Received Signal Strength (RSS) Based Channel Modelling, Localization and Tracking

Abstract

Wireless channel communication has significant importance over the past 20 years. The high data rate demand over the wireless channel increased drastically in the last decade. The design of wireless applications is for internal and external usage in which mobility of the system design is mostly considered. Path loss component, Doppler spread and multipath fading are the characteristics of wireless medium in the wave propagation model. These characteristics are affected by the system dependent parameters like mutual coupling between multiple antennas, antenna height and beam-width and also by the physical environment connecting transmitter and receiver. RSS based channel modelling, localization and tracking are presented in this paper. While designing RSS-based localization we need to select proper propagation model, which has to be accurate and best model between the RF signal and the environment. In this paper we demonstrated that RSS can be used for outdoor localization. Additionally, the presented techniques are validated using simulation results.
