一种基于IDV-Hop算法的改进定位机制
An Improved Localization Scheme Based on IDV-Hop for Large-Scale Wireless Sensor Networks
摘要
Abstract
It is extremely urgent to establish and maintain low cost and high efficient localization schemes for real-time large-scale surveillance systems. An improved DV-Hop based localization scheme IDV-Hop embedded in WLS ( weighted least square) method,accompanying with HTC scheme,is proposed for the purpose of surrounding surveil-lance,object localization for early warning,rescue operations and restructuring plan et al. Two critical parameters, correction coefficient kc and weighted coefficient wNx,i,are introduced into IDV-Hop scheme to improve location per-formance. And then,NS-2 simulations demonstrate that analysis results match well with simulation results. Besides, behaviors of IDV-Hop is improved largely relative to other DV-Hop based schemesfor large-scale sensor networks.关键词
