Modeling RFID readers deployment in three-dimensional space

Abstract

This paper presents a new algorithm for RFID deployment in 3D space. We first introduce a cubebased model to describe both the reading space and the coverage space, which can be represented by a 3D matrix. Then, an improved particle swarm optimization algorithm is proposed to implement our cube-based model in the intensive RFID reader deployment. The proposed deployment algorithm is simple and neat, by addition of two matrices. Our solid simulation results show that our cube-based model with improved particle swarm optimization algorithm is a practical scheme for the RFID coverage problem in 3D space.
