Routing is an extremely challenging phenomenon because of its non-deterministic mobility
behavior, power energy and high velocity of automobiles. These kinds of system are self-
dependent and they are interconnected through internet within its infrastructure. The key
features such as multi-hop paths, node mobility, huge network, device heterogeneity,
congestion and bandwidth are the constraints in designing the routing protocols for VANET.
In this paper we focused on areas such as broadcasting and routing, security, quality of …
