Energy Efficiency for Localization Accuracy by Beacon Movement Detection in Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) greatly extend our ability to monitor and control the physical world, as they have become the mark of pervasive technology. One of the main design issues for a sensor network is conservation of the energy available at each sensor node. We split the lifetime of the sensor network into equal periods of time known as rounds. Base stations are relocated at the start of a round. Energy efficient organization is forecasting the position of Mean Square Error for every node in the location. Localization is an important issue in wireless sensor networks as maintaining the location of information is indispensable in applications such as routing, target tracking. Beacons (known-location nodes) are one key approach to achieving localization in wireless networks. In this paper we propose a Beacon Movement Detection Schemes such as Location based, Neighbor based, Energy Saving Scheme, Modeling of Broadcasting Scheme, RSS-based localization and DV-hop using the distance vector exchange so that all nodes in the network get distances, in hops, to the landmarks and reliability factor information for wireless sensor networks during simulations, we evaluate the proposed schemes and examine their capability to improve the localization accuracy in events of beacon movement which improves localization.
