A Mobile Agent-Based Approach for the UMTS/VHE Concept

Proceedings - International Conference on Pervasive Services, ICPS '05, 2005

One of the most important aspects in the upcoming generations of mobile wireless telecommunications infrastructure is the Virtual Home Environment (VHE) a ubiquitous approach in the delivery of services. In this paper, we study the performance benefits of mobile agents for coping with the technical challenges associated with the VHE. We investigate the performance of mobile agents in terms of response time for service provision in a 3G network against a conventional solution. We base our experiments in an integrated, open and extensible agent-based VHE architecture by taking into account a variety of service use scenarios. Finally, we present our results.

A Personal Distributed Environment (PDE) embraces a user-centric view of communications that take place against a backdrop of multiple user devices, each with its distinct capabilities, in physically separate locations. This paper provides an overview of a Personal Distributed Environment and some of the research issues related to the implementation of the PDE concept that are being considered in the current Mobile VCE work programme.

Virtual Home Environment is a new concept that emerged in the context of the 3rd generation networks for mobile communications. The objective of this paper is to present the work that currently takes place in VESPER1, an IST project in the area of the VHE. The paper presents the VESPER project approach to the VHE architecture, its main components, the way they interact and the way this architecture will facilitate the creation of services embedded with the VHE concept. The paper presents also two demonstration services, their main functional features and how they use the VHE architecture defined in VESPER.

The mobility of terminals and users is a crucial issue in the open global system represented by the Internet. Supporting terminal and user mobility requires a middleware infrastructure capable of efficiently answering the needs of scalable resource discovery, of security and interoperability, of Quality of Service (QoS) monitoring and adaptation. Some proposals address mobility at the network level and some others focus on application-level solutions. By following the latter approach, the paper proposes the adoption of the mobile agent technology to model and implement mobility. In particular, the paper concentrates on the components and modules implemented in the SOMA mobile agent programming framework to specifically support terminal and user mobility. The SOMA tracing and discovery system extends the SOMA basic naming service to identify and keep track of all mobile entities in the environment. The SOMA QoS adaptation support exploits the functionality of the SOMA monitoring tools and permits to dynamically adjust service provision in response to the changing network and nodes conditions. These features are integrated in a mobility add-on module that pursues also the goals of security and interoperability when moving users and roaming terminals.

New advances in mobile computing devices allow us to think about new approaches such as a functional ubiquitous computer. In particular, it would be very useful for users to move from one place to another having all his data and applications available, in the same state, and without doing anything special (a real ubiquitous computer).

The emerging 3 rd generation services are provided through various types of networks and terminals. Roaming users rely on new kinds of wireless networks and terminals to offer mobility and make services available everywhere. The users' requirement for continuous access to personalized services from any place, transparently and independently of the underlying network technology and the terminal or point of access, was satisfied by the first VHE prototypes. The challenge in service engineering is now to make these services smarter by adding context management capabilities to them. In this paper we propose an enhanced framework for efficient context management in a VHE environment.

Addressing the needs of the mobile computing community in all its guises is one of the critical challenges facing the research community in the coming decade. Given the constraints under which mobile computers must operate, significant effort must be expended to ensure that the end user’s experience is satisfactory. In this paper, the selective use of intelligent agents as a means of augmenting the user experience through interfacing with the physical environment and anticipating user requirements is proposed.

A variety of concepts for the integration of services (VoIP, Unified Messaging) are either in development or have already reached the market. They aim for interworking of classical telecommunications and data communication services. On the other, they are realizing a universal access to services. A lot of basic problems in the area of service personalization have been solved. But at least one challenge is still there: providing several services to users keeping the peculiarity of each service alive.

Over the last couple of years we have been working on the development of mobile agents systems and its application to the areas of telecommunications and network management. This work path produced positive results: a competitive mobile agent platform was built, the run-time benefits of mobile agents were proved, and our industrial partners have developed practical applications that are being integrated into commercial products.
