1. A method comprising:
transmitting energy, by a reflected energy device, onto an aggregated node group, wherein the aggregated node group includes a plurality of device nodes respectively physically integrated with a plurality of assets, wherein the aggregated node group is moveable from one location to another, and wherein the assets are physically clustered within the aggregated node group such that the assets move together as the a ted node group is moved;
sensing, by the reflected energy device, the energy transmitted by the reflected energy device as has been reflected by the aggregated node group or the nodes thereof, to detect a state change event associated with the aggregated node group, wherein when the energy is reflected, the nodes are in a lower power state in which the nodes are in standby or sleep and do not communicate; and
upon detection of the state change event, transmitting to the aggregated node group, a first change state instruction signal that directs at least one node of the aggregated node group to transition from the lower power state to a higher power state in which the at least one node is awake and communicates.
