Abstract

In absence of line-of-sight (LOS) signal, localization is a real challenge since multi-path effect takes place due to reflections and/or scattering of signals. In this paper we have assumed that there are few anchor nodes present in the network which broadcast ultrasonic and electromagnetic signals with their known positions. Based on receiving those ultrasonic signals and using received signal strength of the electromagnetic signals, a localization technique has been proposed for finding position of other sensor nodes. On the assumption that a signal may be reflected at most twice before reaching a node, our technique provides on an average 67% reduction of the area of the zone in which the sensor node will be bound to reside.
