摘要： 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.
