Abstract: For supporting resource-limited mobile clients, such as the PDA, with the QoS-guaranteed real-time SMIL multimedia presentation over the wireless ATM network, we propose an adaptiveprefetching protocol for VBR-encoded streaming objects between the mobile client and the media server to minimize the size of extra buffer under fluctuated ATM ABR bandwidth and transmission delay. Simulation results exhibit excellent performances of this protocol for VBR video clips with different degrees of bit rate burstiness. Further, the scenario to reduce the protocol overhead, i.e., the number of transmitted control messages, is described. We also investigate the tradeoff between the size of extra buffer and the frequency of control messages.
