A New Approach to Manage and Disseminate Data in Vehicular Ad hoc Networks

Our work focuses on data dissemination in Vehicular Ad Hoc Networks (VANETs). Publish/Subscribe communication paradigm enables efficient method of information spreading in a VANET environment. In this paradigm, the broker is a mediator between the publisher and the subscriber. These brokers can be fixed on the roadside or mobile in a specified area. In this paper, we propose an enhancement to an existing approach to improve its performance, this approach has used the mobile brokers, which are connected to Internet and form a Distributed Hash Table (DHT) based on broker overlay.
