An Improved Anti-collision Algorithm Based on JDS

With the emergence of active tags and RFID technology used in the fast-moving objects, readers need urgently to read and write tags in limited time. Anticollision algorithms resolve the problem of a number of tags at the same time to communicate with the reader. Traditional anti-collision algorithm is to minimize recognition time and improve search efficiency under the conditions of maintaining a certain complexity. In this paper, we propose an improved anti-collision technique based on IPA and JDS algorithms. The improvement is achieved thanks to use jumping-back strategy. This latter reduces considerably the responding tag’s numbers and therefore, decreases the probability of bit’s collision. The simulation results shows, the reduced IPA anti-collision algorithm reduce frequency and the number of bits of the reader queries and label response significantly.
