An Extended Topic-Based Pub/Sub Broker for Cooperative Mobile Services
Augusto Morales Dominguez, Ramón Alcarria, Edwin Cedeño, Tomás Robles · 2013
The convergence between the network and service levels in mobile distributed systems allows content distribution in the Internet of Things. Distributed executing tasks exchange control and data events for enabling service cooperation. Event correlation addresses the correct identification of received events and the message delivery to the accurate task. However, it still remains as a major issue in these systems. We propose an extended-topic based model that targets Cooperative Mobile Services through the publish/subscribe primitives. It contributes to solve the event correlation challenge in distributed event-based systems. Finally, we evaluate our model by implementing a topic-based broker with multi-topic intersection support.
