Abstract: |
Scheduling plays an important role in providing quality of service (QoS) support to wideband multimedia communication network, especially in multicast communication. Thus, it is essential to propose efficient and high-speed multicast scheduling policies for the multimedia network, which could perform well in the inherent performance properties such as latency and throughput. However, most researches only addressed one aspect of the QoS support, such as latency, throughput and priority, rarely concentrated on various properties. This paper proposes a new multicast scheduling algorithm, called PWBA, which balances the trade-off between throughput and latency and takes the priority into consideration, for the purpose of providing better QoS support to the multimedia network. Its performance is evaluated via simulations.
