Abstract

A scalable telemonitoring system for secure long-term monitoring of signals in life-science applications is presented that enables unobtrusive remote patient monitoring with small and lightweight general-purpose sensor nodes. Sensor data are sent to a retail smartphone via the ultra-low-energy wireless ANT protocol and forwarded over 2G, 3G or Wi-Fi to the cloud-based IPM-mHealth Portal that provides services for administration, communication, live visualization and data analysis. Additional protocols improve reliability and flexibility of the ANT interface and all wireless transmissions are encrypted by either SSL or the computationally lightweight Hummingbird 2 (HB2) cipher. On-sensor data compression is applied to minimize communication energy. Experimental data show performance and energy balance of the ANT-based sensor interface and quantify the HB2 encryption overhead.
