Mobile Multimedia Group Conferencing - Video Based System and its Future Use in Mobility Aware SSM Infrastructure

In this paper we report on a multimedia communication software with a distributed architecture and its applications. It is a simple, ready-to-use scheme for distributed presenting, recording and streaming multimedia content over unicast or multicast networks. We will also report on its future applications within mobile networks. Additionally we present a straightforward extension to multicast routing for transforming (morphing) source specific delivery trees into optimal trees rooted at a relocated source. This extension scheme only requires basic signaling mechanisms, explicit joins and prunes, which are present in current multicast routing protocols such as PIM-SM
