Performance Analysis of RFID Tag Detection with Smart Antenna Using Adaptive Power Allocation
Keywords:
RFID, Adaptive Algorithm, Smart Antenna, Reader, Tag , Tag Detection & Power AllocationAbstract
This paper proposes a novel approach to optimize the tag detection, coverage problem and power allocation issues of the RFID reader and tags. We have investigated the effects of variable localization of RFID tags from reader and power loss, inefficiency and distance constraints caused due to equal power allocations to the tags. As an improvement to the situation, implementation of adaptive algorithm has been proposed which could estimate the variable distances of tag from the reader and distribute power to tags based on this calculation. We have proposed the implementation of smart antenna instead of traditional antenna in RFID system addressing the above cited problems. Results from mathematical analysis and simulation has been included which demonstrate that our proposed scheme shows a significant improvement over the traditional approaches of tag detection and power allocation techniques of RFID systems.
