摘要 为建立一个高效节能的路由环境,在分析PEGASIS(Power-Efficient Gathering in Sensor Information System)的基础上,提出一种改进的成链方法——节点分区成链型PEGASIS算法(D-PEGASIS)。该算法通过对节点按位置分组成链的方法,减少网络中长距离信息传输的次数及能量消耗。仿真实验结果表明,该算法对PEGASIS有较大改进,延长了节点生命周期,且节点之间能量消耗非常均匀。 Formulation of energy efficient protocols is of utmost importance for Wireless Sensor Network（WSN） because of energy constraints of sensor nodes.PEGASIS（Power-Efficient Gathering in Sensor Information System） is one of low energy algorithms for wireless sensor networks.It constructs the chain by using greedy approach.This paper divides the chain into several parts.This method helps enhance network performances by reducing the inter-nodal transmission distances.Simulation results show that the improved algorithm has a higher efficiency of energy utilization.
