An optimization framework for solving RFID reader placement problem using greedy approach

A RFID (Radio-Frequency Identification) system consists of RFID readers and tags. RFID technology uses electromagnetic fields to identify the location of the objects attached with the tag and track them continuously. The tags contain electronically stored information about the objects. The most essential requirement for setting up a RFIDenabled system is to deploy (locating and positioning) the RFID readers in order to ensure total coverage of all the RFID tags in an area. Finding an optimal number of readers required and their positions to cover all the tags is an important problem to be solved. Hence, this paper proposes a simple simulation strategy for finding optimal number of RFID readersand their positions for circular coverage using Greedy approach with 100% coverage of tags. The experimental set up and the results are explained in this paper.
