【Abstract】 Wireless Sensor Networks(WSN) plays an increasingly important role in modern society,which is regarded as a novel technology about acquiring and processing information.However,the problem of self-localization,that is,determining where a given node is physically or relatively located in the networks,is yet extremely crucial for many applications.Based on the analysis of a great deal of recent technical reports and research results on WSN,presents common rangefree localization algorithm for WSN,and describes some improved algorithms.Introduces the directions of research in this area.更多还原
