Hybrid Approach for Routing in Vehicular Ad-hoc Network (VANET) Using Clustering Approach
Interest in vehicular ad hoc networks (VANETs) has grown over the last few years, particularly in the context of emerging intelligent transportation systems (ITS). Vehicular ad hoc networks (VANETs) are highly mobile wireless networks that are designed to support vehicular safety, traffic monitoring, and other commercial applications. However, efficient routing in VANETs remains challenging for many reasons, e.g., the varying vehicle density over time, the size of VANETs (hundreds or thousands of vehicles), and wireless channel fading due to high motion and natural obstructions in urban environments (e.g., buildings, trees, and other vehicles). Within VANETs, vehicle mobility will cause the communication links between vehicles to frequently be broken. Routing becomes an important issue in VANET. If the network has very less vehicle then it becomes more challenging to send a packet from source to destination. In such scenarios efficient routing plays an important role. With efficient routing technique we can provide communication in network even if the density of vehicles in the network is low. We provide a routing algorithm which works on a hybrid scenario, i.e. it will have both static and dynamic infrastructure. The approach used is Cluster based routing which will help in transmitting packets even in a network with low vehicle density.
