Nowadays, we are assisting to a paradigmatic shift for the development of web applications due to the pervasive distribution of their components among a lot of servers, which are dynamically interconnected by web links. As a consequence, the application logic is often defined by exploiting workflow languages since they are more suitable to address the complexity of these new running environments....
Web services represent a step forward in enabling collaborations between various entities on the web and in overcoming the interoperability problems that may appear. This study proposes an adaptive fuzzy detector to detect the R peak correctly. This paper describes the various auction processes that could be entered into and, as an illustrative example, it describes how web services execution environment...
Web searching is a basic daily activity for computer users. However, providing the appropriate keywords for a search is not easy, especially when a user is unfamiliar with the subject being searched. Web services provide a suitable technical framework for making business processes accessible within enterprises and across enterprises, so that they have promoted a new paradigm of a business process...
In this paper, we present a framework to facilitate reputation-based service selection with reputation management, which has three key features. First, we use a structured overlay network as the decentralized service repository system for improved efficiency. Second, we propose an adaptive QoS-aware service discovery approach. Then, we present a service-oriented distributed reputation assessment algorithm...
From the analysis of some hard drawbacks faced with system service and composite service management today, a novel multi-agent-assisted and WS-management-based composite service management scheme: MWS-MCS is introduced in this paper. Firstly, we propose model architecture of this scheme. The prototype system had proved the feasibility of this design scheme. At last, we conclude this paper and analyze...
Globalization leads to an efficient new business paradigm generally known as collaborative virtual enterprise (CVE) which demands flexible service orchestration and robust workflow execution. As two major service orchestration strategies, OWL-S and BPEL have their own strength and deficiencies. To meet the challenge in CVE, in this paper, we propose a workflow execution system (WES) that takes advantage...
Self-healing in workflow is becoming prominent because of the increasing software complexity. In order to support robust workflow execution, in this paper, we propose a self-healing mechanism to replace the faulty service dynamically. It is based on our previous research work -workflow execution system (WES). The OWLS2BPEL Mapper in WES is further enhanced to embed the self-healing mechanism into...
