Performance evaluation of MPEG-4 video transmission with the Adaptive Smooth Multicast Protocol (ASMP)

We present in this work the performance evaluation of MPEG-4 video transmission with our proposed single rate multicast protocol named Adaptive Smooth Multicast Protocol (ASMP). ASMP key attributes are: a) adaptive scalability to large sets of receivers, b) TCP-friendly behavior, c) high bandwidth utilization, and finally d) smooth transmission rates which are suitable for multimedia applications. We evaluate the performance of ASMP under an integrated simulation environment which extends ns-2 and Evalvid-RA to the multicast domain with the use of the RTP/RTCP protocols. Simulations conducted under this environment combine the measurements of network-centric along with video quality metrics. This “joint” evaluation process provides a better understanding of the benefits and limitations of any proposed protocol for multimedia data transmission.
