1. A system to manage inter-vehicle communication in a decentralized vehicle-to-vehicle network, comprising:

  • a plurality of sensors to detect context information about driving conditions proximate a first vehicle;

    a communication interface to manage communications between the first vehicle and a second vehicle; and

    a controller communicatively coupled to the plurality of sensors and the communication interface and comprising processing circuitry, to;

    receive context information from the plurality of sensors;

    determine, from the context information, when the first vehicle is approaching a dead zone in which contact with a communication network may be lost; and

    in response to a determination that the first vehicle is approaching a dead zone in which contact with a communication network may be lost, to activate a synchronization frame broadcast module to broadcast a synchronization frame via the communication interface, wherein synchronization frame comprises;

    a synchronization frame header;

    a time stamp;

    a standard deviation of the time stamp with respect to a standard time reference;

    a location coordinate; and

    a synchronization frame transmission end time.
