An RFID network consists of a set of tags and readers. The cost and the number of tags covered directly depend on the number of readers. So, finding optimal number of readers and their positions to cover all tags is one of the most important issues in an RFID network. In this paper, the authors have proposed a reader placement technique in a departmental store equipped with RFID network using Particle Swarm Optimization (PSO). The proposed algorithm finds minimal number of readers along with their position with 100% coverage of tagged items. Simulated results also show the algorithms effectiveness in achieving the optimal solution.
