Vehicle Assisted Data Delievery Technique To Control Data Dissemination In Vehicular AD - HOC Networks (Vanets)

Multi-hop data delivery through vehicular ad hoc networks is complicated by the fact that vehicular networks are highly mobile and frequently disconnected. To address this issue, the idea of helper node is opted, where a moving vehicles carries the packet until a new vehicle moves into its vicinity and forwards the packet. Different from existing helper node solution, use of the predicable vehicle mobility is made, which is limited by the traffic pattern and the road layout. Based on the existing traffic pattern, a vehicle can find the next road to forward packet; a vehicle can find the next road to forward the packet to reduce the delay. Several vehicle-assisted date delievery (VADD) protocol is proposed to forward the packet to the best road with the road with the lowest data delivery delay. Experiment results are used to evaluate the proposed solutions. Results show that the proposed VADD protocol outperform existing solution in terms of packet delivery ratio, data packet delay and protocol overhead. Among the proposed VADD protocols, the Hybrid probe (HVADD) protocol has much better performance. In this Solution the helper node technique is provider with which the helper node will contain destination node path and the path in routine table continuously changes with the help of helper node technique.
