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