Abstract:
In the highly dynamic context of ubiquitous systems, applications need to be continuously aware of QoS and QoC metadata to ensure their required level of quality. We present QoMonitor, a metadata monitoring system that receives syn-chronous and asynchronous requests from clients (a middle-ware system that supports ubiquitous applications), recovers metadata from several context providers, and sends them to the clients. We also present an evaluation of QoMonitor under a quantitative perspective, which aims to address the time for assessing QoS and QoC parameters and the time to completely reply to synchronous and asynchronous requests in the context of a health care application. The proposed monitoring system enables ubiquitous applications to focus on addressing the business requirements of the application and abstract away the burden of dealing with the complexities related to synchronous and asynchronous metadata monitoring.
