Research of wireless sensor network node localization algorithmAuthor(s): Jincheng Huang, Yaheng Zhang
This paper first introduces the basic concepts of wireless sensor network (WSN), system structure, key technology and related applications and research status at home and abroad. Secondly it introduced the wireless sensor network node localization in the process of many kinds of classic localization algorithm and the algorithm of the positioning performance of classification and evaluation standard, etc. Then without ranging localization algorithm of classic DV - Hop algorithm is carried on the thorough analysis and research. And in view of the DV - Hop algorithm in the process of positioning the insufficiency, it proposed a DV - Hop based on particle swarm optimization algorithm to improve the localization algorithm.
