摘要:

在无线传感器网络中,由于能量耗尽以及恶劣环境的影响,传感器节点容易出现故障导致网络不连通。为此,针对无线传感器网络中的拓扑修复问题,总结和分析近年来相关的主要方向和研究成果,同时根据网络故障规模的不同对小规模故障和大规模故障的网络修复算法进行 分类总结以及优缺点分析。此外,从算法触发条件以及实现角度等方面对修复算法作进一步分类,并指出当前研究的不足和未来的改进方向。

Abstract:

Sensor nodes in wireless sensor network(WSN) are prone to failure due to energy depletion and the effects of harsh environments.The failure of the node will make the network to be disconnected.This paper studies connectivity restoration of WSN,analyzes and summarizes the related main direction and the research results in recent years.According to the scale of network failure,the restoration algorithms are divided into two types,one is for small-scale failure and the other is for large-scale failure.In addition,the repair algorithms are further classified from other aspects,such as triggering conditions,realization viewpoint,and etc.Finally,the shortcomings of the current research and future research directions are pointed out.
