A range-free wireless sensor networks localization algorithm

Wireless sensor networks have recently become one of the most interesting network technology, because it can be deployed without communications infrastructure. A wireless sensor network (WSN) has important applications such as remote environmental monitoring and target tracking. This has enabled the availability, especially in recent years, smaller, cheaper, and intelligent sensors. In this article, wireless sensor network self-positioning system and algorithm performance and evaluation criteria for classification are described, most recently on behalf of the principles and characteristics of the localization methods are discussed and proposed, and research in this area introduced.
