Service-Oriented Computing (SOC) increasingly gains momentum in academia and industry as a means to develop adaptive distributed software applications in a loosely coupled way. Software services, as the main entities in SOC, have some distinct properties such as platformindependence or a uniform interface description enabling an easier integration and use within and across organizational bounda...

One of the salient features of Service-Oriented Architectures is that services can be deployed and removed at runtime. But service replacement and management for service processes is a demanding task in complex IT-Systems, especially under additional constraints like optimizing the Quality of Service of a service process. A self-managing system is desired but missing. We have already achieved s...

The CORBA Event Service specification lacks important features in terms of quality of service (QoS) characteristics required by multimedia information. The main objective of the work described in this paper is to augment the standard CORBA Event Service specification with a set of extensions, to turn it into an adaptable QoS middleware multimedia framework. To meet this, some extensions to the ...

Preparing an open environment for dynamic composition and recomposition of services requires standardized technologies for building, deploying, and running software systems. One key challenge in this respect is how to compose services and orchestrate the service collaboration to best fit the specified behavior, both in terms of functionality and quality. In this paper we present an approach for...

Continuous care models for chronic diseases pose several technology-oriented challenges for home-based continuous care, where assistance services rely on a close collaboration among different stakeholders such as health operators, patient relatives, and social community members. Here we describe Emilia Romagna Mobile Health Assistance Network (ERMHAN) a multichannel context-aware service platfo...

In a previous column, I discussed how to build distributed systems from quality-of-service (QoS)-aware software components.1 I also described a design by which individual components can engage in QoS negotiation and perform admission control so that new incoming requests don’t violate committed QoS requirements.2 But what happens in a distributed application made up of several QoS-aware compone...
