QoS monitor as a service

Quality of web service becomes more and more interesting as a distinguishing criterion to select a unique web service from all candidate ones. The quality assessment issue, especially regarding the volatility of the web services environment, is one among the main challenges in this context. In this paper, we propose a service-based system for web services monitoring. Compared with other efforts in this concern, our proposal is closer to the client’s non-functional requirements, more accurate and extensible to support new quality attributes.
