摘要： The present invention offers systems and methods for effective multiple-hop routing, multicasting and media access control for vehicle group communications that employ directional wireless radio technology. Multi-beam optic-wireless media and streamlined operations provide low-overhead communications among vehicles. Systems and methods are provided to maintain a quasi-stationary group of neighboring vehicles, enable high-throughput on-demand switching among multiple vehicles, enable group coding in the vehicle group to achieve higher throughput, and enable dynamic adjustment of link to maintain desirable vehicle group. The proposed solution builds upon the conception of a MAC-free wireless operation and quasi-stationary vehicular switched network to achieve ultra-low-overhead and high-throughput vehicle communications.

摘要： A method for maintaining a local peer group (LPG) for supporting communications among vehicles. The LPG is formed from a plurality of vehicles. Each vehicle is equipped with a wireless communications device. One of the vehicles is selected as a group header node (GH). The method comprises receiving periodically a heartbeat packet from the GH, the heartbeat packet including a maximum hop count, and a heartbeat cycle, forwarding the heartbeat packet until the maximum hop count is reached after waiting for a first random relay delay, which is less than a maximum allowable adjustable value, replying to the heartbeat packet with a membership report packet, forwarding a membership report packet towards the GH, and adding a vehicle that submitted the membership report packet to a LPG membership as a member node of the LPG if the membership report packet is new or updating information for a member node.

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 and system for determining a size of a local peer group (LPG) network in a dynamic roadway (mobile) environment is provided. In one embodiment, the method comprises measuring a roundtrip time between a first node and a second node, and utilizing the measured roundtrip time to select the size of the local peer group network from a lookup table. In another embodiment, the method comprises determining when the roundtrip time exceeds a time interval of the heartbeat signal, and when the roundtrip time exceeds the time interval of the heartbeat signal adjusting the size of the local peer group network.
