This document discusses wireless body area networks (WBANs), which allow for inexpensive and continuous health monitoring through connecting various medical sensors and appliances located inside and outside the human body via wireless communication. WBANs have a three-tier architecture, consisting of intelligent sensor nodes on the body (Tier 1), a personal server like a cell phone (Tier 2) that interfaces with the sensors, and a medical server (Tier 3) that authenticates users, stores patient data, analyzes sensor data, and can alert emergency services if needed. WBANs allow remote monitoring of patients with chronic conditions and can alert hospitals to health issues even before symptoms occur.
Wireless body area network
- 1. Wireless Body Area Network Name : Pratik Gondaliya Roll No : 17
- 2. What is WBAN ? • wireless body area network (WBAN) is a wireless network of wearable computing devices. • The body area network field is allow inexpensive and continuous health monitoring with real-time updates of medical records through the Internet. 2
- 3. • WBAN is a special purpose sensor network designed to operate autonomously to connect various medical sensors and appliances , located inside and outside of a human body. 3
- 4. Positioning WBANS • The protocols developed for WBANs can span from communication between the sensors on the body to communication from a body node to a data center connected to the internet. • Thus communication in WBAN is divided into two parts : –Intra body communication –Extra body communication 4
- 5. • Intra body communication controls the information handling on the body between the sensors and personal device. • Extra body communication ensures communication between the personal devices and an external network . 5
- 6. Comparison with another Network 6 • A WBAN is operated close to human body and its communication range will be restricted to a few meters, with typical values around 1-2 meters.
- 8. Tier 1 WBAN • Consist of intelligent node (Sensing , Sampling , Processing). 8
- 9. Tier 2:Personal server • Interface the WBAN sensor nodes through Zigbee or Bluetooth. • Connected with the medical server through mobile telephone networks (2G , GPRS, 3G) or WLANs-Internet. • Implemented regularly at cell phone. Functions 1.Register type and number sensor node. 2. Manages the network channel sharing, time synchronization , and processing data. 3. Send data to MS. 9
- 10. Tier 3 : Medical Server • Function – To authenticate users. – Save patient details in medical server – Analyze the data – Recognize serious health cases in order to contact emergency care gives – Forward new instruction to user. 10
- 11. Types of patient can be handle 11 • Patients who is suffering from chronic diseases such as diabetes, asthma and heart attacks. • A WBAN network in place on a patient can alert the hospital, even before they have a heart attack, through measuring changes in their vital signs. • A WBAN network on a diabetic patient could auto inject insulin through a pump, as soon as their insulin level declines.

- 14. Advantages • doctors can follow vital signs of their patients at the same time and can be alerted if one of them has got a problem. • Emergency services can be get from the doctor. • Patient has not required to physical available to the doctor. 14
- 15. Disadvantage • Battery Life – Factor affecting for battery life is the radio transmission update periodically Security –Authenticate –Verify –Encryption 15
