Abstract
Wireless body area networks WBANs and their supporting information infrastructures offer unprecedented opportunities to monitor state of health without constraining the activities of a wearer These mobile point of care systems are now realizable due to the convergence of technologies such as low power wireless communication standards plug and play device buses off the shelf development kits for low power microcontrollers handheld computers electronic medical records and the Internet To increase acceptance of personal monitoring technology while lowering equipment cost advances must be made in interoperability at both the system and device levels and security This paper presents an overview of WBAN infrastructure work in these areas currently underway in the Medical Component Design Laboratory at Kansas State University KSU and at the University of Alabama in Huntsville UAH KSU efforts include the development of wearable health status monitoring systems that utilize ISO IEEE 11073 Bluetooth Health Level 7 and OpenEMed WBAN efforts at UAH include the development of wearable activity and health monitors that incorporate ZigBee compliant wireless sensor platforms with hardware level encryption and the TinyOS development environment WBAN infrastructures are complex requiring many functional support elements To realize these infrastructures through collaborative efforts organizations such as KSU and UAH must define and utilize standard interfaces nomenclature and security approaches
