QoS-aware Web Service Selection based on Particle Swarm Optimization
Tongguang Zhang · Journal of Networks · 2014
Abstract—QoS-aware binding of composite services provides the capability of binding each service invocation in a composition to a service chosen among a set of functionally equivalent ones to achieve a QoS goal. Hence, service selection approach plays a very important role in service computing. However existing approaches little considered the computation time. In this study, we propose a fast QoSaware 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 lower time cost than other approaches in web service selection.
