Performance Evaluation of Wimax Quality of Service Scheduling Classes

Abstract

Worldwide Interoperability for Microwave Access (Wimax) is an innovative and cost effective technology that allows fast and easy delivery of broadband wireless access for fixed as well as mobile users. The most famous Wimax quality of service classes are: Unsolicited Grant Services (UGS), Extended Real-Time Polling Services (ERTPS) and Best Effort (BE).This work is comparative study to evaluate these classes in term of packet loss, end to end delay, jitter, throughput and voice traffic sends. The evaluation is carried out using an OPNET simulation. Results show that UGS class out performs ERTPS while the BE class has the least quality compared to other classes.
