Synchronized end-to-end multicast in real-time packet cellular networks

We present and evaluate protocols (SMP and SMP-MH) for synchronized end-to-end multicast in real-time packet cellular networks. Our protocols extend current delay jitter control mechanisms to achieve synchronized real-time packet delivery to mobile hosts in multiple cells. We show that for a multicast session using SMP and SMP-MH: (1) the end-to-end delay bounds of each packet to the subscribing mobile hosts are identical, with small and bounded jitters, and (2) a mobile host can experience smooth, brief and lossless handoffs, and thus receive seamless quality of service (QoS)
