1. 788.11J Presentation Wearable Wireless Body Area Networks (WWBAN) Presented by Jingjing He

2. Motivation Statistics suggest that health care needs a major shift toward more scalable and more affordable solutions. Wearable systems for continuous health monitoring are a key technology in helping the transition to more proactive and affordable healthcare

3. The Main Idea Seamlessly integrate sensor nodes into wireless personal or body networks (WPANs or WBANs) for inexpensive, non-invasive, continuous, ambulatory health monitoring with almost real- time updates of medical records via Internet.

4. The Main Achievements prototype sensor network for health monitoring, including system architecture, hardware and software organization solutions for time synchronization, power management and on-chip signal processing

5. The Challenges synchronized time stamps for proper correlation of data coming from different sensors and for efficient sharing of communication channel reduced total power consumption: wearable sensors means size of sensor small enough, so does the battery size

6. WWBAN Architecture

7. Hardware Multiple ActiS sensor nodes; Each sensor node utilizes a commercially available wireless sensor platform Telos and a custom intelligent signal processing daughter card attached to the Telos platform

8. Innovation The idea to use WWBAN to enable continual, unobtrusive, ambulatory heath monitoring itself is cool In this paper, authors gave a prototype WWBAN based on off-the-shelf wireless sensor platforms and custom-designed ECG and motion sensors, which makes the idea more exciting.
