چکیده

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.

Priority Based Uplink Scheduler for Ieee 802.16 Networks

IEEE 802.16, the standard for fixed, portable and mobile Broadband Wireless Access (BWA) systems, is promising to support different classes of traffic with Quality of Service (QoS). The Medium Access Control (MAC) protocol defines a wide variety of mechanisms for bandwidth allocation and QoS provision. However, the details of how to schedule traffic are left unspecified. In this paper, we propo...

Resource Management and QoS Provisioning for Duplex Services in IEEE 802.16

Duplex services are multimedia services that requires good connectivity in both uplink and downlink such as VoIP, video conferencing and interactive gaming. A weak connection in either directionmay cause degradation of performances and dissatisfaction of user experience.Most researchers do not consider this issue and treat resource allocations in uplink and downlink independently. For this reas...

Dynamic Bandwidth Allocation for QoS in IEEE 802.16 Broadband Wireless Networks

IEEE 802.16 broadband wireless access (BWA) technology is suitable for providing multimedia applications without accessing the wired networks directly. Although IEEE 802.16 standard well defines the quality of service (QoS) framework, it makes no specific recommendation with regard to the bandwidth allocation. In this paper, we propose an algorithm for allocating bandwidth in response to dynami...
