Performance Evaluation of Wireless IEEE 802.11b used for E-Learning Classroom Network

This paper presents an evaluation study of an IEEE 802.11b wireless LAN (WLAN) applied in E-learning classroom. The simulation is conducted using OPNET IT Guru 9.1. Also, this paper presents a simulation study to estimate the appropriate number of E-learning clients that can be supported in the WLAN as well as the user-perceived Web response time as a function of network load. Our simulation results show that an IEEE 802.11b WLAN can support up to 50 clients with modest E- learning and Web browsing activities.
