2. IntroOH-2 CSE 5810Introduction   Chronic diseases are the leading cause of deaths in the U.S. with 7 out of 10 deaths each year. Heart disease, cancer and stroke account for more than 50% of all deaths each year.  In-hospital screening provide a one-time “snapshot” reading.  Advances in technology provided an opportunity to develop Wireless Body Sensor Networks for continuous monitoring.

3. IntroOH-3 CSE 5810 Wireless Body Sensor Networks (WBSN)   It is a network that works around the human body.   The network consists of one or more body sensors used with a central management device.   It can be used not only for medical uses, but also in other fields such as in military or sports.  sensors,transceiver, processors, accelerometers, and batteries  WBSN nodes contain sensors,transceiver, processors, accelerometers, and batteries
