基于无线传感器离散网络模型的 Bounding Box定位算法研究
STUDY OF BOUNDING BOX LOCALISATION ALGORITHM BASED ON WIRELESS SENSOR DISCRETE NETWORK MODEL
摘要
Abstract
Bounding Box algorithm is a typical node localisation algorithm based on discrete network model in wireless sensor network (WSN).To overcome its disadvantages in low localisation accuracy and coverage rate , we propose an improved localisation algorithm which employs the virtual anchor nodes strategy .First, the unknown nodes will calculate their own coordinates by making use of the anchor nodes within their communication range .Secondly , the located unknown nodes will upgrade themselves as the virtual anchor nodes according to the promotion strategy selectively .Finally, those nodes which are unable to locate themselves will use the virtual anchor nodes to get their own location.Besides, the establishment of the network node model with double radius based on discrete network model further restrict the location of the unknown nodes .Theoretical analysis and simulation result all show that the proposed algorithm can effectively improve the localisation accuracy while significantly raise the coverage rate of localisation .关键词
