In most applications, the physical location of the guide to the sensor node is a basic requirement, however, due to the large number of sensor nodes, randomly distributed, and the software and hardware resources are limited, so study effective positioning algorithm to determine the location of each node has an important theoretical significance and practical value. Access to large amounts of literature on the basis of the lessons do an overview of the wireless sensor network-based positioning technology, wireless sensor networks, highlights several typical distributed positioning algorithm principle and characteristics, including Amorphous , APIT, Centroid, DV-Hop, RSSI, etc., its Matlab simulation environment simulation analysis, and compare the positioning accuracy of the various algorithms and error. Keywords: wireless sensor networks, localization algorithm, Matlab, simulation analysis I. INTRODUCTION Positioning of wireless sensor networks is the wireless, self-organizing network to provide location information of nodes in the network in some way, self-organizing network localization process can be divided into self-positioning and targeting node node positioning itself to determine the coordinates of the information network
