    Analysis of mobile beacon aided in-range localization scheme in ad hoc wireless sensor networks
    (2006) Srinath, T.V.; Katti, A.K.; S, V.S.
    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 In-Range 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. Copyright 2006 ACM.
