Abstract

The sudden increase in vehicular traffic and congestion on the highways become threatening to safety and efficient movement of traffic. As a result there is an ascending rate of accidents, which leads to exploiting new technologies e.g. wireless sensor network has become most reliable, safety and secured technique of these saddening and reprehensible statistics. This has motivated to propose a model and comprehensive approach to utilize Wireless Sensor Networks for vehicular networks. Vehicular AdHoc Network’s are the standard phenomenon to provide safety and for secured applications. It plays an important role as a part of intelligent transport system. It is a self-organizing AdHoc network where sensor nodes are deployed in large number. It increases safety and comfort for vehicles by making an efficient use of wireless communication between stationary nodes and the nodes under motion. In the proposed model, pressure sensors deployed in the vehicle senses the pressure continuously. On occurrence of accidents, the pressure increases above the threshold and informs the vehicles in the vicinity by the buzzer. Also it sends a notification to the specified receivers and base stations.
