LITeTag: Design and Implementation of an RFID System for IT-based Port Logistics

Logistics has grown dramatically, especially where identifying, locating, or tracking objects in ports are important, because ports are gateways to extended markets. In this paper, we analyze the new requirements of port logistics after a brief introduction and present a system prototype. Then we describe the design and implementation of an RFID system for IT-based port logistics. Our solutionnamed Logistics Information Technology electronic Tag (LITeTag) consists of three parts: a smart tag, a smart electronic container seal, and an RTLS system. These offer a complete range of port logistics services that cover the entire port environment. Also, our system design focuses on fourparts: 1) the standard compliance with the ISO, 2) conservation of energy to extend the live of the tags for as long as possible, 3) a high identification rate in the presence of multiple tags, and 4) the fastest possible tag response time. A performance evaluation of the system is also included inthe paper.
