于传统多路径机制,该方法适用于节点密度较小的场景.In mobile Ad hoc networks（MANET）,a multi-path load balancing mechanism was proposed in order to distribute the traffic evenly into the network and alleviate partial congestion.Load balancing method was realized at the source node after detecting the current flows in each node by using Bloom filter.The estimated link lifetime,the end-to-end delay and the existing traffic along the forwarding paths were used together as the routing metric of multi-path load balancing mechanism.The proposed multi-path load balancing mechanism was evaluated and analyzed through simulations,which showed that the performance was better than the traditional multi-path routing mechanism,such as the packet delivery ratio,the end-to-end delay and the control traffic;the results also showed that multi-path load balancing mechanism suited for the scenario with small node density.
