Performance evaluation of packet scheduling and synchronization algorithms for wireless multimedia systems

While multimedia synchronization in wired environments has been well studied in the past, very little studies have been done for wireless networks. In this paper, we study the multimedia synchronization problem for wireless and mobile networks. We present a performance evaluation of MoSych algorithm and investigate the effect of four media packet scheduling algorithms on MoSych (first in first out, highest priority first, weighted fair Queuing and round robin). We also report the results we have obtained to analyze the effect of these four packet scheduling algorithms in terms of mobile client's buffer usage and delay between multiple data streams.
