Abstract:
Recent mobile technologies allow users to interact with each other through voice and video by using smart-phones or tablets. The applications available on the Internet are mostly using a similar protocol which is best-effort data network by service provider. Best effort service does not guarantee data to be delivered within the allocated time. Real-time applications compete equally for network resources in best effort, hence real-time application perform poorly using best effort services. In this paper, two classical packet schedulers and two channel-aware schedulers for Orthogonal Frequency-Division Multiple Access (OFDMA) are studied. The schedulers are simulated using real-time packets with a various channel condition of user equipment (UE) in NS3 simulator to test the performance of each scheduler. The Channel-Quality of Service (QoS) Aware scheduler outperforms all other schedulers for real-time traffic.
