Relative-localization identification of random distributed wireless sensor network nodes

Localization services are one of the most important services provided by wireless sensor networks. In this paper, a relative-localization identification of random deployed non-anchored nodes will be presented. Based on relative RSSI information, the system can identify which sensor nodes are placed in locations planned on map. The method can let user put any nodes anywhere (random distributed), and the nodes will locate themselves without knowing the coordinate (absolute or relative) beforehand. The algorithm and experimental verification of this method will all be detailed in this paper.
