摘要： A method for determining a transmission channel for multi-hop transmission of a data packet from a plurality of data channels in an ad-hoc network. The network includes at least one local peer group. Each local peer group has a plurality of moving vehicles as nodes. The method comprises steps of determining available channels for data packet transmission at each node, transmitting a first list of available channels to at least one other node, receiving, from the at least one other node, a second list of available channel for the at least one other node, creating an available channel table including the first and second lists of available channels, selecting a transmitting channel for a data packet based upon information in the available channel table, and advertising the selected channel to the at least one other node.

摘要： An ad-hoc wireless network with a roadside network unit (RSU) and a local peer group (LPG). The LPG is formed from a plurality of moving vehicles. The LPG includes a group header node (GH) for managing the LPG. The GH is elected from one of the moving vehicles. The LPG further includes group nodes (GN) designated from the remaining moving vehicles in a given area. Each of the moving vehicles, whether the GH or the GN, communicates with other using routing paths created based upon a first control packet broadcast from the GH and a second control packet broadcast from each of the GN. Each moving vehicle communicates with the RSU using a routing paths created based upon a beacon broadcast by the RSU and a reply signal from each of the moving vehicles. The RSU can also be a member of the LPG and act as GN or GH.

摘要： A method for transmitting data in vehicular network comprising determining a communication window between at least two nodes, grouping a plurality of fragments of content together into an aggregate fragment block, forwarding the aggregate fragment block to a target node and assembling the plurality of fragments into the content. The content is divided into the plurality of fragments. A fragment signature is generated for the fragments that contain fragment index information regarding each fragment. Each fragment is unambiguously identified by its signature. A number of fragments grouped into the aggregate fragment block is dependent on the communication window.

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 establishing and maintaining the network and a corresponding ad-hoc moving- device to moving-device network having a plurality of moving-devices grouped into a Local Peer Group (LPG) is disclosed. A group header node (GH) is selected from the plurality of moving wireless devices in the LPG. The GH controls and manages the LPG by broadcasting a plurality of control messages, including a heartbeat message at a fixed interval. The LPG also includes at least one group node (GN). The at least one GN can communicate with the GH via a network link created between the at least one GN and the GH. The GNs join the LPG via the GH. If there is more then one GH in an LPG, header resolution occurs to select only one GH.

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.
