Context-awareness and personalisation are important concepts that are essential cornerstones in future systems providing pervasive services. These two concepts are closely interrelated and dependent on each other for fully functional context-aware personalised services. Daidalos is a European research project in the area of 3G and beyond, which aims to combine heterogeneous networks in a transparent and seamless way, and develop a pervasive environment for applications and end-users on top of this. The first phase of implementation has produced a basic system that is currently being developed further. This paper outlines the basic pervasive service platform architecture and describes the context-awareness and personalisation features that are being implemented in Daidalos.

Summary form only given. In pervasive computing the involved agents and services must organize themselves dynamically both in cooperative and non-cooperative environments in order to enable sharing of distributed resources and knowledge discovery. Provisioning of trusted services appears to be an important factor to enable the success of this new computing paradigm. Reputation-based trust management models are becoming a focus of the research community as a viable solution. On the one hand, the trust models must satisfy constraints imposed by the environment, such as scalability, on the other hand, they must comply with the unique properties of trust as a social and economic phenomenon. In this paper we classify and compare approaches that have been proposed to fulfil this task. The identified classes are: social networks, probabilistic estimation techniques and game-theoretic reputation systems. Social networks and probabilistic estimation techniques operate on so called probabilistic behavior, while game-theoretic models are suitable for rational behavior. Probabilistic techniques normally imply smaller implementation overheads than social networks and enable a more intuitive transition of reputation to trust, while social networks are believed to be able to better detect misbehavior in a broader range of settings. Game-theoretic models, as appropriate for rational economic agents maximizing their utilities, can under specific circumstances enforce trustworthy behavior.

In this paper we focus on the role of location in cooperative settings. We first sketch how information on users and devices location is used to support collaboration and discuss the implications for the design of location services for collaboration. We then present how Ubicollab, a collaborative platform that we are developing, can be extended to include location support.

Multiprocessors are coming into wide-spread use in many application areas, yet there are a number of challenges to achieving a good tradeoff between complexity and performance. For example, while implementing memory coherence and consistency is essential for correctness, efficient implementation of critical sections and synchronization points is desirable for performance. The multi-checkpointing mechanisms of Kilo-Instruction Processors can be leveraged to achieve good complexity-effective multiprocessor designs. We describe how to implement a Kilo-Instruction Multiprocessor that transparently, i.e. without any software support, uses transaction-based memory updates. Our model not only simplifies memory coherence and consistency hardware, but at the same time, it provides the potential for implementing high performance speculative mechanisms for commonly occurring synchronization constructs.

The primary objective of pervasive computing environments (PCE) is the creation of an environment saturated with seamlessly integrated devices with computing and communication capabilities. It seeks to provide proactive and self-tuning environments and devices to seamlessly augment a person's knowledge and decision-making ability, while requiring as little direct user interaction as possible. The realization of this vision requires that distributed context manipulation be conducted in an effective and efficient manner. In these environments, devices and associated software of diverse software and hardware providers will pervade everyday life. We propose a UML Profile for modeling such PCE including context modeling and distributed knowledge manipulation.

GRID of heterogeneous computing units is increasingly used to perform distributed computing operations where local resources are globally shared to perform some function. Resource management for highly heterogeneous and dynamically evolving networks where it is difficult to predict what resources are or will be available at some point in time constitute one of the issues. The GRAPPA approach provides the solution for the above difficulty and considers them as different behaviors (or configurations) of the same underlying system.

Retailers are constantly in search for ways to enhance customer satisfaction so as to differentiate with the competition and increase revenue. This paper describes an in-store commerce server implementation that leverages pervasive computing technologies to redefine the in-store shopping experience. The server evolves the existing point-of-sale systems into a store integration platform complete with reusable in-store solution building blocks. The paper illustrates how customer touch points such as cart-mounted Web pads can be supported to enable location-sensitive, personalized shopping assistance, and incremental self-checkout. New collaborative shopping paradigms can be created by service-oriented process choreography with other sales channels.
