Abstract

This paper presents an Energy Efficient Localization scheme for Wireless Sensor Networks (EELWSN) based on the received power of beacon signal. The operation of proposed scheme is as follows. (1) Anchor nodes are deployed evenly over the network environment in the predetermined position. (2) Sensor nodes with unknown location are deployed randomly over network environment. (3) Each anchor node broadcasts a beacon signal with location information of the anchor node. (4) Each sensor node should receive more than three beacon signals. (5) Sensor nodes estimate the relative distance between the sensor node and anchor node based on power of each beacon signal received. (6) Sensor node uses trilateration method to compute its position using the relative distances. The performance of the proposed localization scheme is evaluated in terms of performance parameters such as localization error, network lifetime, energy consumption, and cost factor.
