基于虚力的移动节点的无线传感网络空洞修复算法
Virtual force mobile node based algorithm to heal holes in wireless sensor networks
摘要
Abstract
The emergence of holes in the region of interest(RoI)is unavoidable due to the inherent properties and environ⁃mental factors of WSNs. Therefore,the virtual forces⁃based localized movement hole healing(VF⁃LMH)algorithm is proposed in this paper. The VF⁃LMF algorithm is operated in two distinct phases:hole detection and hole repair. The VF⁃LMH algorithm in the phase of detecting hole is to discover the holes,hole center location and size by the localized protocol of Gabriel graph (GG) of network. In the hole repair phase,the hole healing area (HHA) is confirmed first,and then the nodes in HHA are moved according to the virtual force for the hole healing. The simulation results show that the proposed VF⁃LMH algorithm is able to detect and heal the holes. Compared with the similar algorithms,the cost for hole healing of VF⁃LMH algorithm is lower because it has less moved nodes and shorter total moving distance.关键词
