Abstract- A network of vehicles in adhoc nature i.e. Vehicular Ad-Hoc Networks (VANETs) are expertise and uses moving cars or some other vehicle eg: bus in a network as nodes to craft a system of mobile. Networks of Vehicles in adhoc nature turn every car or vehicle participating with a wireless router, allowing cars or buses to connect and craft a network with a spacious range. Networks of Vehicle in adhoc nature are developed for ornamental driving security and comfort of automotive users. When traffic occurs, it is obligatory to diminish the load of the beacon to keep definite quantity of the vacant bandwidth for the messages which are ED messages as they cart information which is time-critical of high importance. Therefore, the congestion control remains one of the most exigent problems of these networks. This paper surveys some techniques on congestion control, which are divided into three categories: Rate adaptation, Media access control which is (MAC) and trajectory based Forwarding schemes for VANETs.
