Mobility assisted opportunistic scheduling for downlink transmissions in cellular data networks

The paper presents an online opportunistic scheduling algorithm for downlink transmission in a time-slotted shared wireless network that combines channel fluctuation and user mobility information in the decision rule. The algorithm is a general scheduling scheme and adapts well with any utility function for elastic traffic. For finite workload service demands, the scheme uses less completion time than the max-rate scheduling scheme. Under moderate load conditions, it gives time savings of up to 10%. For infinite backlog service demands, the proposed algorithm performs better than the proportional fair algorithm. Simulation results illustrate the usefulness of the proposed scheme for elastic traffic and moderate load conditions.
