Abstract
Vehicular Ad-hoc Network (VANET) is an integral part of Intelligent Transportation System (ITS), in which moving vehicles communicates with each other in autonomous and asynchronous fashion. Speed of vehicles is responsible for dynamic change in topology; due to this efficient and scalable information dissemination is a major challenge in VANET. Publish/Subscribe communication approach provides independence from synchronization of time, space and other information between vehicles or RSU’s, which makes it most suitable for VANET like environments. But only publish/subscribe approach is not sufficient for efficient communication because it generates huge amount of packets for dissemination; due to this network load is increases. In this paper, we propose publish/subscribe methodology using clustering for information dissemination in VANET. In our approach, we assumed a VANET consisting of road side units and vehicle nodes where all vehicles can elect their cluster head from its neighbor vehicle nodes; each vehicle can take the role of publisher, subscriber or broker but cluster head is its ultimate place holders for publications and subscriptions with in cluster. Every major crossing of city is equipped with road side units that act as ultimate place holders for publications and subscriptions given by cluster head. Simulation results indicate that our approach performs well which suggests the applicability of our approach.
