Abstract:
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.
