摘要： A multiple hop communications method among a plurality of moving vehicles. Each moving vehicles has a plurality of unidirectional radio. The method comprises receiving an incoming packet at one of the plurality of unidirectional radios, determining if there is an active link between each of the plurality of unidirectional radios and an unidirectional radio of a neighbor vehicle, relaying the incoming packet to the plurality of unidirectional radios having an active link and transmitting the incoming packet as an outgoing packet from at least one of the plurality of unidirectional radios. If more than one packet is received, the packets can be encoded using group coding before send the packets out as an outgoing packet.

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.
