WBAN: Motivation
Goal: ubiquitous and affordable healthcare Conditions: demographic and technology
trends Solution: 3-tier ubiquitous monitoring system
– Tier 1: Wireless Body Area Network (WBAN)– Tier 2: Personal Server– Tier 3: Healthcare Provider Servers
Opportunities: – Ambulatory health monitoring– Computer-assisted rehabilitation– Augmented reality systems
Long-term benefits:– Promote healthy lifestyle– Seamless integration of data into personal medical
records and research databases – Knowledge discovery through data mining

Issues in WBAN
Affordable and ubiquitous monitoring – Utilize common off-the-shelf components,
capable of seamless integration into a WBAN Open issues
– Standardization of sensors (specificity, range, precision, type)
– Rules of engagement and sensor placement– Sensor calibration & customization– Integration of data into medical databases– Privacy and security
Social impact and business opportunities
