Abstract: “Vehicular Adhoc Network (VANET) is an emerging field of networks which enables inter-vehicle communication. Reliability is one of the most important factors in VANET. Many times, the messages exchanged between the vehicles are emergency messages. It is very important that such emergency messages reach concerned vehicles in time otherwise the consequences might be disastrous. In this paper we study and compare reliability of two important protocols – AODV and DSR using ESTINET simulator in different traffic density scenarios. Finally we conclude which protocol performs better in different scenarios.”
