| 摘 要： | 提出一种基于距离划分和剩余能量的无线传感器网络分簇算法,以使簇头节点分布更加合理.以网内各个节点与sink节点的距离为标准,首先将网络分为三个区域,每个区域中选择剩余能量最大的节点为簇头节点,其次在已有簇头的一跳范围外,依次取两个剩余能量最大的节点为簇头节点.经仿真验证,该改进算法在存活节点数目方面存在明显的优势.

Clustering Algorithm Based on Dividing Distance and Residual Energy for WSN |
| |
| Abstract: | A clustering algorithm is brought forward based on dividing distance and residual energy to make cluster head distribution more reasonable.The network is divided into three districts by the distance of a node from the sink node.The node whose residual energy is maximum in a district is chosen as cluster head.And two nodes out of the cluster head communication scope are chosen as cluster heads by residual energy.Then the number of existing nodes is much more than LEACH by simulation. |
