Low resource demanding FOTA method for remote AtoN site equipment

This paper presents a method for firmware update in memory constrained low-power controllers used in marine aids to navigation (AtoN) and telematics systems. The developed method allows carrying out firmware updates regardless of the communication channel used. This approach differs from other similar methods mainly by its low requirements to hardware and high flexibility; hence it is applicable to relatively small microcontrollers. The paper is concluded with experimental results performed on operational marine buoys.
