| In this thesis, we provide an analytical approach to evaluate the performance of anti-collision protocols in Radio-frequency identification RFID systems. The analysis is given at protocol-level using performance metrics such as the number of state transitions and clock cycles involved in the protocols' state diagrams, their power and energy consumption. Different protocols were also implemented at different level of abstractions and accurate power analysis was performed in layout level. Discussion and comparison are based on worst-case scenario that represents the process of identifying the last tag when multiple tags are simultaneously available in the system. In particular, a new protocol is proposed for performance improvement. This protocol not only provides fast tag identification mechanism but also reduces tag's power and energy consumptions as compared to other protocols that were covered in this study. |
