An Integrated Xbee Arduino and Differential Evolution Approach for Localization in Wireless Sensor Networks

Context aware or event based system requires location information of the event of occurrence. Sensor positioning and its location information are mandatory if a data sensed by the wireless sensor network (WSN) has to be meaningful. In cases like routing of packets of data in WSN, the dead sensor nodes should be avoided in the route. For this the location of live nodes is needed, so that the shortest and reliable routing is possible. Moreover some data require inherent location detection like forest fire detection or movement of miners in mines. So localization with better performance, with more reliability, with less computation complexity and lesser cost is much needed. This paper shows an integrated Xbee arduino and differential evolution approach for localization in wireless sensor networks, and the design of differential evolution localization algorithm for minimization of localization error. The algorithm is simple to implement and uses less control variables.
