Abstract

The modern generation VANET systems are denser and it supposed to handle high traffic rate as well as frequent interruption in connection. Power and bandwidth should be utilized efficiently. At the same time, the VANET nodes must be simple, cheap, smaller in size and efficient enough to handle traffic. In VANET environment, the quality of received signal level degrades due to path-loss and shadowing effects from various obstacles in propagation path. Flooding mechanism in VANET unconditionally floods data packets in all the directions which again harm network in terms of bandwidth wastage, collision, energy consumption. To improve reliability of communication Effect of flooding can be suppressed by eliminating or dropping certain nodes. In VANET system Vehicles need to communicate with the other node, for that node continuously sending RTS-CTS signals. As if number of signals increases, there is high probability of collision. Collision damages data packets .so it requires retransmission, this paper presents different routing protocols and approaches through which overhead can be reduced.
