Abstract
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 simultane- ously 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 band- width 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 pub- lished work.

Abstract
In an environment where IEEE 802.16 access networks are used as a backbone for a heterogeneous wireless access network, the question of Quality of Service brings along a questioning on several other aspects: scalability, guarantees, scheduling among others. We give in this paper a general solution answering those questions. This solution is based on an aggregated bandwidth management in the backbone. This aggregation along with specific bandwidth request and scheduling policies are herein specified and discussed.

Abstract
This paper presents the Expected Link Performance (ELP) metric for finding high throughput, low delay paths in 802.11 mesh networks. ELP combines three different mechanisms to accurately determine the expected link performance. Link quality information is combined with cross-layered link interference estimation to select optimal paths. Simulation results show that ELP significantly outperforms both hop count as well as the popular ETX metric. ELP has up to 12% higher throughput and about 40% smaller delay than ETX.
