ABSTRACT In this paper, we describe a new route discovery technique known as scalable routing technique. This technique enhances the performance of the routing protocol density aware routing using road hierarchy (DAR-RH), which involves a route discovery procedure using Dijkstra algorithm before transferring data from source to destination. When DAR-RH is used in large road network scenarios the time complexity increases as Dijkstra algorithm considers all road intersections for route discovery. The solution proposed in this paper minimizes the road intersections to be considered for route discovery by dividing the city in terms of road hierarchies. By restricting Dijkstra algorithm to act on necessary data instead of entire city data shows significant performance improvement and effectiveness of our proposed technique when incorporated in DAR-RH.

ABSTRACT Intervehicular communication (or vehicular adhoc networks, VANET) mirrors as one of the emerging technologies for road safety and comfort applications. However the use of this technology is limited due to the lack of an efficient routing protocol. In this paper we propose density aware routing using road hierarchy (DAR-RH) which is based on realistic road topology. DAR-RH exploits the available road hierarchy information to transfer data from source to destination. In the proposed solution two routes are maintained; in case of failure of the primary route, an alternative route is maintained at a higher hierarchy under sparse network conditions. The proposed scheme is found to exhibit significant performance improvement in comparison with a geographic routing protocol under similar conditions.

Vehicles are envisioned to become real communication hubs in the near future, thanks to the growing presence of radio interfaces on the cars as well as to the increasing utilization of smartphones and tablets by their passengers. In such a context, simulation remains the mean of choice for the evaluation of large-scale deployments of new vehicular networking solutions. In order
