Experimental evaluation of read performance for RFID-based mobile sensor data gathering applications

Abstract

We consider RFID-based sensing applications enabled by passive or semi-passive tags and mobile devices equipped with readers. We experimentally investigate the feasibility of such RFID-based mobile sensor data gathering applications, focusing on UHF RFID devices and indoor scenarios. We examine the impact of various factors, including reader mobility, multiple closely located tags and other key related metrics. Our measurement results suggest the feasibility of using RFID for such applications.
