Measurement of network Quality of Service (QoS) has attracted considerable research effort over the last two decades. The recent trend towards Internet Service Providers (ISP's) offering application-specific QoS is creating possibilities for more sophisticated QoS metrics to be offered by ISP's in service level agreements. This in turn could be use...

This document outlines the ENVIROFI data and meta-information specifications. The approach we have adopted is to first analyse the domain specific data models, vocabularies, ontologies and metadata found in the ENVIROFI pilots. This analysis is supported in the appendix with examples of the data sources described. We then review the available metad...

The increased availability of context information and the widespread adoption of more and mote powerful devices creates the opportunity and desire for context-aware applications. In this paper we focus on a specific but important type of applications: workflow applications. Just like other applications, workflows too require context-aware capabilit...

Research results from industry-academic collaborative projects in service-oriented computing describe practical, achievable solutions. Service-Oriented Applications and Architectures (SOAs) have captured the interest of industry as a way to support business-to-business interaction, and the SOA market grew by $4.9 billion in 2005. SOAs and in partic...

An integrated approach to quality of service for content delivery using Web services includes quality definitions, user contracts, and fault monitoring.

Future complex architectures for Web-Services-based delivery of services and objects require applications able to deal with different levels of Quality of Service (QoS) and able to describe also the quality of the associated object. In order to allow applications adapting in front of degraded quality in a pre-determined way, all the nodes participa...

Process quality, as perceived by users, depends on both the service quality and on the quality of its delivered resources. This paper combines in a contract model the quality of the process and of the objects delivered through the process. The model is a tool for providers to formalize quality guarantees for their users. Besides contract modelling,...

Failures during web service execution may depend on a wide variety of causes, such as network faults, server crashes, or application-related errors, such asunavailability of a requested web service, errors in the orchestration of choreography of applications, missing data or parameters in an execution ?ow, or low Quality of Service (QoS). In this p...

The advent of Web services, new network technologies, and new devices gives new opportunities and imposes new requirements for the design and execution of adaptable processes. Processes can be composed using Web services, but their orchestration has to also consider users needs at runtime, where these needs are expressed as context information. Con...

Sommario Il Progetto PRIN Quadrantis si propone di modellare gli aspetti legati alla cooperazione degli e-Service concentrandosi sulle prob- lematiche legate alla QoS e sulle possibili azioni di recovery che, a valle di una diagnosi per determinare la causa del problema, possano imple- mentare politiche di adattivita. La modellazione degli e-servic...

BPEL only supports a strictly centralized and coordinated execution of Web service compositions, but this solution is clearly not the best option in many concrete cases. The conceptually monolithic BPEL process should be executed in a distributed setting, where each peer is only responsible for a fraction of the whole process and for the coordinati...

Web services are imposing as the technology to integrate highly heterogeneous systems. BPEL, the standard technology to compose services, assumes a single ”orchestrator” that controls the execution flow and coordinates the interactions with selected services. This centralized approach simplifies the coordination among components, but it is also...

Self-Healing is an emerging exigence for Information Systems where processes are more and more complicated and where many autonomous actors are involved. Self-healing mechanisms can be viewed as a set of automatic recovery actions fired at run-time according to the detected fault. These actions can be at infrastructure level (i.e., transparentl to...

The goal of the MAIS system is to provide support for flexible and adaptive execution of applications in a distributed, multichannel, mobile information system. In such a system, a fundamental requirement is an ability to describe the continuously evolving execution environment and user characteristics. Service requests are therefore satisfied by c...

New mobile technologies such as Bluetooth or Wi-Fi suffer from many limitations and problems, especially when they are used in combination, whereas they are quite stable in small networks. The lack of specialised mobile middleware requires new methods in the design and execution of mobile information systems. We propose a two-phase approach to mana...

Nowadays e-services are gaining strong momentum. The Web is a strongly connected environment and it is moving from being a simple collection of HTML pages toward a container of e-services. In an extremely competitive world, providers of e-service aim at satisfying user needs, providing enriched e-services characterized by high adaptivity to the con...

This trouble aspect affect also the design of Mobile Information System based on wireless networks. Our research focuses on the management of a business process in a mobile environment. This paper is about an ap...

Italian cultural heritage is one of the most famous in the world, but unfortunately is under risk of destruction. The Italian government has started a project to define the risk map of Italian cultural heritage (MARIS). Starting from this real example, we describe an example of a cooperative and mobile information system devoted to acquiring data a...

Service oriented computing is becoming the standard paradigm to support the creation of applications composed of ser- vices selected from a registry. Nowadays, we are assisting to the proliferation of standardized approaches to describe such services, but there is the general agreement of distin- guishing between the general characteristics of serv...

The increasing success of wireless technologies is sustaining the diffusion of mobile information systems, but the youth of the underlying technology and its peculiar characteristics are impacting the development of such systems. For example, the execution of business processes in such a context must cope with the variable and fluctuating bandwidth...

Nowadays the anytime/anywhere/anyone paradigm is be- coming very important and new applications are being developed in many contexts. The possibility of using applications along a wide range of devices, networks, and protocols raises new problems related to deliv- ery of services. Current academic and industrial solutions try to adapt services to t...
