Developers of distributed multimedia applications face a diversity of multimedia formats, streaming platforms and streaming protocols. Furthermore, support for end-to-end Quality-of-Service (QoS) is a crucial factor for the development of future distributed multimedia systems. This paper discusses the architecture, design and implementation of a Quality of Service (QoS) aware middleware platfor...

With the development of service-oriented computing, more and more Web services are provided for users. However, there are situations that services or service processes cannot meet users’ requirements in functional QoS dimensions (e.g., translation quality in a machine translation service). Meanwhile, the emergence of crowdsourcing makes various types of tasks done in more and more efficiency wa...

Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...

The ability to guarantee various levels of service quality is an important feature of ATM networks. The mapping of the quality of service (QoS) concept of the fixed ATM network to wireless ATM access networks is currently being researched. The specific characteristics of the radio transmission will require some extensions and modifications of the ATM traffic management functions. We discuss the...

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...

Cloud Computing is a promising computing paradigm that provides flexible, Internet-accessible resources allocation on demand on a pay-as-you-go basis. With the growth and expansion of Cloud services and participation of various services providers, the description of quality parameters and measurement units started to diverse and sometimes contradict. Such ambiguity does not only result in the r...

Given the importance of QoS (quality of service) properties for distinguishing between functionally-equivalent services and accommodating different user expectations, a number of QoS estimation approaches have been proposed, utilising the observation history available on a service. Although the context underlying such previous observations (and corresponding to both user and service related fac...

Forthcoming applications, especially in the multimedia area, require communication services with guaranteed quality of service (QoS). In order to guarantee a certain quality of service, supporting mechanisms must be applied inside the communication system. Additionally, due to dynamic changes in the network, it is crucial to monitor continuously the achieved quality of service during data trans...

Designing of the composite services with desired quality is an interesting challenge in web service environments. In a QoS-aware web service composition, appropriate services with acceptable quality are selected among several functionequivalent candidate services. The selection is performed in such a way that creates a composition with optimal quality which can satisfy user’s constraints. In th...

Nowadays, Value Added Web Services (VAWS) are becoming a hot spot for web services providers. Quality of Service (QoS) support in VAWS is an important issue. The need for providing and assuring an acceptable level of QoS is the objective of most of service providers. Service providers compete in satisfying requirements of potential clients by providing QoS support of VAWS. In this work, we prop...
