QoS Prediction based on temporal information and request context
Service Oriented Computing and Applications (SPSOCA), Volume 15, Issue 3Pages 231–244https://doi.org/10.1007/s11761-021-00322-4AbstractDue to the complex and dynamic nature of the Internet, the status of services and their qualities (QoS) change frequently. It is thus important to predict the service quality accurately at runtime from the user’s perspective. Traditional service ...
