Research And Implementation Of Positioning Technology Based On Wireless Sensor Network

In recent years, in location based services promotion, the positioning technology has received the domestic and foreign researchers' enormous attention. At present, the perfect positioning technology like GPS localization technology, confined to its positioning time, pointing accuracy as well as complex environment factor, is unable completely to be competent the omni-directional localization need, especially in indoor environment, it nearly can do nothing. Therefore, the related research of high accuracy localization technology is paid much attention, many research devotes to the high accuracy indoor localization goal by using small, light and inexpensive sensors to set up wireless sensor network, even by using sensor fusion technology.This article is for the purpose of making some related discussions and research of localization technology based on wireless sensor network, embarks from the introduction of latent application of localization technology, studies some key localization technology in wireless sensor network, and with the help of our laboratory project, the indoor positioning system is designed in detail, finally, a new positioning system design proposal is proposed. The paper mainly involves the following several aspects:1. The latent application prospect of localization technology is discussed completely, and the existing mobile localization technology and the indoor localization technology are introduced exhaustively.2. The research development condition, the main characteristics, the merit, the...
