In semantic web service composition, the selection can also be performed after negotiating with all the discovered service providers and the negotiation-agreements generated from the negotiation can also be used in the selection process. This paper presents a semantic web service selection and composition model based upon this concept. The paper presents multi-agent negotiation based semantic w...

Resource brokering is a crucial activity in Grid infrastructures and other environments with dynamic resource selection. The mediation between resource requirements and available resources relies on adequate resource description, which becomes a special challenge when the resources are (Grid) services. In addition to the description of service semantics, service quality is another useful select...

Service selection has been widely investigated as an effective adaptation mechanism that allows a service broker, offering a composite service, to bind each task of the abstract composition to a corresponding implementation, selecting it from a set of candidates. The selection aims typically to fulfill the Quality of Service (QoS) requirements of the composite service, considering several QoS p...

Web services today are among the most widely used groups for Service Oriented Architecture (SOA). Service selection is one of the most significant current discussions in SOA, which evaluates discovered services and chooses the best candidate from them. Although a majority of service selection techniques apply Quality of Service (QoS), the behaviour of QoS-based service selection leads to servic...

An elitist selection adaptive Genetic Algorithm is presented to select an optimal cloud service composite plan from a lot of composite plans on the basis of global Qualityof-Service (QoS) constraints. In this Algorithm, some strategies are provided to improve convergence and population diversity and raise fitness result. These strategies include an elitist selection strategy, an individual sele...

It is imperative to provide service consumers with facilities for selecting required web services according to their Quality of Service (QoS). Several heuristics, which are local adaptation preemptive strategy, elitist perturbation guiding strategy and global tournament strategy for directed local fine-tuning, and a hybrid clonal selection algorithm (CSPLPT) are proposed for QoS-aware web servi...
