Abstract
An inventive method for data delivery in a multi-hop vehicular network with multiple vehicles and intersections is presented. The method comprises, at each source vehicle, initiating packet flow, labeling packets with destination coordinates and a current location, and forwarding the packet flow, and at each intersection, selecting a header vehicle, computing a backlog indicator and listening for broadcasts with a matrix and delay information, updating the matrix in accordance with the backlog indicator if the matrix is present, otherwise initializing the matrix, forwarding the packet flow, and broadcasting the matrix from the header vehicle. In one embodiment, selection of the header vehicle is performed based on random countdown and vehicle ID. The method converges to the optimal (lowest latency) state irrespective of the initial starting point of the network and continues to tend towards the optimal state even as the network conditions alter.
