ObjectiveThe objective of this paper is to describe and evaluate an algorithm to reduce power usage and increase battery lifetime for wearable health-monitoring devices.MethodsWe describe a novel dynamic computation offloading scheme for real-time wearable health monitoring devices that adjusts the partitioning of data processing between the wearable device and mobile application as a function of desired classification accuracy.ResultsBy making the correct offloading decision based on current system parameters, we show that we are able to reduce system power by as much as 20%.ConclusionWe demonstrate that computation offloading can be applied to real-time monitoring systems, and yields significant power savings.SignificanceMaking correct offloading decisions for health monitoring devices can extend battery life and improve adherence.
