Proteus
We here present Proteus, a topic-based publish/subscribe system that employs gossip based communication.
Proteus is different from the existing systems as each topic in Proteus is divided into subtopics and users therefore subscribe to the topic of interest. The middleware manages the propagation of events in the topic hierarchy i.e. a process that subscribes to a topic T is implicitly subscribed to all subtopics of T in sense that it receives all events published at T or any of subtopics without even being aware of most of the subtopics of T.
