Towards Seamless Source Mobility in SSM - Design and Evaluation of the Tree Morphing Protocol
International Journal of Internet Protocol Technology (IJIPT), 3(4):205--215

Marker: TI-I

Zusammenfassung: Multimedia networking in the near future is expected to be dominated by group applications such as IPTV, MMORPGs, and video conferencing. Hand in hand with new service offers, the deployment of multicast at the network layer started to disseminate. Currently infotainment is gradually expanding into the mobile world, but a standard design of mobile multicast is still awaited. In this paper we present a design and discuss an extensive evaluation of the Tree Morphing Protocol that performs an adaptive tree management to support seamless handovers for mobile SSM sources. Based on a full protocol implementation on a network simulator platform, we extensively explore the protocol performance. By employing artificial networks to cover fundamental topological constellations, as well as real-world network topologies, we analyze the handover behavior conceptually and in realistic scenarios. Strengths and weaknesses of the routing scheme are identified, leading to a discussion on future improvements.

AuthoCast --- a mobility-compliant protocol framework for multicast sender authentication
Security and Communication Networks, 1(6):495 -- 509

Marker: TI-I

Zusammenfassung: Mobility is considered a key technology of the next generation Internet and has been standardized within the IETF. Rapidly emerging multimedia group applications such as IPTV, MMORPGs and video conferencing increase the demand for mobile group communication, but a standard design of mobile multicast is still awaited. The open problem poses significant operational and security challenges to the Internet infrastructure. This paper introduces a protocol framework for authenticating multicast sources and securing their mobility handovers. Its contribution is twofold: At first, the current mobile multicast problem and solution spaces are summarized from the security perspective. At second, a solution to the mobile source authentication problem is presented that complies to IPv6 mobility signaling standards. Using an autonomously verifiable one-way authentication based on cryptographically generated addresses, a common design is derived to jointly comply with the mobile any source and source specific multicast protocols that are currently proposed. This light-weight scheme smoothly extends the unicast enhanced route optimization for mobile IPv6 and adds only little overhead to multicast packets and protocol operations.

Video-based eLearning in Groups --- Combining SIP and Multicast in a Mobile Learning Internet Infrastructure
International Journal of Mobile Learning and Organisation (IJMLO), 2(4):329--345

Marker: TI-I

Zusammenfassung: Rich multimedia communication in groups is the instrument of choice in various e-learning situations and is best achieved by videoconferencing, supplemented by collaborative tools. In this paper, we report on various distributed synchronous and asynchronous video-based teaching and learning scenarios using stationary and mobile technologies over IP. They are realised by a multimedia communication system including a VideoConferencing over IP (VCoIP) software with hybrid architecture derived from a SIP-initiated P2P model. The system is based on a fast, highly efficient H.264/AVC video codec implementation. We investigate new concepts for nomadic IPv6 user and session mobility, focussing on real-time group communication.
