An Uplink Bandwidth Management Framework for IEEE 802.16 with QoS Guarantees

摘要

This paper presents a novel uplink bandwidth management framework for IEEE 802.16 WiMAX. This framework is destined to be used in a scenario where a large number of connections are simultaneously active, as may be the case when WiMAX is used as a backhaul for WiFi hotspots. In such a scenario we propose a simple and efficient scheduling discipline for the WiMAX uplink traffic. We also propose an admission control algorithm and a modification of the complex bandwidth request mechanisms. The framework we propose in this paper was analyzed: simulation results show a significant performance improvement in terms of overall throughput and delay when compared to recently published work.
