Abstract

In the ubiquitous computing system fast and reliable event delivery is important to properly adapt to the dynamically changing environment. Such requirement could be satisfied by message-based middleware based on the publish/subscribe model. In this paper we propose a scheme that allows reflective filtering through the reasoning process. The objective of the reflective filtering is to prevent waste in the space of the event queue of the event channel due to useless events and reduce the network load. Performance evaluation reveals that the proposed scheme displays a significant improvement over the existing event service, Java messaging service (JMS) and omnievent service, in terms of event delivery time.
