Vehicular area network is having the criticality because of its public and dynamic nature. It combines the complexities of both the mobile network and sensor network. The associated challenges include the area limitation, scenario specification and routing constraints. In this paper, all the associated challenges to the vehicular ad hoc network are discussed. The paper has also defined the generation of effective route generation so that effective communication over the network will be performed. The author has discussed these routing approaches under the specification of strength and limitation associated with the scenario and criticality.
