摘要
En 中文
Formal learning on networking basics can reduce motivation and expectations for students who aim to become future professionals on wireless networks. To address this shortcoming, this paper presents an educational methodology to enhance learning by conducting cases studies on Wi-Fi network design. The proposed methodology is supported by a new educational simulation tool, namely WiFiSim, aimed at the generic study of IEEE 802.11-based WLANs in a disciplined way. The interest of this tool, which has been developed by the authors, lies in its ability to simulate realistic and customizable WLAN environments, high interactivity and user-friendly interface, and intuitive and easy-to-interpret 3D graphic results. These help students in wireless network modeling and deployment with improved reach and realism. In order to validate this basis, we tested WiFiSim under different simulation conditions. As a result, the teaching experience has demonstrated the effectiveness of the followed methodology and significantly reduced the gap between theory and practice. (C) 2013 Elsevier Ltd.
