| 摘 要： | 针对LEACH算法中簇头能量消耗过快的缺陷,提出一种基于分组的无线传感网多轮分簇路由算法LEACH-G。在分簇过程中采用分组的策略,利用信标节点signpost,在选出簇头之前承担通信任务,均衡整个网络能耗,并在簇头选取阈值中引入节点与基站之间的距离以及能量参数,降低网络能耗。仿真结果表明,与LEACH相关算法相比,LEACH-G算法能够有效降低节点10%～15%的平均能耗,延长网络生命周期,提高簇头工作效率。

| Abstract: | A grouping-based wireless sensor network multi-rounds clustering routing algorithm(LEACH-G) was proposed,which aims at the defects of the energy consumption of cluster head in LEACH algorithm.Grouping strategies are used in the clustering process,and signpost is used for communication to balance the entire network energy consumption.The factors of energy and the distance between nodes and the base station in the cluster heads selection thre-shold for reducing network energy consumption are introduced.The simulation results show that compared with correlation algorithm adout LEACH,the new algorithm can effectively reduce 10%~15% of the average energy consumption of node,significantly extend the network life cycle,and improve the efficiency of the cluster head. |
