1. A collaborative method for a first node, the method comprising:

  • connecting the first node in a local network with at least one other node using a low power subsystem of the first node;

    enabling the first node as a first master node from among the local network based on a first set of criteria;

    activating, in response to the enabling, a high power subsystem of the first master node for communicating over a wireless wide area network (WWAN);

    communicating with a back end server over the WWAN using the high power subsystem of the first node;

    disabling the first node as the first master node based on a second set of criteria; and

    deactivating, in response to the disabling, the high power subsystem of the first node while maintaining operation of the low power subsystem of the first node;

    wherein a second master node may be selected from the local network for communicating with the back end server;

    wherein the second set of criteria includes at least one of (i) a WWAN condition and (ii) a transition cost of changing a power state of the high power subsystem.
