1. A communication device comprising:

  • a first transceiver for transmitting a communication initiation message using low power transmissions to initiate communication with a second communication device in an ad hoc network;

    a second transceiver for transmitting data packets to the second communication device subsequent to initiating communications using the low power transmissions;

    a communications control processor in communication with the first transceiver and the second transceiver;

    configured for;

    receiving scheduling data from the second communication device sufficient to predict a time at which the second communication device will be accepting data communications;

    predicting the time at which the second communication device will be accepting data communications based at least in part on a dynamic threshold;

    causing the first transceiver to power up and transmit the communication initiation message to the second communication device at the predicted time;

    causing the second transceiver to power up and transmit at least one of the data packets to the second communication device subsequent to transmitting the communication initiation message;

    receiving, by the communication device, updated scheduling information including an updated dynamic threshold, indicating a changed availability of the second communication device.
