Solutions for IPv6-based mobility in the EU project MobyDick

Proceedings of the WTC 2002, 18th World Telecommunications Congress, Paris, France, 22 -27 September, 2002.Mobile Internet technology is moving towards a packet-based or, more precisely, IPv6-based network. Current solutions on Mobile IPv6 and other related QoS and AAA matters do not offer the security and quality users have come to take for granted. The EU IST project Moby Dick has taken on the challenge of providing a solution that integrates QoS, mobility and AAA in a heterogeneous access environment. This paper focuses on the mobility part of the project, describes and justifies the handover approach taken, shows how QoS-aware and secure handover is achieved, and introduces the project's paging concept. It shows that a transition to a fully integrated IP-RAN and IP-Backbone has become a distinct option for the future.Publicad

Supporting Trust and Privacy with an Identity-Enabled Architecture

Cost reduction and a vastly increased potential to create new services, such as via the proliferation of the Cloud, have led to many more players and “end points”. With many of them being new entrants, possibly short-lived, the question of how to handle trust and privacy in this new context arises. In this paper, we specifically look at the underlying infrastructure that connects end-points served by these players, which is an essential part of the overall architecture to enable trust and privacy. We present an enhanced architecture that allows real people, objects and services to reliably interact via an infrastructure providing assured levels of trust

Pervasive Services for Next Generation Heterogeneous Networks

The overall goal of the European collaborative project Daidalos is to design, develop and validate a framework for next generation mobility-enabled networks. Envisioned scenarios include heterogeneous access networks, while requiring ubiquitous, services of adequate quality, broadcast integration, as well as the ability to support privacy and anonymity while making life easier for the end-user. This paper introduces the five key concepts of the EU IST project Daidalos and how these address such diverse challenges, and sketches achievements so far

FleetNet: Bringing Car-to-Car Communication into the Real World

Car-to-car communication by means of wireless technology shows a strong potential to enhance both safety and comfort of road users. The necessity to reach cars beyond the transmission range of the own radio creates the challenge to find algorithms to efficiently forward packets. In these so-called vehicular ad hoc networks, position information has been identified as a crucial component that alleviates some of the limitations of existing topology-based protocols. Thus, we see the use of positional information at the core of a car-to-car communication system that provides advanced applications for active safety, distributed floating car data, as well as user communication and information. A major thrust to leverage a car-to-car communication platform was provided by the FleetNet project, partly funded by the German Ministry of Education and Research BMB+F and led by DaimlerChrysler AG. Based on ad hoc networking principles and the availability of position information, the project developed suitable communication concepts. In addition to simulation studies, a prototype communication and application system was implemented and deployed, embedding safety and convenience applications. With car-based real world field trials successfully conducted, first results and experiences look promising
