The number of web services available on the Internet has grown rapidly. Service consumers face a hard decision over which service to choose among the available ones. Security holds a key after various vulnerabilities have been exploited by attackers on number of notable web services. This paper carries out a survey on how security has been expressed and promised for web services, through both the...
The reduction of energy consumption in base stations becomes popular recently. However, it is difficult to reduce energy consumption under the constraint of Quality of Service (QoS). In this paper, we propose a novel energy aware control method to adjust the radius that the base station provide the service in wireless downlink systems, the optimal radius of the base stations provide service could...
Although quality requirements (QRs) are considered as being of crucial importance in today's service-oriented systems, existing approaches almost exclusively deal with QRs from the service providers' perspective (namely late QRs). The motivation for this paper is to address the analysis of QRs from the service customers' perspective (namely early QRs). The work presented in this paper focuses on the...
QoS-aware service composition intends to maximize the global QoS of a composite service while selecting candidate services from different providers with local and global QoS constraints. With more and more candidate services emerging from all over the world, the network delays often greatly impact the performance of the composite service, which are usually not easy to be collected before the composition...
The component service in Web service composition may fail or degrade in QoS thus needs to be replaced. In this paper, we propose a novel approach for services replacement of the composition. The target service could be replaced individually, or it could be replaced with its related services in the composition as a whole by a more complex service. In this way, far more choices will be available to...
The authenticity of advertised QoS for Web services is of particular relevance during service discovery and selection. Reputation of a service is often used as a measure of its trustworthiness. Currently, reputation is usually computed from the users' feedbacks and represents a snapshot for the interactions in a past time slot. However, in an open environment, reputation is a volatile property, which...
There are more and more Web services used in collaborative learning, hence it has become increasingly important to locate proper Web services in an accurate and efficient way. In this paper, an annexed algorithm, called eLSDAUS, is proposed to improve the existing semantic-based matchmaking algorithm. In the algorithm, we introduce and incorporate in a new factor - user satisfaction, which is the...
