Teaching Reform of WSN Laboratory Class based on a Virtual Simulation Platform

Abstract

Wireless Sensor Networks (WSNs) are considered as one of the most rapidly developing technologies in recent years. The WSN course, as a core curriculum of the Internet of Things (IoT) major, also plays an important role in higher education teachings. However, the inadequate facilities, equipment and spaces have been main constraints of universities’ WSN laboratory classes. In this paper, we designed a specific situation and scene for smart home, one of the commonly used applications of WSN, and developed a Virtual Simulation Experimental Platform (VSEP) based on Unity 3D engine, aiming to enhance students’ learning interest and improve their practical skills. In particular, we firstly analyzed the current limitations in WSN experimental teachings, with design concepts and objectives and experiment teaching content of VSEP introduced thereafter. In addition, we discussed systems architecture and functions design, and experimental methods and steps. Finally, an anonymous survey was utilized to examine the teaching reform result. The study showed that most students have found the virtual platform helped them understand the theoretical concepts and experimental processes better, and is an effective way to learn the course.
