A performance comparison for QoS with different WiMAX environment for video application

Abstract

Future generation networks will be characterized by variable and high data rates, quality of services, seamless mobility both within a network and between networks of different technologies and service providers. An important aspect of components in a global next generation network is standardization to allow vendor independence and interoperability. A technology developed to fulfill these characteristics, standardized by IEEE, is 802.16, also referred to as WiMAX. This architecture aims to apply high data rates, quality of services, long range and low deployment costs to a wireless access technology on a metropolitan scale. This paper focuses on WiMAX since this wireless technology allows broadband communications. In particular, we provide here a preliminary study on MAC layer performance as well as a sensitivity study to its parameters. In this paper I have implemented the performance comparison with different WiMAX environment for video application under UGS (Voice over IP (VoIP) without silence suppression) with respect to Throughput, Load and Delay. A simulation approach has been adopted, based on a simulation tool known as OPNET Modeler 14.5.
