Evaluation of RFIDSim - a Physical and Logical Layer RFID Simulation Engine

Radio frequency identification poses a number of research challenges, such as interference mitigation, throughput optimization and security over the RF channel. In this paper we investigate to what extent the physical and logical layer simulation engine RFIDSim can be used to evaluate RFID system performance. Our analysis compares simulation results against measurements with RFID equipment and theoretical predictions. Our analysis focusses on timing and medium access behaviour and signal strength modeling in RFIDSim.
