Abstract: For solving shortcomings of the Efficient Redundant Reader Elimination（ERRE）algorithm, which has a high demand for RFID network topology and the need to set a user-defined factor, an improved redundant reader elimination algorithm based on tentative reader elimination strategy is proposed. Based on the ERRE, the tentative reader elimination strategy is merged to improve the effectiveness of the algorithm running under different topologies. The function and the weight function are deleted, and the ratio of the number of neighbors and the coverage of the reader is used as the redundant reader judgment value. Finally, the validity of the algorithm is proved by case analysis, and the simulation results of the proposed algorithm are compared with the algorithms RRE, LEO and ERRE. The experimental results show that the improved algorithm has advantages of inheriting the advantages of the ERRE algorithm and achieving the goal of not needing to consider the topology of the RFID network in practical application. Besides, the proposed algorithm does not need to set the user-defined factor which can avoid the human factors to reduce credibility of the experimental results. Compared with other algorithms, the proposed algorithm can effectively eliminate more redundant readers.
