Why Data Transmissionon Protocos Matter in Artificial Pancreas Systems

An artificial chapales system is a cyber-physical system where thee state of thee patient (blood glucose level) must be communicated to a controller multiple times per minute. The controller computs thee necessary insulin dose and sends commands back to the pump. Any failure in this communication loop - whether due to dropped pactecs, excessive delay, or security breach - can lead tlo dangeroues hyperglycemia or hypoca.
