Unencapsulated Mobile Multicast Routing for Next Generation Video Networks [chapter]

Thomas C. Schmidt, Matthias Wählisch, Hans L. Cycon, Mark Palkow, Henrik Regensburg
2006 Lecture Notes in Computer Science  
It is built as a simple, ready-to-use scheme for distributed presenting, recording and streaming multimedia content over next generation unicast or multicast networks.  ...  We propose extensions to multicast routing for transforming (morphing) previous delivery trees into optimal trees rooted at a relocated source.  ...  The Mobile Multicast Source Problem Problem Statement Any next generation Internet support for multicast source mobility management is required to operate transparently w.r.t. the socket layer.  ...

Scalable Mobile Multimedia Group Conferencing Based on SIP Initiated SSM

Thomas Schmidt, Matthias Wahlisch, Hans Cycon, Mark Palkow
2007 Fourth European Conference on Universal Multiservice Networks (ECUMN'07)  
Multimedia group communication emerges to focal interest at mobile devices, enriching voice or video conferencing and complex collaborative environments.  ...  The traditional Internet approach of Any Source Multicast (ASM) routing, though, remains hesitant to spread beyond limited, controlled environments.  ...  We introduced, discussed and analyzed signalling extensions of SIP and routing methods to adapt SSM to source mobility.  ...

A Light-Weight Implementation Scheme of the Tree Morphing Protocol for Mobile Multicast Sources

Olaf Christ, Thomas C. Schmidt, Matthias Wahlisch
2007 33rd EUROMICRO Conference on Software Engineering and Advanced Applications (EUROMICRO 2007)  
This distributed routing algorithm allows for a continuous adaptation of multicast shortest path trees to source mobility.  ...  However, mobility support for Source Specific Multicast is still known to be a major open problem.  ...  In this paper we address the issue of mobile multimedia group communication, taking the perspective of Source Specific Multicast routing on the network layer.  ...

Extending SSM to MIPv6 – problems, solutions and improvements

Thomas C. Schmidt, Matthias Wählisch
2005 Computational Methods in Science and Technology  
As the common approach of Any Source Multicast distribution is burdened with intricate routing procedures, the spread of multicast-enabled network infrastructure remains hesitant.  ...  However, SSM is designed for theá priori known and changeless addresses of multicast sources and thus withstands any easy extension to mobility.  ...  IP multicasting may soon turn out to be the only feasible technique to be considered. The next generation Internet will need to provide seamless support of mobility.  ...

AuthoCast-a mobility-compliant protocol framework for multicast sender authentication

Thomas C. Schmidt, Matthias Wählisch, Olaf Christ, Gabriel Hege
2008 Security and Communication Networks  
Voice and video (group) conferencing, as well as large scale content distribution, e.g., IPTV or massive mutliplayer games (MMORPGs) are considered the key applications for the next generation ubiquitous  ...  This lightweight scheme smoothly extends the unicast enhanced route optimization for mobile IPv6 and adds only little overhead to multicast packets and protocol operations.  ...  We thank the referees for their thorough advices which helped significantly in improving this article.  ...

Fast adaptive routing supporting mobile senders in Source Specific Multicast

Thomas C. Schmidt, Matthias Wählisch, Maik Wodarz
2009 Telecommunications Systems  
IP multicast deployment recently progresses, but group services often remain restricted to limited domains and fail to comply with route-optimizing mobility management of the next generation Internet.  ...  In this paper, we propose the Enhanced Tree Morphing (ETM) protocol for extending SSM routing to mobile multicast sources.  ...  Xylomenos & Polyzos [8] introduced home subscription and remote subscription for mobile nodes as the two basic mechanisms that remain compliant to generic multicast routing.  ...

Adaptive shared tree multicast in mobile wireless networks

Ching-Chuan Chiang, M. Gerla, L. Zhang
IEEE GLOBECOM 1998 (Cat. NO. 98CH36250)  
Shared Tree multicast is a well established concept used in several multicast protocols for wireline networks (eg. Core Base Tree, PIM sparse mode etc).  ...  In this paper, we extend the Shared Tree concept to wireless, mobile, multihop networks for applications ranging from ad hoc networking to disaster recovery and battlefield.  ...  To begin, the shortest tree from each source to all destinations generally comes for free since it is embedded in the routing tables generated by the most common routing algorithms such as Distance Vector  ...
