Why Data Transmissionon Protocs Matter in Artificial Pancreas Systems

An artificial chapales system is a cyber-physical system where thee state of thee pacient (blood glucose level) must be communicate to a controller multiple times per minute. The controller computs thee necessary insulilin dose and sends commands back to the pump. Any failure in this communicatoon loop - whether due to dropped packets, excessive delay, or security breach - can lead tlo dangeroues hypercoycemia or hypoglycemica.

Data transmissionon protocors definite the rule for packaging, adressing, transminting, and receiving these messages. They mutt offfer:
