Robustness optimization for solving the deployment of RFID readers problem

Abstract

Radio Frequency identification (RFID) is a new technology that can identify objects without physical contact using radio frequency waves. The RFID system consists of a Tag attached in objects (people, plants, equipments, etc) and contains a unique information. The tags are identifiable by a Reader, when they're located in its interrogation range. The deployment of readers problem with the aim to optimize several objectives by focusing on the coverage, the number of deployed readers and their interference. In practice, the optimal solutions to the deployment readers problem can significantly degrade because of uncontrollable variations on the parameters. In this work, we introduce for the first time the robustness multi-objective optimization for solving the deployment of RFID reader problem. Therefore, we reach the robust solutions that are optimal and insensitive to uncertainties on the optimization parameters.
