1. A first mobile device comprising:

  • a wireless transmitter included in the first mobile device, the wireless transmitter enabling the first mobile device to establish a direct communication over a network infrastructure; and

    a communication system in the first mobile device, the communication system configured to;

    establish, via the wireless transmitter, communication over a wireless ad hoc network with a second mobile device, wherein the wireless ad hoc network is separate from the network infrastructure;

    facilitate receiving an uplink message from the second mobile device over the wireless ad hoc network, the uplink message being directed to intended for a node within the network infrastructure;

    store the uplink message in a memory buffer when the direct communication over the network infrastructure is unavailable to the first mobile device;

    facilitate forwarding the uplink message to the node using the network infrastructure at a time after the direct communication over the network infrastructure is available to the first mobile device;

    facilitate receiving a downlink message from the node over the network infrastructure, the downlink message being intended for the second mobile device, wherein the second mobile device is not in direct communication with the network infrastructure; and

    calculate a pattern of access for a communication link with the second mobile device over the wireless ad hoc network, wherein the communication system is further configured to either;

    store the downlink message in the memory buffer when the communication link is unavailable with the second mobile device over the wireless ad hoc network and predicted to become available at a particular point in time based at least in part on the calculated pattern of access for the communication link with the second mobile device; and

    facilitate forwarding the downlink message to the second mobile device over the communication link with the second mobile device at the particular point in time in which the communication link was predicted to be available using the wireless ad hoc network;

    orfacilitate discarding the downlink message intended for the second mobile device when the communication link is not predicted to become available based at least in part on the calculated pattern of access for the communication link with the second mobile device.
