A Destination Based Routing Protocol for Context Based Clusters in VANET

Today, vehicular ad-hoc network (VANET) is a hot research topic due to its many applications like collision avoidance, congestion road notification, parking lot availability, road-side business advertisements, etc. All these applications have hard delay constraints i.e. the messages should reach the target location within certain time limits. So, there must be efficient routing in VANET which meets these delay constraints. In this paper, two techniques are proposed to minimize the data traffic and delay in VANET. Firstly, a context based clustering is proposed which takes into consideration various parameters in cluster formation-location of vehicle, direction of vehicle, velocity of vehicle, interest list of vehicle [1] and destination of vehicle. Secondly, a destination based routing protocol is proposed for these context based clusters for efficient inter-cluster communication.
