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).

“…They actively send signals regarding each identification or sensed data. However, these signals conflict with signals from other sensors because action RFID tags cannot cooperate with other sensors [7]. The application of spread spectrum communication to active tags has been proposed in order to address this problem [8].…”

Considerable research has been conducted on systems that collect real-world information by using numerous energy harvesting wireless sensors. The sensors need to be tiny, cheap, and consume ultra-low energy. However, such sensors have some functional limits, including being restricted to wireless communication transmission. Therefore, when more than one sensor simultaneously transmits information in these systems, the receiver may not be able to demodulate if the sensors cannot accommodate multiple access. To solve this problem, a number of proposals have been made based on spread spectrum technologies for resistance to interference. In this paper, we point out some problems regarding the application of such sensors, and explain the assumption of spread codes assignment based on passive radio frequency identification (RFID) communication. During the spread codes assignment, the system cannot work. Hence, efficient assignment method is more appropriate. We consider two assignment methods and assessed them in terms of total assignment time through an experiment. The results show the total assignment time in case of Electronic Product Code (EPC) Global Class-1 Generation-2 which is an international standard for wireless protocols and the relationship between the ratio of the time taken by the read/write command and the ratio of total assignment time by the two methods. This implies that more efficient methods are obtained by considering the time ratio of read/write command.

“…Therefore, our paper will survey anti-counterfeit technologies used on the RFID tags with special focus on three papers (i.e., Juels' strengthening EPC tags against cloning [1], Duc et al's enhancing EPC tags against Traceability and cloning [2], and Pim Tuyls and Lejla Batina's RFID tags for anti-counterfeiting [3]). Furthermore, we will combine the anti-collision scheme (called DCMA [4]) with these anticounterfeit protocols. In the second section, we introduce the combined scheme of anti-collision and anti-counterfeit, and this scheme's name is A Combined Active RFID Tag Collision Resolution Protocol Against Counterfeiting (CRPAC).…”

Anti-collision in RFID will occur when multiple tags or readers transmit data simultaneously, and these data will affect each other and cannot be recognized. While anticounterfeiting in RFID occurs when a duplicated tag is used in the goods, and the reader will not be able to discover that it is a fake tag. Anti-collision and anticounterfeiting mechanisms are usually operated separately in the past, but they may have to perform at the same time in some cases. For example, when RFID-based exhibition tickets are used for entrance purpose both mechanisms will be needed simultaneously. To counter forgery attack, it is important that we have to meet not only anti-collision but also anti-counterfeiting requirement. Therefore, in this paper, we propose a suitable communication protocol of RFID tag with the function of anticollision and anti-counterfeiting called A Combined Active RFID Tag Collision Resolution Protocol Against Counterfeiting (CRPAC). In our proposed scheme, when the anti-collision mechanism is in progress, the anti-counterfeiting scheme is working along with it. Eventually, the new scheme effectively reduces the workload of RFID system and significantly decreases collision probability of the active tags.
