Thispaperprovidesaviewaboutemerging communication technologies based on wireless sensor networks: current research and future applicationsanddescribes the additional sources and guides us for the application of this blue tooth technology in avoiding accidents in our daily transport. The Bluetooth protocol can be used forcommunication among vehicles equipped with Bluetooth devices. This work presents an approach to increase the safety of road travel using theconcepts of wireless sensor networks and the Bluetooth protocol. We discuss how vehicles can form mobile ad-hoc networks and exchange datasensed by the on-board sensors. The fusion of these data could give a better understanding of the surrounding traffic conditions. The feasibility ofusing Bluetooth for data exchange among vehicles is evaluated. Coverage area and probability of detection plots for isotropic and non-isotropicsensors are analysed to study their use to avoid potential dangerous situations in traffic.
