Synchronized End-to-End Multicast in Real-Time Packet Cellular Networks

In this paper 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). 1 INTRODUCTION In packet cellular networks, to support real-time applications such as multimedia, command and control systems, etc., the network should provide seamless Quality of Service (QoS) to mobile hosts as they roam about. In this paper, the problem of real-time multicast in packet cellular networks is studied, the solution of which may be applied to military or civilian information dissem..
