Preventing vehicle crashes through a wireless vehicular sensor network

In this manuscript we propose a wireless sensor network (WSN) based solution allowing vehicles with merely onboard sensors to avoid frontal collisions in rural highways. Unlike the current solutions that rely on heavy infrastructure, in our vehicular traffic safety solution only tiny low-cost sensors are employed. It can thus replace the infrastructure-based systems in rural and suburban areas, where the deployment of such infrastructure is constrained. It can also serve as an alternative solution for unsophisticated vehicles that are not equipped with aboard computers and cannot take advantage of the current intelligent transportation systems and services.
