An Effective QoS-aware Web Service Selection Approach

摘要

Service computing provides the capability of binding each service invocation in a composition to a service selected among the same function attributes but different QoS attributes to achieve a QoS goal. Hence, service selection approach plays a very important role in service composition. However existing approaches little considered the computation time. In this study, we propose a effective QoS-aware web service selection approach. This approach adopts a particle swarm optimization algorithm select the most service with users' QoS requirements Experimental results show that our approach can find best suitable services with low time cost in web service selection.
