Uplink Packet Scheduling Schemes for Video Traffic in Wireless Communication Systems

摘要

We propose three different uplink packet scheduling algorithms for OFDMA-based wireless communication system through video traffic analysis and analyze their performances. The video traffic is assumed to be generated its packets according to the Pareto distribution parameters. The packet scheduler at the base station is able to do the priority-based resource allocation based on the information collected from the mobile stations. Defining the uplink scheduling classes according to the presence and the amount of the collected information, we propose, based on that, three kinds of uplink packet scheduling algorithm: BUS-DAP, PUS-DAP and AUS-PLF. Simulation results show the proposed AUS-PLF algorithm offers better channel capacity than the others.
