“…Experiments also show that the NBA shows better behavior than the often used Binary Exponential Back-off. Jayaparavathy et al [23] suggest that the back-off time for each contending node can be modified by retrieving information obtained from transmitting stations (delay from the contending nodes) thereby getting higher throughput and shorter delays.…”

Abstract-Active Radio Frequency Identification (A-RFID) is a technology where the tags (transponders) carry an on-board energy source for powering the radio, processor circuits, and sensors. Besides offering longer working distance between RFIDreader and tag than passive RFID, this also enables the tags to do sensor measurements, calculations and storage even when no RFID-reader is in the vicinity of the tags.In this paper we introduce a medium access data communication protocol which dynamically adjusts its back-off algorithm to best suit the actual active RFID application at hand. Based on a simulation study of the effect on tag energy cost, readout delay, and message throughput incurred by some typical back-off algorithms in a CSMA/CA (Carrier Sense Multiple Access / Collision Avoidance) A-RFID protocol, we conclude that by dynamic tuning of the initial contention window size and back-off interval coefficient, tag energy consumption and read-out delay can be significantly lowered. We also present specific guidelines on how parameters should be selected under various application constraints (viz. maximum readout delay; and the number of tags passing).

Abstract-Active Radio Frequency Identification (A-RFID)is a technology where the tags (transponders) carry an onboard energy source for powering the radio, processor circuits, and sensors. Besides offering longer working distance between RFID-reader and tag than passive RFID, this also enables the tags to do sensor measurements, calculations and storage even when no RFID-reader is in the vicinity of the tags. In this paper we study the effect on tag energy cost and read out delay incurred by some typical back-off algorithms (constant, linear, and exponential) used in a contention based CSMA/CA (Carrier Sense Multiple Access/ Collision Avoidance) protocol for A-RFID communication.For the type of A-RFID scenarios considered, where the number of tags is varied as well as how fast they pass a reader, simulation results show the importance of selecting the correct length of the Initial Contention Window (ICW) and the algorithm coefficient based on the number of tags.The study also indicates that by dynamically selecting the proper back-off algorithm coefficients (based on the number of tags), viz. the initial contention window size and the back-off interval coefficient, the tag energy consumption and read-out delays can be significantly lowered compared to using a static back-off algorithm.
