中文摘要：
无线传感器网络的最大局限是能量有限。为了高效利用网络能量、均衡网络负载,提出了一种基于能量与能耗速度的分簇算法。其中节点能耗速度是一个带有能耗预测信息的参量,利用它可以更有效地优化簇头选择与簇规模,该算法根据这两个参数来优化簇头的选择,能有效地延长节点的生存时间;同时,根据簇头节点与基站的距离、当前能量和能耗速度对簇规模进行约束和优化,进一步保证了簇之间的负载均衡。仿真实验表明改进后的算法有效地延长了网络的生存时间。
英文摘要：
Limited energy supply ability is the largest limit of WSN.In order to use energy of networks effectively and balance load of networks,a clustering algorithm based on energy and velocity of energy-consumption is proposed.Velocity of energy-consumption of sensor node is a parameter with predicting energy-consumption,it can be used to optimize choice of cluster head and size of cluster effectively.In the algorithm the two parameters are considered to optimize the choice of cluster head,it can prolong the node lifetime effectively;At the same time,the distance between cluster head and base station,energy and velocity of energy-consumption are considered to constraint and optimize the size of clusters,so as to ensure balanced load of networks.Experiment shows that the improved algorithm is effective for prolonging the network lifetime.
