Abstract

What we call the world wide web nowadays has its origins in a system designed to share and distribute information among scientists. It took less then a decade and "the web" evolved into an omnipresent medium for information sharing, communication and even collaboration and cooperation. A multitude of new standards, protocols, and services has been proposed, some of them became a success, others died even before they had the chance to lift up.

In this talk, we are going to reflect on the evolution of the web from an information medium over a communication medium up to a wide-spread cooperation medium used in many application domains. We will specifically address the question whether this growth in size and scope is adequately met by the offered protocols and services from a functional as well as qualitative and quantitative point of view.

Supporting such cooperation (beyond pure communication) via shared artefacts, multi-user awareness and virtual presence raises a variety of both, technical as well as organizational questions.

From a technical point of view, the success of the web as cooperation medium will depend on the quality of service (QoS) level at which it can be operated. The gap between the QoS demands of cooperative applications and the QoS that the underlying technologies are able to deliver raises the need for QoS modeling and evaluation. In the main part of this presentation, I will focus on performance evaluation techniques based on a user-oriented approach for characterising the load in cooeprative environments as a potential solution to this problem. Automated mechanisms for translating from a user-oriented view of the workload in the system to a resource oriented view will be presented and their importance for QoS mechanisms such as scheduling, admission control, loadsharing, flow identification and traffic engineering will be assessed. Traditional traffic modelling approaches (from queueing theory and analytical performance engineering) will be contrasted with innovative techniques, including probabilistic attributed context free grammars as well as an event-based hierarchical modelling framework, which supports the integration of various modelling approaches (e.g. user behaviour graphs, markovian models, or process algebras). Appropriateness of this framework will be demonstrated in an application scenario, where a simulation model is used to evaluate QoS in terms of user satisfaction in a video-conferencing environment.

Adoption Issues for Cloud Computing

Prof. Won Kim
Lifetime Professor and IT Vice President
Kyungwon University

Abstract

Cloud computing is already being used by tens of millions of people in various manifestations, including free email services and free office productivity applications, and subscription-based SaaS services and managed computing services. Cloud computing allows users to use only a Web browser to receive computing services from remote data centers via the Internet. Users only need to pay for the services they actually use, and in principle, do not need to maintain on-premises computing facilities. It appears that a wide adoption of cloud computing in the foreseeable future is inevitable, and its adoption will bring about a sea change in the pricing and distribution practices for both software and hardware. There are, however, various issues that will impede adoption of cloud computing. Most of them can be solved. I will discuss the status of cloud computing today, various adoption issues, and architecture for enterprise cloud computing. I will also outline various research issues in cloud computing.

An Architecture for Traffic Incident Detection

Abstract

Road and traffic safety can be improved if the drivers have the ability to see further down the road and can be informed of relevant traffic events, including collisions and slow-downs. The recently proposed VANETs (Vehicular Ad hoc Networks) are expected to enable both vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications. Virtually all the papers published in the literature assume that V2V communications will rely on a strong roadside infrastructure. Unfortunately, the roadside infrastructure, is very likely to be the target of theft, vandalism and other similar activities that will jeopardize their intended functionality. Worse yet, one can easily contemplate a scenario where the roadside infrastructure may be hacked and injected with malicious code, rendering it not only useless but, downright dangerous.

However, all the VANET systems proposed thus far are afflicted with serious security and privacy problems. Indeed, the way current systems are set up, the driver of a car that participates in the traffic will not be able to preserve their privacy and may be subject to impersonation or Sybil attacks. The problem stems from the fact that V2V communication can be traced back to an individual car. Even if several pseudonyms are used, detecting the true identity of the driver and, therefore, invading their privacy appears to be unavoidable.

In a sharp departure from the common wisdom we propose to look at vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications from a different perspective. Instead of relying on the roadside infrastructure that is vulnerable to attacks, we propose to embed in the asphalt covering the surface of the roads sensor belts. Each belt consists of a collection of pressure sensors, optionally equipped with piezo-electric elements. The belts can detect and interact with passing cars.

In this talk we discuss in detail NOTICE our architecture for traffic incident detection and show that it can be easily extended to cover many problems of interest in infotainment and peer-to-peer content delivery. One important application of NOTICE is with planned evaluations when optimal use must be made of available transportation resource.

Organizing Web Services to develop Dynamic, Flexible, Distributed Systems

Dr. F. Dignum
Intelligent Systems Group
Institute of Information and Computing Sciences
Utrecht University
THE NETHERLANDS

Abstract

Web services are increasingly behaving as nodes in a digital, dynamic ecosystem. On the one hand, this new situation requires flexible, spontaneous and opportunistic collaboration activities to be identified and established among (business) parties. On the other hand, it also requires engineering approaches able to integrate new functionalities and behaviours into running systems and active, distributed, interdependent processes. In this paper we present a multi-level architecture, combining organisational and coordination theories with model driven development, for the implementation, deployment and management of dynamic, flexible and robust service-oriented business applications.
