Evaluation and Exploration of Optimal Deployment for RFID Services in Smart Campus Framework

Abstract

With the application of new technologies such as pervasive wireless computing and RFID, the theoretical foundation and technical support of smarter campus are evolved rapidly. Especially, the campus security in children surveillance has been regarded as a critical issue. This work establishes a smart campus framework based on innovative RFID services. The Tabu search strategy and optimal deployment mechanism are used to find the better locations of deploying readers. In order to keep the safety of campus, this framework analyzes and designs five innovative scenarios toward children surveillance, including campus gate management service (CGMS), student temperature anomaly management service (STAMS), hazardous area management service (HAMS), campus visitor management service (CVMS) and campus equipment management service (CEMS). Then, the pervasive RFID services of five scenarios are implemented in the campus according to the demand from parents’ and teachers’ point of view. The middleware of the proposed framework adapts to collect both active/inactive RFID tags deployed around the campus, processes and filters the necessary information and events generated by the RFID reader from different locations or user rules. Finally, this work is successfully deployed and currently in use by the National Taitung University Laboratory Elementary School with more than 150 students and 30 administration staffs and faculties. Compared to traditional dense mechanisms, this mechanism has a 36 % lower deployment cost.
