The Current Situation and Prospect of Localization in Wireless Sensor Network

Node localization which is determining where a given node is physically or relatively located is extremely crucial for most of the applications in wireless sensor network. In this article, we review and describe the taxonomy and fundamental localization methods. The current research in WSN localization algorithms are introduced, analyzed and concluded. The point is that no single algorithm performs best, there is significant room for improvement in tradeoff between high accuracy and low expense, energy cost. At last, we proposed the idea of combining many algorithms to make it more accurate and applicable and using artificial intelligence (AI) in mobile localization.
