摘要：The ever-expanding and explosive growth of the Internet over the last decade has led to an increasing demand for high-speed, ubiqu itous In ternet access. Broad band Wireless technologies are increasingly gain ing p opularity by the successful glo bal deployment of the Wireless Personal Area Networks (Bluetooth- IEEE 802.1 5.1), Wireless Local Area Networks (WiFi- IEEE 802.11b), and Wireless Metropolitan Area Networks (WiMAX-IEEE 802.16a). In this paper we have used the QualNet Simulator to analyze the performance of IEEE 802.11b, 802.15.1, and 802.16a Standards by varying mobility of the nodes. The performance metrics measured in this study includes end-to-end delay, packet-loss ratio, and throughput. The results show how mobility affects the performance of IEEE 802.11b, 802.15.1 and 802.16a
