Abstract

Almost all deployed implementations of the IEEE802.16 standard (also known as WiMAX) employ the Point to Multipoint (PMP) topology. With such a topology Quality of Service (QoS) can be easily achieved, but the coverage area is limited. The other architectural topology is the Mesh Mode which is able to provide a larger coverage area, but cannot support the QoS required. This paper addresses the issue of supporting QoS for WiMAX when used in a Mesh Mode configuration. Doing so will motivate WiMAX vendors to support the Mesh Mode configuration for their WiMAX systems more cost-effectively. Our proposed approach makes use of an efficient Bandwidth Manager, a Packet Scheduler and an Admission Control mechanism. The Bandwidth Manager utilizes the 'Deficit Round Robin' algorithm, and the Packet Scheduler uses a 'Self-Clocked Fair Queuing' scheduling algorithm. The performance results obtained with the proposed scheme demonstrate that QoS support is achievable in this mode.
