Abstract

WiMAX, the acronym for Worldwide Interoperability for Microwave Access is a set of technical standards based on IEEE 802.16 standard. It provides wireless connection of companies or individuals over long distances at high speed, it's an adequate response to some rural or inaccessible areas. Unlike DSL (Digital Subscriber Line) or other wired technology, WiMAX uses radio waves and can provide point-to-multipoint (PMP) and Mesh modes. In parallel, Voice over IP (VoIP) technology is the biggest revolution in communication technology. It replaces the traditional telephone service and offers free long distance calls. Video stream traffic is characterized by the ability to transmit real-time and interactively visual and auditory information. VoIP and Video traffic are highly delay intolerant and need a high priority transmission. In this paper, we analyze the performances of the most common VoIP codec, namely G.711, and video streaming H.263 format using BE, rtPS, UGS, ertPS and nrtPS service classes and NOAH routing protocol. NS-2 simulator is used to analyze the QoS parameters. Our objective is to analyze different WiMAX service classes with respect to the QoS parameters such as, average jitter, throughput and average delay while increasing mobile nodes.
