Abstract :
We propose a routing scheme to support synchronization of multimedia units (MMU) for mobile clients and wireless multimedia systems that makes use of base stations as quasi-receivers to control the MMU synchronization. Our scheme allow mobile hosts to receive multimedia units without delivering interruption while mobile hosts are moving from one cell to another cell. The proposed solution not only enhance the performance of MoSync, a synchronization mechanism for wireless multimedia systems, which we have developed earlier but also cope with network-jitter, end-system jitter clock drift, and changing network conditions during soft-handoff. Thus, our scheme is suitable both for synchronizing inter- and intra-streams during playback video and also for resynchronize streams in a wireless network. We present our soft hand-of management scheme, and provide their proof and correctness.
