A performance analysis of packet scheduling algorithms between homogeneous algorithm and hybrid algorithm in point to multipoint WiMAX networks

WiMAX (Worldwide Interoperability for Microwave Access) is a wireless technology that provides long distance broadband connectivity. It has high speed access, wide coverage areas, and provides various types of services. Applying WiMAX has challenging problem when it has to provide quality assurance of service (QoS) for different types of services with diverse QoS needs. To meet the QoS requirements, a scheduling algorithm is needed. Scheduling algorithm is to regulate the transmission of data packets, such as regulating the sharing of resources (bandwidth) for each user. This research implemented a WiMAX network simulation scheduling algorithm with homogeneous and hybrid algorithm methods. Representatives on the homogeneous algorithms method used Weighted Fair Queuing scheduling algorithm (WFQ) and Deficit Round Robin (DRR), whereas the hybrid algorithm method used a merge between DRR and WFQ scheduling algorithm. Testing the performance of the scheduling algorithm was performed by comparing the QoS class into 5 types, namely WiMAX UGS, RTPS, nRTPS, eRTPS and Best Effort. The parameters used to test the performance of a WiMAX network are throughput, packet loss, delay and jitter.
