PWBA: A Novel Multicast Scheduling Algorithm for Wideband Multimedia Satellite Communications

Abstract:

Satellite multicast service expands the application of wideband multimedia satellite. Scheduling plays an important role to guarantee Quality of Service (QoS) for wideband multimedia multicast services. In this paper, considering various properties of QoS requirements of latency, throughput and priority, a PWBA multicast scheduling algorithm is proposed to balance trade-off between throughput and latency in order to providing better multimedia services in satellite networks. Comparing with the WBA and PGMF multicast scheduling policies, the proposed PWBA has better performances in both latency and throughput.
