Investigation of a hybrid localization technique using Received Signal Strength and Direction of arrival

Abstract

This paper investigates a hybrid technique that uses a combined version of Received Signal Strength (RSS) and Direction of arrival (DOA) localization techniques. Simulation results prove that using the hybrid technique in one node increases the localization accuracy and provides the node with the capability of localizing other nodes by itself without any assistance from other nodes. The performance of the hybrid technique has been evaluated under both Additive White Gaussian Noise (AWGN) and Rayleigh channel conditions. Moreover, the study shows when to use the hybrid node, and where to place such node in a given environment to get the optimum results.
