A Content-Based Publish-Subscribe Routing Protocol in Mobile Ad Hoc Network

The development of distributed application in mobile ad hoc network faces great challenges. Accordingly, it has important significance to introduce the content-based publish/subscribe middleware. First this paper defines subscription language and event model containing event type domain. Then it proposes a novel content-based routing protocol which establishes an optimized dynamic multicast mesh and propagates events only to the matched subscription nodes so that unnecessarily propagation of events are confined. Based this protocol, an efficient content-based publish/subscribe system can be constructed. The experiment results show that the protocol can decrease the total cost of the network, save more bandwidth, improve the scalability and performance of the system.
