Abstract: Sensor data characterizing an event associated with a movable object is received. Based on the sensor data, an objective from a plurality of predefined objectives for monitoring the movable object is selected. A series of operational states having increasing power requirement levels is transitioned through. At each operational state, whether the selected objective is achievable using a respective method associated with the respective operational state and respective power requirement level is determined. Related apparatus, systems, techniques and articles are also described.
