A system for detecting sensor position change (DCPC) on movable vehicle components includes two or more sensors on at least one of the movable vehicle components. The sensors detect optical information within a distinct field of view (FOV) about an environment surrounding the vehicle. The distinct FOV of each sensor at least partially overlaps with an FOV of at least one other sensor. The system includes controllers that execute an application for DCPC. The DCPC application acquires overlapping optical information from the sensors, computes a conditional correspondence probability distribution for feature points in the overlapping optical information, computes a normalized joint entropy of the feature points, determines that the sensor is in a position manageable by the DCPC, continuously monitors positions of each of the sensors, selectively dynamically aligns the sensors, and ensures that the sensors are calibrated for vehicle perception tasks including advanced driver assistance system (ADAS) functions.

Network congestion occurs when the volume of data to be sent from one node to another, in a given time, exceeds the network's capacity. While all networks are susceptible to congestion, a wireless network of vehicles / moving vehicles are particularly sensitive as any delays in offloading acquired data may cause the vehicles / moving vehicles to pause operations (e.g., hover or land and later return to a location) while waiting to send data. By monitoring data buffer size and / or other system attributes, a measure of how successful data transmission is a corresponding degree of network congestion. When network congestion is present congestion mitigating actions are taken.
