Content-based routing using multicasting for Vehicular Networks

Of late, Vehicular Networks (VANETs) applications is capturing major importance in the research field. Efficient dissemination becomes demanding when information explosion overloads the network. Development of an efficient event disseminating framework is necessary to support such highly dynamic, self-organizing networks. Event broker middleware provides seamless messaging in heterogeneous environments making it most suitable for VANETs. In light of this, the paper proposes an approach that accumulates content-based subscriptions in a compressed structure using Binary Decision Diagrams (BDDs) encoding and extends VANET´s Spatio-temporal Multicast Routing Protocol (SMRP) to use the framework from middleware tier to build a most favourable dissemination mesh.
