Description
Summary:Advancements in communications technologies are spurring a revolution within the United States transportation network. Short-range dedicated radio allows vehicles to communicate with each other within VANET. Up to date, tremendous efforts from government, academia and industry have made progress in designing and implementing several vehicular safety applications. Therefore, significant efforts have been made in designing lower-layer communication protocols for VANET. Also, Connected Vehicles (CV) concept is moving rapidly from the experimental phase into real-world deployments. Nevertheless, since all vehicles in range are shown as destination nodes, safety applications in VANET critically need an optimized way for effectively transmitting information to surrounding vehicles. To respond to this need, we propose in this paper a new Request-To-Receive (RTR) approach as a crucial step in the Basic Safety Messages (BSM) transmission process among vehicles incubating multiple safety applications. A new Data Element is proposed to be added to the basic safety messages data dictionary. Simulation results showed that RTR reduces the average number of transmitted Data Element when compared to the current situation.
