Communication Challenges in a Multi-Sensor Closed-Loop Artificial Pancreas System

Abstract

This paper describes the communication challenges associated with implementation of a multi-sensor artificial pancreas system on a smartphone device and presents solutions for potential communication losses. In particular, a standardized development framework on an Android device supporting multiple sensors is introduced in order to facilitate a multi-variable closed-loop AP algorithm. Package losses and communication link errors pose major challenges for the AP systems to overcome. The proposed solution offers a conservative model, wherein the controller application on the host smartphone requests status updates, resending of packages if necessary, and ultimately, warnings are issued to the user when data cannot be recovered.
