Evaluation and Comparison among Scheduling Algorithms in WiMAX

Ramanpreet Kaur, Amardeep Kaur

Abstract


WiMAX is one of the most prevailing networks in the world. There are many concerning issues regarding WiMAX and scheduling of resources is one of them. In this paper, we have evaluated and compared various WiMAX scheduling algorithms such as CAC, MWRR, Modified Priority scheduling algorithm and Proportional Fair scheduling algorithm. We have implemented and simulated these scheduling algorithms using OPNET Modeler. From the results it is concluded that Modified Priority scheduling algorithm is having maximum delay in the network. MWRR and Modified Priority scheduling algorithm are having maximum and minimum load respectively. CAC and Modified Priority scheduling algorithm have high throughput.

Keywords: WiMAX, OPNET Modeler, scheduling algorithms, QoS.
