摘要:

针对无线传感器网络能量空洞问题,通过对具有节点均匀且呈环状分布的WSN相关模型进行了分析。并在此基础上,将能量空洞问题转化为不同发射半径下,能量消耗值最大节点的问题,从而确定了具有不连续、不可导、多峰值特点的优化目标函数。最终采用CoDE算法求解该优化问题,并通过仿真实例验证了,该方法的正确性与可行性。

Abstract:

For the problem of energy hole in the wireless sensor networks (WSN),this paper analyzes the relevant models of the WSN in which the nodes are distributed uniformly in a ring.Based on the analysis,we transform the energy hole problem into the problem of finding the maximum energy consumption of the nodes with the largest energy consumption of different emission radius.The objective function with discontinuous,un-derivable and multi-peaks characteristics is defined.Finally,this optimization problem is solved using the composite DE (CoDE) algorithm.The correctness and feasibility of this method is verified by simulation experiment.

Key words: differential evolution;wireless sensor network;energy hole;optimization;objective function
