针对无线传感器网络分簇路由协议中因簇间路由产生的簇头能量消耗不均衡的问题,提出一种簇头负载均衡的分簇算法。此算法在产生非均匀分布的簇头的基础上,建立由簇头组成的骨干传输网络的簇间转发路径,计算簇头的中转数据量。传感器节点在选择簇头时进一步考虑簇头的中转数据量,实现簇头的负载均衡。仿真实验结果表明,该路由协议有效地平衡了簇头的负载,并显著延长了网络的生存时间。
Aiming at the unbalanced energy consumption of cluster heads caused by inter-cluster routing in the wireless sensor network clustering routing protocol, a clustering algorithm based on cluster head load balancing is proposed. Based on the generation of non-uniformly distributed cluster heads, this algorithm establishes the inter-cluster forwarding path of the backbone transmission network composed of cluster heads and calculates the amount of transit data of the cluster heads. Sensor nodes in the choice of cluster head to further consider the cluster head of the transit data to achieve cluster head load balancing. The simulation results show that the routing protocol effectively balances the load of cluster heads and significantly prolongs the lifetime of the network.
