%X <p>For the Aloha based anti-collision algorithm in radio frequency identification networks, tag collisions could greatly reduce the throughput of the system. If the number of tags was got, the throughput could be greatly improved. Based on maximum likelihood estimation, the proposed hybrid tag number estimation scheme combines the binary search based anti-collision algorithm and aloha based anti-collision algorithm to estimate the tag number. Simulation shows that the proposed scheme has higher estimation accuracy than the existing algorithm.</p>
