Abstract

This chapter describes the development of energy efficient and secure localization systems for wireless sensor networks (WSNs) based on anchor mobility control techniques. Towards improvement of energy efficiency and security over the network, sensors are assumed to broadcast messages in a periodic and coherent manner. Moreover, anchor is supposed to be location aware with GPS (global positioning system) receiver and capable of finding the directions of arrival (DoA) from intercepted signals using smart antennas. In each step along its trajectory, anchor communicates only with neighboring nodes having received signal strength (RSS) above a predefined threshold level. Mobility control schemes aim to explore few new nodes along with the existing ones in each subsequent anchor steps. Sensors would be able to localize themselves after receiving range (distance/angle) data from two distinct anchor positions. Accordingly, convergence speed of localization process is optimized. Simulation results corroborate its competency comparable to the existing methods.
