基于优化簇半径的WSNs非均匀分簇路由

Uneven clustering based on optimal cluster radius for WSNs

为了有效解决无线传感器网络分簇路由协议中,靠近SINK节点的簇头因转发大量数据而过早耗尽能量,提出了一种优化簇半径的非均匀分簇路由协议(UCOR),其核心思想是通过优化簇半径对无线传感器网络进行合理分簇,使靠近SINK节点的簇规模小于远离SINK节点的簇。仿真实验结果表明,与EEUC和LEACH等路由协议相比UCOR路由协议有效地均衡了节点能量消耗,显著地延长了网络生命周期。

An uneven clustering protocol based on the optimal cluster Radius（UCOR） is proposed to avoid the nodes colsed with sink will soon run out of energy.This protocol optimizes the distribution and size of cluster by using the optimal cluster radius.The cluster size grows gradually as the distance between the cluster head and sink increase and closes to the optimal cluster size as much as possible.The experiment results show that UCOR balances the energy consumption of nodes effectively and extends the network life-cycle significantly compared with LEACH and EEUC.
