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.

Abstract
A collaborative method for a node includes forming a local network with at least one other node using a lower power subsystem; selecting a master node from among the local network based on a first set of criteria; and communicating with a back end server over a wireless wide area network (WWAN) using a higher power subsystem. An apparatus may include a first subsystem for communicating with a local network; and a second subsystem having an active mode and an inactive mode, the second subsystem for communicating with a wireless wide area network (WWAN) when in the active mode, the apparatus selecting the active mode or inactive mode based on a set of criteria.

36. 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 first set of criteria and the second set of criteria includes remaining battery life of each of the nodes and a WWAN condition with respect to each of the nodes for each of the nodes.

37. 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 (i) a transition cost of changing a power state of one or more of the first master node and a second master node and (ii) a second set of criteria; and deactivating, in response to the deselecting 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.
