DEVELOPMENT OF SMART CAMPUS APPLICATIONS BASED ON WIRELESS TECHNOLOGIES USING OPEN-SOURCE PLATFORMS

Malaysian National Center for Education estimates that students' enrolments will increase to 17.2 million by 2028. The conventional way of managing things around campus work can be improved by applying the smart campus concept. This study showcases the potential smart campus applications with different wireless IoT technologies and their application; LoRa for Internet of Bicycle (IoB), Sigfox for water quality monitoring, IEEE 801.11p for campus active safety application, and NB- IoT for remote mangrove conservation. The prototypes consist of various sensors and online dashboards to demonstrate the open-source IoT ecosystem. For IoB, a 0.5 km radius centered at LoRa gateway's location, proved reliable for real-time e-bicycles location monitoring. It offers locking system security to avoid bicycles steal. The SigFox-based water quality monitoring system received signal performance is adequate (RSSI -80 to - 90 dBm) with a tower location approximately 3 km from the lake area. For active safety applicationbased on IEEE 801.11p, communication of braking force, car speed, and position of cars ahead of an obstacle make this application feasible to improve road safety around campus, with the real implementation expected to be achieved in the next five to ten years. Lastly, the application of remote mangrove conservation monitoring using NB-IoT on LTE mobile network from Celcom as an independent wireless platform. It allows researchers and students from the university to use this application for their research on sustainable conservation at remote mangrove sites worldwide. The results have shown that all the wireless IoT is promising for future smart campus deployment.
