针对移动自组织网络中负载分布不均所导致的网络性能恶化问题,提出了一种基于分组转发行为不确定度量的网络负载计算方法,并以此为基础提出了负载均衡按需路由协议,通过监测分组转发过程中的行为变化特征,采用信息熵的形式对其进行量化和度量,并在路由发现过程中利用节点负载监测信息合理规避网络热点区域,以达到网络负载均衡分布的目的。仿真结果表明,基于负载均衡策略的路由协议能够有效提高分组递交成功率,降低分组传输延迟。
To solve the network performance deteriorating problem caused by uneven load distribution in mobile Ad hoc networks, this paper presents a network load measurement algorithm as the basis for a load balanced routing protocol, which monitors the behavior change characteristics in the process of packet forwarding, using information entropy to measure and quantify them, and using load-monitoring information of network nodes to reasonably avoid network hotspot areas in routing process, to achieve a balanced distribution of network load. Simulation results show that the proposed strategy can effectively improve the packets delivery ratio and reduce the end-to-end packet delay.
