Abstract: In this paper, we introduce a mobile directional anchor-based localization algorithm. Each anchor nodes can get their positions by Global Positioning System (GPS) receiver at any time. Anchor nodes move around the sensing field and broadcast beacons periodically by directional antenna. Normal nodes which want to know their positions can just listen and calculate by the information inside receiving beacons. It can lower the density of anchor nodes and decrease the computation complexity. By using the directional antenna, normal nodes can be localized in one pass of an anchor node and improve the accuracy of previous works.
