Security and reliability of data transmissions in biotelemetric system

Abstract

Secure and reliable data transmissions are of vial importance in today's biotelemetric systems. Particularity of biotelemetric data puts special requirements on real biotelemetric system regarding data confidentiality, transport channel reliability, transport latency and latency jitter. This article describes some of conclusions acquired in development of real biotelemetric system using off the shelf embedded hardware technology, namely ARM microcontrollers, FRAM memory and dedicated ZigBee chipsets with emphasis on reliability and security of data transfer. Described biotelemetric system is partitioned into logical parts that communicate using custom data protocols. Devices participating in biotelemetric system use Zig- Bee and Ethernet networks as underlying structure for secure and reliable data communication. © 2010 International Federation for Medical and Biological Engineering.
