Abstract

Applications in distributed multimedia systems need to manage the levels of quality of services in environments that have wide variations of operation properties. So, most of the recent researches are directed towards the establishment of criteria that lead higher quality of services levels. For this, they consider the availability of resources in the current execution context. In this direction, this work has been focused on criteria definitions that can subside decision-making processes which are related to dynamic evaluation and selection of properties and components. The intention is to keep the system operating in a consistent way by considering the established levels of quality. For this, the work considers the several experimental tests that have been conducted in a Cosmos framework based environment, where were analyzed different requirements such as loading and platform requirements.
