VANET (Vehicular Adhoc NETwork) research field is growing very fast. It has to serves a wide range of applications under different scenario (City, Highway). It has various challenges to adopt the protocols that can serve in different topology and scenario. This paper presents a comparative study of the adhoc routing protocol in urban and highway scenario of VANET environments. The main objective of Vehicular Ad-Hoc Networks is to build a robust network between mobile vehicles so that vehicles can talk to each other for the safety of human beings.
