Performance Evaluation of Quality of Service Algorithms in Wimax Networks

Abstract

The IEEE 802.16 standard defines the specifications of the Worldwide Interoperability for Microwave Access (WIMAX) technology as a Broadband Wireless Access network. This type of networks supports multiservice traffic (voice and video) and guarantees the Quality of Service (QoS). The standard specifies four scheduling service algorithms to support QoS This thesis provides an analytical study for voice interactive and video streaming performance in WIMAX networks, Parameters that indicate the Quality of Service such as delay, jitter, reliability and WIMAX throughput are analyzed over two scheduling services algorithms namely, UGS,RTPS compare with a novel scheduling service algorithm called ERTPS. The analysis includes check the compatibility for each scheduling service algorithm which include voice and video streaming and check out which scheduling services are better for voice and video interactive. OPNET network simulator is used to evaluate the performance of the three scheduling service algorithms.
