Analysis of Factors Affecting Anti-Collision Performance of RFID Based Asset Tracking System In WSN Platform

Abstract

In an RFID system, a reader identifies a set of tags over a shared wireless channel. When multiple tags communicate with the same reader simultaneously, some of the packets will be lost due to collision of data, thus jeopardizing the integrity of the RFID system. In this project, the performance of the anti - collision mechanism was investigated in the real environment by identifying the MAC parameters and external factors that could affect the system performance using the Design of Experiment (DOE) method and Analysis of Variance (ANOVA) statistical tools. The experimental results reveal that the performance of the designed remote asset tracking system’s anti-collision mechanism is influenced by random slot delay, distance, and clear channel assessment.
