摘要
在WSN(Wireless Senor Network,无线传感器网络)中的分级路由算法中,如果簇头仅仅能够进行单跳通信或者多跳通信,都会造成网络负载不均衡以及簇头能量消耗过快的问题出现。针对这一问题,文章提出了一种改进的基于LEACH-C(Low Energy Adaptive Clustering Hierarchy Centralized,低功耗自适应集中分层型)算法的簇间路由(Cluster Routing based on LEACH-C Algorithm,简称CRLA)算法。该算法通过距离阀值来控制簇头是进行单挑通信还是多跳通信。仿真分析表明,CRLA算法能够实现网络负载的均衡以及减少簇头能量的消耗,从而实现网络生存时间的延长。
In the hierarchy routing algorithm of wireless sensor network, cluster head single hop or multiple hops communications wil lead to imbalance of network balance and too fast energy consumption. To solve the problem, a cluster routing based on LEACH-C algorithm is proposed. In CRLA algorithm, threshold is used to control the communication style. Simulations demonstrate that CRLA algorithm can balance network load, and reduce the energy consumption of the cluster node.
