C-DRIVE: Clustering Based on Direction in Vehicular Environment

In this paper we propose a direction based clustering algorithm to disseminate the information amongst vehicles. This protocol can be used to realize efficiency applications in VANETs such as adaptive traffic signal control by estimating the density of vehicles on a given road. C-DRIVE uses the direction of the vehicle to optimize the data dissemination during the formation of the clusters and hence facilitating for better utilization of the available bandwidth. The simulations show that the proposed protocol reduces the number of broadcast packets being sent on the network. We also find that the protocol is efficient in terms of overheads during the cluster formation.
