Mobile nodes communicating in a wireless medium without a fixed backbone infrastructure form an Ad-hoc network for VANETs which are characterized by their node movement and application scenarios. Routing protocols target to achieve minimum usage of network resources with less communication time. Due to fast moving vehicles, dynamic information exchange and relatively high speed of mobile nodes, finding and maintaining routes is a very challenging task in VANETs. For these networks, packets travelling from sender to destination suffer huge packet loss and long delay due to congestion occurring in intermediate nodes. In this paper, a performance analysis is carried out on an Early Congestion Detection and Control routing protocol called EDAODV and the Ad Hoc On-demand Distance Vector Routing protocol AODV which has no congestion control mechanism for a network. We have done our simulations in NS2 and the results are compared among these protocols for increased number of nodes.
