| 摘 要： | 能量的有限性严重限制了无线传感器网络的发展,而数据冗余问题在分层路由协议中广泛存在,网络的密度越高,数据冗余问题越严重.现介绍一种新的方法来解决这个问题.在群建立之前从网络中选取一些已分配的节点,而这些操作类似于群首节点的选取过程,这些被选取的节点将用来完成整个网络的数据融合过程.仿真结果分析表明采用了这种策略之后网络生存期延长了很多.

| Abstract: | Wireless sensor networks are constrained by limited energy resources,while data redundancy problem widely exists in layer routing protocols,and it is even worse when the network density is higher.This paper introduced a new approach in layer routing protocols to solve this problem. It first selects some evenly distributed nodes in the network before the cluster construction,which operates like selecting cluster heads. Then these selected nodes will represent the whole network to complete the data fusion pro... |
