  4. 4. Wireless Body Area Network (WBAN): To wards a wearable intranets…. WBN26/07/2013 Taken from: Introduction
  5. 5. BAN: 5  An interdisciplinary area which allows inexpensive and continuous health monitoring with real-time updates of medical records through the Internet.  In these networks various sensors are attached on clothing or on the body or even implanted under the skin.  The sensors of a WBAN measure e.g. the heartbeat, the body temperature, the glucose level etc  IEEE 802.15.6 is a new standard for Body area networks
  6. 6. 6 ARCHITECTURE
  7. 7. 7 What BAN contains ? • Bio-Sensors: It is used to measure the vital signs on the human body • Transceivers : Devices transmits and receives data • Processors : analyzes the data and manages the system • Battery: Supplies power
  8. 8. WBN 8 Health care monitoring system
  9. 9. 9 very small biosensors are implanted inside the human body that are comfortable and that don't impair normal activities.  These sensors collect various physiological changes in order to monitor the patient's health status no matter their location.  information will be transmitted wirelessly to an external processing unit and then instantly transmit all information in real time to the doctors If an emergency is detected, the physicians will immediately inform the patient through the computer system by sending appropriate messages or alarms
  10. 10. WSN 10
  11. 11. Various Types of Sensors: ECG: for monitoring heart activity EMG: for monitoring muscle activity EEG: for monitoring brain electrical activity SPO2:a breathing sensor for monitoring respiration blood pressure sensor  a tilt sensor for monitoring trunk position movement sensors used to estimate user's activity
  12. 12. Physiological sensors, such as ECG and SpO2 have been developed. Sensors such as blood pressure sensor, EEG sensor are under development
  13. 13. Specific requirements: 1. Ultra low power consumption: This constraint exists to allow sensors to have the smallest batteries 2. Suitable sensors: Sensors should be small; they must not hinder users’ life. 3. Lifetime: Sensors must have a long lifetime, particularly
  14. 14. Network requirements: 1. Range: BAN allow the sensors in on or around the same body to communicate with each other, so 2-5 meters range is enough 2. Interference: interference among the sensors should be suppressed as much as possible to satisfy reliable wireless communication. 3. Network density: BAN standard allows 2-4 networks per m2 . 4. Sensors number per network: BAN standardization group expects a maximum of 256 devices per network 5. Security/encryption: The transmitted data needs to be protected WSN 14
  15. 15. Applications: Health care Assisted living Sports and Exercises Entertainment
  16. 16. BENEFITS • Promote healthy life style • Beneficial for patients suffering from chronic diseases such as diabetes , asthma and heart attacks. e.g. If high sugar level detected, a device triggers an insulin pump to inject a dose of insulin • Alerting the patient via SMS, alarm or reminder messages • Reduction in hospital stays • Regulation of treatment regimes WBN 16
  17. 17. Limitations: unwieldy wires between sensors and a processing unit lack of system integration of individual sensors interference on a wireless communication channel shared by multiple devices Security and Privacy challenge.
  18. 18. CONCLUSION The WBAN is an emerging and promising technology that will change people’s healthcare experiences revolutionarily. Data security and privacy in WBANs and WBAN-related e-healthcare systems is an important area, and there still remain a number of considerable challenges to overcome
