摘要
在深入分析无线传感器网络路由协议设计目标的基础上,根据LEACH协议分层设计的思想,融入了负载平衡和簇内成树的思想,通过控制簇头之间的位置,使得簇的分布较为均匀,同时簇内节点根据节点的高度值形成一棵树,让节点采集到的数据沿着这棵树进行传输,使得簇内节点由单跳传输变成了多跳传输,很好的均衡了网络能耗。通过理论分析和仿真结果表明改进后的协议极大的延长了网络生命期,sink节点数据收集量也增加不少。
Based on analysis of design goal of WSN （wireless sensor network） routing protocol and in accordance with the idea of LEACH protocol, the load balance and the tree-making in a cluster are integrated, and by controlling the position between the cluster head, the distribution of the cluster becomes more uniform. Meanwhile the nodes in the cluster, based on its height value, form a tree, and the data collected by these nodes is transferred along the tree, the data transmission mode of cluster nodes is changed signle-hopping made to multi-hopping mode. Thus the network energy consumption is balanced. The theoretical analysis and simulation results indicate that the improved protocol could greatly prolong the network lifetime and raise the data collection quantity of sink node.
