摘要
针对无线传感器网络分层路由协议LEACH存在的簇首节点分布不合理和网络能量负载不平衡的问题,提出了一种基于社团特性的无线传感器网络路由分簇算法(LEACH-CS)。该算法在基于社团模型构造出无线传感器网络拓扑结构的基础上,通过多跳路由选择策略,完成簇首节点与基站之间的信息数据传递。仿真实验表明,该算法和经典的分簇路由算法LEACH相比,可以达到使目标区域内传感器节点的分布相对均匀,平衡网络能耗的负载度和有效提高网络生命周期的目的。
Aiming at the problem of unreasonable cluster-heads distribution and unbalanced energy consumption in the existing Wireless Sensor Networks （WSN） clustering routing algorithm, an clustering routing algorithm （LEACH-CS） based on community structure is proposed. Based on the basis of building community structure in WSN, the algorithm completes the communication between cluster-heads and base station by using multi-hop routing selection strategy. Simulation shows that, this algorithm has the result of making the nodes distribution of WSN in target area is relatively uniform,better balancing network node energy consumption and prolonging the lifetime of network effectively.
