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.
