Qos-Aware Dynamic Composition of Web Services Using Novel Planning Based Approach

Abstract

Nowadays, web services are essential to all organization to build their business. But the major issue in web service is quality of service. Web service does not allow multiple processes in parallel with effective quality of service measures. In this paper, I suggest a novel planning-based approach for service composition instead of predefined workflow model. With the help of numerical and temporal features, the novel planning-based approach converts QoS-aware composition task for a planning problem automatically. Of an edge, with numerical optimization and logical reasoning to handle complex temporal planning problems, I have used existing one and a self-developed one including the state-of-the-art planners. While fulfilling different global QoS constraints, the outlook can find an optimal overall QoS value with composite service graph. With the help of large web service repositories, I have conducted great experiments on implementing it in a prototype system.
