Vehicular Ad-hoc network is an emerging technique for the Ad-hoc networks and Intelligent Transport System (ITS).VANET is mainly used for avoiding the accident and shares the traffic information among the vehicles. For sharing the information among the vehicles many challenges are faced, because the VANET has dynamic topology and high mobility model. To resolve this problem, VANET has many types of routing methods and various routing protocols, but those routing protocols do not fully resolve the problem during the communication. In this paper we discussed, Position based routing method and Non-delay tolerant routing protocols, its advantages and issues.
