The vehicular-adhocnetwork (adhocNet) termed to be prominent way of information transfer using vehicles plays a significant role in the development of the intelligent and safe transportation, to avoid the unwanted causalities. They provide a more comfortable way of driving and travelling; by providing the complete details entailed for the travel, utilizing the nearby vehicles and the roadside unit. But due to certain security issues arising in the information transmission by the conventional methods of the vehicular- adhocNet, the conventional method of vehicular- adhocNet seems to be inefficient. So the paper proposes a modified vehicular- adhocNet that replaces the cloud computing in the place of the road side unit to provide a enhance security in the information transmission, thus improving the performance of the vehicular- adhocNet as a whole. The performance evaluation of the proposed method using the NS-2 on terms of the improve security, delay and the throughput proves its significance.
