Abstract

Recent trends in computing have been driving the demand for mobile multimedia applications, specifically distributed virtual environments (DVEs). These applications must deal with the variable resource availability of both connection and client device in order to achieve real-time event communication. Relevance-based event filtering is used to explore event stream adaptation in response to variable QoS. Results show that the performance gains from such adaptation are inconsistent due to the irregular nature of event communication. Increased reliability is proposed through dynamic consideration of the resource requirements of the various adapted event stream solutions.
