Effective QoS Aware Web Service Composition in Dynamic Environment

Nowadays, several web services composition approaches, each considering various aspects of the composition problem, are known. Consequently, a lot of attention shifts to the performance issues of web service composition. This paper presents an effective QoS aware composition approach. Our work focuses to its performance, which is studied also in dynamically changing environment, where new services are deployed, some services are removed, or the QoS characteristics change in time. We analyze the impact of the need to manage these changes to the sojourn of the composition query in the system. The experiments show that the proposed composition system is handling these changes effectively and the sojourn time is not significantly affected.
