Quality of Service Performance Evaluation of WiMAX (IEEE 802.16) using OPNET

Institution

Northern Kentucky University

Abstract

Mobile WiMAX was officially drafted by the International Technological University (ITU) in late 2007. Much advancement has been made to improve the quality and performance of this OFDM-based technology. Officially, the IEEE 802.16e revisions promote standards for broadband wireless access systems and currently focus on performance through the PHY and MAC layers. This work evaluates the design and layout of a WiMAX deployment in terms of the physical layer's QoS (Quality of Service) variables; such as digital modulation and coding and forward error-correcting protocols. Among altering the framework and structure of the network, this work further delves into the performance evaluation through enhancing the uplink (UL) and downlink (DL) states to use OFDM oriented frequency-selective modulation schemes in an OPNET based project.
