One of the main challenges in modern anti-collision algorithms in RFID systems is to estimate the number of collided tags in each slot of identification process. This paper presents a novel solution in vogt tag estimation algorithm which is used in assigned tree slotted aloha (ATSA) method based on Chaos optimization algorithm. This method has been examined with logistic chaotic map and outcomes are compared with classical method. Simulation is accomplished with 12-bit ID which covers the full serial number bit length and the tags number are considered up to 4096 tags. Some criterions such as the number of collision slots, idle slots, and total slots are compared and simulation results show an improvement in system throughput.

In telecommunications, the capture effect is a phenomenon associated with frequency modulation reception in which two strong signals at, or near, the same frequency or channel will be demodulated. In wireless networks, a frame collision does not necessarily result in all the simultaneously transmitted frames being lost. Depending on the relative signal power and the arrival time of the involved frames, one frame can survive the collision and be successfully received by the receiver. Efficient object identification with passive RFID tags. In former works, many researches focus on the RFID anti-collision protocol only, however, less did pay special attention to the capture effect mainly to keep the design simple and cost low. Nonetheless, the capture effect occurs frequently in real deployments. In this paper, we have taken the capture effect into consideration and combined this thought to an efficient RFID anti-collision protocol, then proposed an efficient method to estimate the optimal frame length to adjust the quantity of RFID tags. After setting an optimal frame length by using the proposed method, furthermore, we obtained higher identification efficiency. RFID technology can be used for real-time recording and tracking of the learning process, which comprises real-time records of learners and their partners learning process such as experience, debate, cooperation, competition, problem solving, and other learning experiences.
