  • determining, by a first device, a number of discovery messages received during at least one discovery interval;

    synchronizing a subsequent communication according to one of the number of discovery messages received during the at least one discovery interval;

    halting discovery message transmission attempts by the first device during the at least one discovery interval;

    based on the number of discovery messages, determining an estimated number of devices in an ad-hoc network;

    determining an estimated duration of a second discovery interval based on the estimated number of devices in the ad-hoc network wherein the determining the estimated duration comprises multiplying the estimated number of devices by a per device transmit time of each device within the ad-hoc network;

    during the second discovery interval that is subsequent to the at least one discovery interval, transmitting a discovery message indicating the estimated number of devices in the ad-hoc network, the discovery message transmitted during the second discovery interval, wherein the second discovery interval based on the estimated duration, andsetting a duration of the second discovery interval to match the estimated duration.
