基于LEACH协议的簇头辅助路由算法

为了平衡无线传感器网络的负载,延长网络生存时间,针对大规模无线传感器网络场景,对低能量自适应分簇分层协议进行改进,提出一种簇头辅助路由算法。新算法采用控制信息与数据信息分离的思想,由簇头实现控制信息处理的功能,由簇内聚合节点和簇间转发节点实现数据的融合、转发功能。仿真结果显示,在大规模无线传感器网络场景下,该算法比低能量自适应分簇分层协议的网络寿命和数据接收总量均有明显提高。

Cluster head aided routing algorithm based on LEACH protocol

In order to balance the load of wireless sensor networks and prolong network lifetime, a cluster head assisted routing algorithm for large-scale wireless sensor network application scenarios is proposed by improving Low Energy Adaptive Clustering Hierarchy （LEACH）protocol. The new algorithm adopts the idea of separating the control information and data information,uses cluster head to realize the function of control information processing,and uses aggregation node in cluster and transmission node between the cluster to achieve the function of data aggregating and forwarding.Simulation results show that the network lifetime and the amount of data reception by the new algorithm are significantly better than those by LEACH protocol in largescale wireless sensor network scenario.
