摘要： A system and method for increasing transmission concurrency amongst communicating vehicles using UWB radio-based communication is presented. The method comprises dividing an area around a sending vehicle into transmission areas, and, for each transmission area, broadcasting a message from the sending vehicle, waiting for a time, and when a not clear to send response is not received, sending information to the transmission area, and the information being sent using a time-hopping sequence based on a location and seed in the message. The message can also have a frame length and a target region. The method can also comprise determining, when a no- send is received, whether the no-send was in response to the message from the sending vehicle, and when the no- send is not in response to the message from the sending vehicle, sending the information to the transmission area. The system and method can be used for active-safety vehicle communication.

摘要： A method for distributed traffic navigation in a vehicular network is presented. At each vehicle entering the network, information associated with the vehicular network is acquired and stored, and destination addresses are broadcasted as route requests. At each vehicle in the network, the stored information is updated through vehicle to vehicle communication. At each junction, a header vehicle is selected for listening for broadcasts to determine the presence of a matrix. If the matrix is not present, the matrix is initialized based on the stored information of the header vehicle. The header vehicle further estimates travel time on the road segments based on the matrix, calculates a backlog indicator based on the segment travel time and the route requests. The header vehicle further updates the matrix and generates a route based on the matrix. The matrix is broadcasted from the header vehicle.
