Characterization of the on-body received signal strength indication considering different propagation environment

Abstract

A method based on the received signal strength indicator (RSSI) for the characterization of wireless communication between on-body sensors in different propagation environments is presented in this paper [1]. The CC2431 sensors are employed to do the experimentation in indoor and outdoor environments in this study. These sensors are being used typically in ubiquitous sensor networks (USN) providing PHY layer functions for IEEE802.15.4 standard. They use a radio frequency (RF) transceiver for wireless communication at the 2.4GHz Industry Science Medical (ISM) band. Six on-body receivers and one transmitter replicating a typical body centric wireless network are used for the measurement campaign and impact of the varying environment on the RSSI value is analyzed.
