A2L: Angle to Landmarks Based Method Positioning for Wireless Sensor Networks
— Thanks to recent technological progress, autonomous wireless sensor networks have experienced considerable development. Currently, they are used in the areas of health care, environment, military etc. For a number of sensor-based applications, the knowledge of the positions of sensors is required or, at least, preferable. In this paper, we propose a new method to locate a large number of nodes in wireless sensor networks where only a subset of them are landmarks (i.e., know their positions). Our method is AOA-based (Angle Of Arrival) and it is called A2L (Angle to Landmark). Compared, via simulations, to previous methods such as APS and AHLoS, A2L considerably increases the number of located nodes with accurate precision while using a smaller node degree. Keywords- wireless sensor networks, localization, Angle of Arrival, trilateration.
