Localization Algorithm of Anchor Nodes in Wireless Sensor Networks Based on Local Distributed Optimization
摘要
Abstract
Since there is a problem of sparse distribution of anchor nodes in the irregular wireless sensor networks, and some nodes may cause larger errors in localization, a local distributed optimization algorithm is proposed based on Anchor Selection algorithm. The ideology of "the localization of the nodes in local area before that in the whole network" is employed. The hop distance between nodes is optimized and some nodes obtained by reasonable estimation aer prommed as the anchor nodes in the localization process to provide more information for subsequent localization of the unknown nodes. Experimental results show that the algorithm has strong fault tolerance and can get better effect of localization in dealing wuh irregular networks.关键词
