    摘要： A method, simulator and program for simulating vehicular movement based upon user input parameters related to simulation topology and simulation vehicles including, but not limited to linear vehicular density. The simulator generates the simulation topology having a simulation area using the user input parameters, places a plurality of simulation vehicles within the simulation area at an initial placement using at least two input parameters related to simulation vehicle and the generated simulation topology; and determines movement of the plurality of simulation vehicles starting with the initial placement using a plurality of movement models. Each of the plurality of simulation vehicles has mobility characteristics generated using the plurality of movement models. When vehicle moves outside the simulation area, the vehicle re-emerges at a location within the simulation area. The vehicle re-emerges with new movement characteristics.

    摘要： A method for high rate data delivery in a multi-hop vehicular network comprises at each source vehicle, initiating a packet having a flow tag, assigning an identifier of the content and the current location to the flow tag, and forwarding the packet; at each destination vehicle, setting a flow request and broadcasting at the current intersection; further on movement, setting the flow request at the new intersection, and at each intersection, selecting a header vehicle at the intersection, computing backlog and congestion indicators and listening for broadcasts with a matrix and the flow requests at the header vehicle, determining if the matrix is present, updating the matrix in accordance with the backlog and congestion indicators if the matrix is present, initializing the matrix and estimating the delay on the outgoing road segments if the matrix is not present, forwarding the packet flow, and broadcasting the matrix from the header vehicle.

    摘要： 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.
