Cooperative localization using MUSIC algorithm and Received Signal Strength measurements

Abstract

In this paper, we analyze the performance of cooperative localization in wireless networks using MUSIC (MUltiple SIgnal Characterization) and RSS (Received Signal Strength) measurements. In our work, we consider that the system is formed by the source, the relay antenna and the destination antenna. The relay is situated between the source and destination antenna. We propose to localize the source at the relay antenna. Signal emitted from relay to destination antenna contains information related to source location. At destination antenna, relay antenna position will be estimated and then we can estimate the source location. In each localization procedure, RSS measurements are used to estimate distances and MUSIC algorithm is applied to estimate the angle of arrival (AOA).
