Investigative Analysis of Improved QoS Support for WIMAX Networks”, in Proceedings of 8th International Conference on ICT Application

Abstract

Quality of Service (QoS) is considered as the backbone of any Broadband media access network of which Worldwide Interoperability for Microwave Access (WiMAX) is not an exception. Consequently, this area has gathered a lot of interest from academic researchers and industrialists with the goal of coming up with improved QoS service to support different traffics in WiMAX network. This research work is an investigation of the various state of the art QoS schemes that have been proffered as solutions to this challenge. It presents an investigative analysis of three approaches - the hierarchical scheduling approach for improving QoS Service in WiMAX which divides the scheduling scheme into three different tiers, cross-layer optimization approach for improving QoS in WiMAX and on demand bandwidth allocation approach for improving QoS in WiMAX. The performance evaluation of each of the approaches are investigated using the same metrics and then presented for making trade-offs decisions.
