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...

As the deployment of Web services increases in complex business application integration, it is becoming inevitable that several Web services may have the same or similar functionalities each holds different Quality of Services(QoS). In this context, it is becoming a challenge for Web services developers to select most pertinent services for their businesses. In this paper, we suggest a novel me...

Ubiquitous Quality of Service(QoS)-aware applications, such as e-business or multimedia delivery are becoming available anywhere anytime. In the past decade, also QoS-oriented middleware services, assisting QoS-aware applications with different aspects of QoS provisions, have been proposed. Assuming the availability of these middleware services, in this paper, we present the application to midd...

This paper explores the issues related to developing a transparent Quality of Service (QoS) evaluation for wireless services and distributed applications. The objective of the paper is to show the importance of QoS evaluation suited to end users’ interests. A Mobile Agent QoS architecture is defined and the model is presented and evaluated through simulations.

  Network and processing overhead associated with web services is a significant challenge to its performance. As a result, web service providers often announce a service level agreement. This ensures that consumers, who pay for the service, can get the service at a given quality level. In this paper, we study the competition between two providers offering functionally the same web services, whe...

Ranking and optimization of web service compositions are some of the most interesting challenges at present. Since web services can be enhanced with formal semantic descriptions, forming the ”semantic web services”, it becomes conceivable to exploit the quality of semantic links between services (of any composition) as one of the optimization criteria. For this we propose to use the semantic si...

This paper brings a QoS (Quality of Service) assessment model which can estimate voice and video quality. Based on the proposed model, speech or video quality is computed with regard to congestion management QoS configuration in the network and its level of total utilization. The contribution of this paper lies in designing a new mathematical model capable of predicting the quality of multimedi...

The current competitive environment in mobile communication services in an increasingly mature market requires service providers to offer their communication services at rates attractive to their customers while at the same time offering reasonable service quality. As quality-of-service (QoS) is tightly coupled with communication system infrastructure investments, finding the right balance betw...

Web services have the potential to offer the enterprises with the ability to compose internal and external business services in order to accomplish complex processes. Service composition then becomes an increasingly challenging issue when complex and critical applications are built upon services with different QoS criteria. However, most of the existing QoS-aware service composition techniques ...

Clustering has been proposed in numerous researches on web services due to its ability in enhancing computational efficiency. The objective of this paper is to present a review on web services clustering and to propose fuzzy clustering of web services’ based on quality of service (QoS). A total of 49 manuscripts, collected from ISI, SCOPUS and Google Scholar indexing databases, were critically ...
