    Abstract: A technology is described for a wireless sensor network. An example method may include detecting an aircraft takeoff preparation event using cabin air pressure data and accelerometer data indicating that an aircraft is preparing for takeoff. Transmitting a listen command to sensor nodes included in a sensor network, the listen command instructing the sensor nodes to disable the wireless network transmissions and listen for commands transmitted by the gateway. Disabling gateway wireless transmissions to the sensor nodes and a computing network. Detecting a landing event using the cabin air pressure data and the accelerometer data indicating that the aircraft has landed. Enabling the gateway wireless transmissions to the sensor nodes and the computing network, and transmitting an enable command to the sensor nodes included in the sensor network, the enable command instructing the sensor nodes to enable the wireless network transmissions and resume sending sensor data to the gateway.

    Abstract: Lost, misplaced, incorrectly delivered, and damaged assets are a common occurrence in shipment or asset tracking. Disclosed are various embodiments concerning a battery-less or intermittent battery use environments in which a node uses internal logic (e.g., circuitry and/or software) that, based at least in part on sensor information and stored information regarding the history of the node, may track events that have occurred to the node. The node may be responsive to events and determine whether exceptions have occurred that require attention. For example, detecting damage might cause the node to update an output to indicate the node and associated material, if any, needs to be rerouted to address the exception.
