%X A joint anti-interference optimization algorithm for multiple readers is proposed, which integrates random access and power control strategies. Firstly, considering the effects of access probability, transmitting power and channel selection on the signal-to-noise ratio (SNR) of the reader, the anti-interference problem of multiple readers is modeled as a mixed integer programming problem. Secondly, the generalized Benders decomposition method is used to decompose the algorithm into an easy-to-solve primal problem and a master problem of binary programming. It is proved that the algorithm converges to the global optimal solution. Finally, the simulation results show that the algorithm outperforms the existing schemes in tag recognition rate and fairness.
