Research of WSN Localization Algorithm Based on Moving Beacon Node

With the development of communication and sensor technology, wireless sensor network (WSN), which integrate data acquisition, processing and transmission, communication, cause the attention of people. Limited by node´s energy, we should consider node localization algorithm, when study wireless sensor network; There are two kind of localization algorithm: based on range finder technology and without range finder technology location algorithm, in this paper, based on the classical DV hop algorithm, we study a node localization algorithm based on moving beacon node.
