Abstract
In this paper, we propose an adaptive urgency and efficiency based packet scheduling (A-UEPS) algorithm that is to designed to maximize throughput of non-real-time (NRT) traffics as long as QoS requirements of real-time (RT) traffics such as the packet delay and the loss rate requirements are satisfied. In addition, the A-UEPS algorithm provides trade-off between performance objectives of RT and NRT traffics adaptively by adjusting scheduling precedence of packets of RT and NRT traffics in accordance with the time-varying traffic situations such as the offered traffic load and traffic mix. Simulation study shows that A-UEPS algorithm results in efficient and adaptive scheduling performance under various traffic situations.
