针对带状传感网采用分簇拓扑能有效管理网络,但负载不均衡容易导致节点能耗不均而影响网络寿命的情况.提出一种带状网负载均衡路由协议(SWSN—LBR)完成网络划分及汇聚节点选择.该协议仅需分簇的节点数和剩余能量信息,采用二分法快速确定出横向网络分区的最佳能量平衡分界点.仿真结果表明,与最小能量成本树(MECT)路由相比,该协议能有效提高网络平衡性,延长网络生存时间.
Strip-based wireless sensor network (WSN) in cluster topology is efficient for network man- agement, but its load imbalance trends towards unequal energy consumption and short network lifetime. Regarding a strip-based WSN with multi-Sinks in data gathering applications, a strip-based WSN load balance routing (SWSN-LBR) protocol for network partition and sink selection was proposed. SWSN-LBR only needs the node number and residual energy information of cluster, uses the dichotomy to rapidly search the optimal energy partition position in horizontal dimension. Simulation result shows that compared to MECT (minimum energy cost tree) routing protocol, SWSN-LBR can effectively balance the network energy consumption and prolong the network lifetime.
