The vehicle-Adhoc Networks are the specific type wireless adhoc networks, framed using the group of vehicles supporting the “on the fly’ communication between vehicles on the roadside. This is basically developed to handle the traffic in an intelligent manner avoiding the unnecessary time elapse, discomfort and the fatalities during the travelling and in turn improvise the convenience in the transportation providing a continuous traffic movement. But certain emergent situations such as the natural disasters, accidents, damaged roads, sudden break down of the vehicles and the appearance of the emergency vehicles disturb the regular traffic flow and safety of the on road vehicles. To ensure the safety of on road vehicles and elude the collision of the vehicles that take place due to improper communications or communication attacks, the paper puts forth an effective routing protocol with collision avoidance, (ERPCA) to identify vehicles with the reliability to transfer information on time and evade the discomforts in travelling. The evaluation of the ERPCA with the network simulator-2 evinces the improvement in the performance of the vehicular-adhoc networks

Vehicular Adhoc Networks

AbstractVehicular networks that deal with sharing of information among vehicles are gaining popularity among the automobile industry as well as the researchers. These networks are prevalent under the umbrella of Intelligent Transportation Systems (ITS) and deal with data that belongs to either the emergency category or the entertaining category. In case of emergency services, it is clear that - earlier the reception of information, lesser the commotion. The objective of this work thus has been the reduction of the end to end delay when video files are exchanged among vehicles during intersessions. The set objective is accomplished through the design and development of the technique “Instantly Decodable RaptorQ Inter-Sessions” (IDRQIS) for Vehicular Adhoc Networks and the results obtained show that this outperforms the existing popular techniques – the Network Coding and RaptorQ when applied independently to the same environment. This technique can also be applied to the upcoming unmanned vehicles.

Adhoc networks as the name suggests is framed for a specialized reason using the volunteering devices available near the source to destination, utilizing the devices in between the source and the destination as the relaying nodes. Several methods were framed to optimize the performance of the wireless adhoc network to retain the energy level of the devices in turn to extend the lifetime of the devices. The cluster based routing seemed to be very promising in terms of energy efficiency, throughput and delay. These cluster based adhoc networks are very much exposed to security breaches as they are not aided with sufficient security. The conveyance taking place between the head of the cluster to base station is often affected by the many attacks from different sources by altering the information or hacking the information. So the paper puts forward the verification code for every data transmitted from the head of the cluster to the base station. The proposed method is validated using the network simulator-2 in the terms of throughput, energy consumption and security in data conveyance and compared with the prevailing methods that bare authentication.
