    Abstract

    One of problems that we faced for Radio frequency identification (RFID) systems is that the collision between tags which lowers the efficiency of the RFID systems. One of the popular anti-collision algorithms is ALOHA-type algorithms, which are simple and have good performance when the number of tags to be read is reasonable small. In this paper, an enhanced dynamic framed slotted ALOHA algorithm for RFID is extended to a more general close form, hence reference [9] becomes only one special case described in our paper. The improved ALOHA algorithm for RFID tag identifications has much larger capacity to handle the cases when the tag numbers increasing largely while every frame keeping the optimum system efficiency 35.5%. Simulation results show that the proposed algorithm improves the efficiency nicely in comparison with the conventional algorithms keeping >80% as the previous paper shown
