15:15 – 16:45 Session 2
Fragmentation and federation: redefining the role of a network in beyond 3G telecommunications
Dr. Antonio Cuevas, University of Stuttgart

The traditional public telecommunications networks (radio or TV broadcasting, fixed and mobile telephony) are a monolithic business where the operator controls almost all the aspects, from the network to the services delivered over it. The Internet irrupted bringing a complete different share in the business. In the Internet, the operator just transports the information (it is a bit pipe) and the network is widely opened to any parties to deliver their services. There is an immense panoply of services offered with great user acceptance. In this rich service ecosystem, the application providers are specialized but the cooperation between them and with the network operator is not yet very well developed. Fomenting this cooperation will benefit the users who, for instance, would have unique logging and billing points (like paypal) and the network operators would gain a more prominent role than just being a bit pipe. Moreover, since more and more devices have processing and telecommunication capabilities, the universe of cooperating applications, devices, networks, service providers is enlarged. Advanced federation techniques are key to make the most out of the future telecommunications.

Day 2 - Tuesday, 29 July

09:00 – 10:30 Session 4
Context-Awareness and Service Discovery in Pervasive Computing Environments
Nikos Kalatzis (MSc), National Technical University of Athens

10:45 – 12:15 Session 5
Personalisation, Learning, Security and Privacy in Pervasive Systems
Sarah McBurney & Eliza Papadopoulou (BSc), Heriot-Watt University

As the user navigates through their pervasive environment they have access to an expanding array of surrounding services and resources vying for his/her attention and requiring some level of management and configuration. For this reason personalisation has become an important component under the pervasive umbrella, managing and configuring environments to meet each individual user’s needs. The success of personalisation provided is dependent on the quality of user information (i.e. preferences) held. Requiring the user to explicitly manage their preferences may discourage system use leading to a barren preference set and mediocre personalisation. A more beneficial approach provides implicit preference management including monitoring and learning mechanisms. With such large stores of potentially sensitive user information available, security and privacy is vital in pervasive environments. With regards to security, encryption algorithms are necessary to ensure communication integrity, authenticity and confidentiality. With regards to privacy, mechanisms must exist to ensure access control to user data as well as user anonymity. The true identity of the user must be kept private and unknown to other users. One solution is the use of virtual identities. It is true that the aims of security and privacy are in direct contrast with those of personalization and learning. A balance must be found to provide optimum benefit from both sides.

13:45 – 16:15 Session 6
Virtual Identities - Preserving Privacy in the Network layer
Alfredo Matos, Prof Rui Aguiar, University of Aveiro

16:00 – 17:00 Session 7
Identity Management In Internet and Telecommunications Systems
Marcin Dabrowski, Akademia Gorniczo-Hutnicza

Interoperable Identity Management systems are prerequisite for novel user-centric services, which strongly rely on user identity attributes and security services. Future Identity Management systems have to provide a framework which will enable dynamic and automatic exchange of user identity attributes between services from different key-business areas, e.g. Internet, healthcare, e-government, e-banking, entertainment, etc. The framework should allow federating different user identities so that any of them would be sufficient to bootstrap trust relation between the user and any service. The presentation will provide an introduction to Identity Management, it will shortly present current Identity Management standards and specifications and finally, it will show what current Identity Management systems lack in and it will present the general architecture of future Identity Management systems.

Day 3 - Wednesday, 30 July

09:00 – 10:30 Session 9
Wireless Mesh Networks for the Future Internet
Prof Dr Andreas J. Kassler, Karlstad University

Wireless multi-hop networks such as Wireless Mesh Networks (WMN) offer an attractive alternative for providing rapid and cheap broadband wireless internet connectivity, especially for localized and community aware communication. They present a paradigm shift from current internet architecture towards a totally decentralized, self-managed, scalable and adaptive wireless access network eliminating the need for cables. The application potential of WMNs is enormous including scenarios like emergency communications, home networks, community and neighborhood networking and services, or enterprise networks. Key challenges in WMN research are the development of multi-channel, multi-radio MAC and routing protocols enabling a decentralized adaptive radio resource management. Delivering carrier-grade quality requires a proper planning and dimensioning of WMNs, resilient routing helps to increase the survivability of the network in case of failures. This tutorial will give an overview on state of the art in WMN research, identifying key research challenges and solution proposals for current hot topics. Trends in standardization are illustrated together with ongoing projects and testbed deployments. A general classification of WMNs will be introduced and put into relation with IEEE802.16 Mesh mode and 802.11s.

Optimising Vehicular Communications from a MANEMO (MANET+NEMO) Perspective
Prof Dr. Carlos J. Bernardos, Prof Ignacio Soto, Universidad Carlos III de Madrid

This talk presents the research conducted within Daidalos project related to enabling and optimising vehicular communications. This covers aspects of basic Network Mobility (NEMO), as well as specific issues that have been tackled, such as Route Optimisation and the secure integration of NEMO and Vehicular Ad-hoc NETworks (VANETs) -- what is known as the MANEMO concept. It is also described and analysed how the MANEMO approach fits within the vehicular communications scenario, by identifying how the integration of Network Mobility and ad-hoc networks could improve the performance of vehicular communications when compared to classical approaches. As practical examples of mechanisms developed within Daidalos, the basic operation of a both a Route Optimisation solution -- MIRON: Mobile IPv6 Route Optimisation for NEMO -- and a MANEMO solution -- VARON: Vehicular Ad-hoc Route Optimisation for NEMO -- are explained. Finally, some conclusions about current and future research lines are provided.
