A QoS Oriented Analysis of ertPS, rtPS and nrtPS flows in WiMAX

In the new era of communication, WiMAX (IEEE 802.16) is the most emerging technology that enables ubiquitous delivery of broadband wireless access for fixed and mobile users. It is a more innovative and commercially viable alternative to cable modems and DSL technologies as it is cost effective, easy to implement, high performance and high resource utilization technology. Quality of Service (QoS) is an important consideration for supporting variety of applications that utilize the network resources. This paper focuses on quality of service oriented analysis in WiMAX networks with CBR traffic. Different types of QoS parameters like packet loss, average throughput, average jitter and average end to end delay are investigated with CBR traffic and effect of mobility are evaluated using QualNet 6.1 Wireless network Simulator for rtPS, nrtPS and ertPS flows. The goal is to compare the Quality of Service parameters of the three service flows with respect to mobility so that different types of service flows can be used in optimal way for real life scenarios.
