Message-Efficient Localization in Mobile Wireless Sensor Networks

Abstract

Locations of sensors in wireless sensor networks (WSNs) play a vital role in many applications. Regarding the mobility of the nodes in some of the applications, it is necessary to have a localization algorithm that can support the mobility of nodes. In this paper a demand-based algorithm has been presented which uses information of messages for update their tables so they can help to localize the unknown nodes. This technique suggested method that called ELoc(Efficient Localization) has been able to present a higher speed and range of success, by reducing the sent messages and consequently reducing the energy consumption quite significantly.
