Analysis of mobile beacon aided in-range localization scheme in ad hoc wireless sensor networks

In this paper, We mathematically model the In-Range localization scheme in the presence of a Mobile Beacon. In the In-Range localization scheme, a sensor with unknown location is localized to a disc centered at the position of the beacon, if the sensor under consideration can successfully decode a transmission from the beacon. In our approach a Mobile Beacon guided by a mobility model is used to generate the virtual beacons, there by eliminating the need to deploy static beacons that are required in the classical InRange localization scheme. For analysis, we consider a Mobile Beacon guided by the Random Way Point (RWP) mobility model with In-Range localization scheme. The main contribution of this paper consists of mathematical models for the In-Range localization parameters in the presence of a Mobile Beacon guided by the RWP mobility model.
