Enhanced QoS support in OFDMA-Based WiMAX Systems
Keywords:
WiMAX, QoS, OFDMA, MBMSAbstract
Worldwide Interoperability of Microwave Access (WiMAX) network offer promising opportunities for unwiring the last mile connectivity to the internet with its comprehensive support of Quality of Service(QoS). Everything has a disadvantage or a problem to be fixed, WiMAX also has a problem that is to provide QoS when providing data, audio and video services. Actually it‟s not a problem though as it supports orthogonal frequency division multiple access (OFDMA) technology. However the combination of several technologies like OFDM, OFDMA assures the QoS of WiMAX. One of the main features in a WiMAX MAC layer is that it can provide differentiated services among different traffic categories with individual QoS requirements. In this research paper the research team first give an overview of the key aspects of WiMAX and describe Multimedia broadcast multicast service (MBMS) architecture and then propose a broadcast architecture for WiMAX that is based on MBMS to increase the QoS of Multimedia Streaming in WiMAX.
