基于移动无线传感器网络的k-阶覆盖算法

摘要

在移动无线传感器网络中,传感器节点可能由于自身移动、能量损失、物理损坏、错误和故障等因素的影响,从而出现覆盖漏洞的情况,继而导致网络覆盖效率低下。本文就此设计了一个新的移动无线传感器网络覆盖算法,基于分簇的方式,而且能够实时监测网络中出现的覆盖漏洞,并迅速进行修复。仿真结果表明,对于移动无线传感器网络,该算法不仅能够实现所期望的覆盖均匀度,还能够增加覆盖面积,提高网络覆盖率,而且性能要优于VFA。%In mobile wireless sensor network,considering that sensors node may be in the intersection of no-signal area due to the causes of its move,the energy loss,physical damage,errors,failures and so on,leading to less effect of the network-covering.This paper designed a new algorithm for mobile wireless sensor network coverage,clustering-based approach,can monitoring the network coverage holes in real-time and quickly repaired.Simulation results show that for mobile wireless sensor network,the algorithm can achieve the desired uniformity of coverage,increased coverage,improved network coverage,and its performance is better than VFA.
