  • PRESENTERDEEPAK CHANDRA PANT ECE (4th Yr.) 10/27/2013 1
  • Outline1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Introduction of BAN What is BAN…??? History and Development Architecture of BAN Taxonomy and Requirements Positioning of WBAN Patient Monitoring through BAN Applications Challenges Future Scope Conclusion 10/27/2013 2
  • Introduction  Increasing population and the rising costs of health care have triggered the introduction of novel technology-driven enhancements to current health care practices.  Recent advances in electronics have enabled the development of small and intelligent (bio-) medical sensors which can be worn on or implanted in the human body.  Thus introduced Wireless Body Area Network (WBAN). 10/27/2013 3
  • What is BAN…???  Definition by IEEE: “A communication standard optimized for low power devices for their operation on, in or around the human body (but not limited to humans) to serve a variety of applications including medical, consumer electronics or personal entertainment and other.”  Broad range of possible devices  Connect everything you carry on you and with you  Offer “Connected User” experience 10/27/2013 4

  • History and Development of BAN  BAN technology is still an emerging technology. 1 Gbit/s Wireless USB 100 Mbit/s 10 Mbit/s IEEE 802.11 a/b/g 1 Mbit/s 100 kbit/s Bluetooth ZigBee 10 kbit/s 1 kbit/s 500 mW 1000 mW 2 mW 5 mW 10 mW 20 mW 50 mW100 mW200 mW 10/27/2013 6
  • BAN Draft Specifications  Distance  Network density  Network Size  Net network throughput  Power consumption 2 m std, 5 m special 2 - 4 nets / m2 max. 100 device/network 100 Mbit/s max. ~ 1mW / Mbps (@ 1 m distance)  Startup time  Latency (end to end)  Network setup time < 100 us, or < 10% of TX slot 10 ms < 1 sec (after initial setup, per device) 10/27/2013 7
  • Contd…  Implementation module cost  Should be comparable to Bluetooth module  Effective sleep mode(s)  Operates in global, license-exempt band  Peer to peer communication, point to multi-point  Omni-directional antennas: small, flexible  Future proof [for 5 years?]  Upgradeable, saleable, backwards compatibility 10/27/2013 8

  • Positioning of WBAN  The communication in WBAN is divided into: Intra-body Communication 2. Extra-body Communication 1. Figure: Intra-body and Extra-body Communication in WBAN 10/27/2013 11
  • Patient Monitoring through BAN A BAN allows continuous physiological parameters. 10/27/2013 monitoring Figure: Patient Monitoring in a WBAN of the 12
  • Applications of BAN WBAN applications are divided into 3 categories as- Figure: WBAN Applications 10/27/2013 13
  • 1. Health Care  Current healthcare applications of wireless sensor networks target heart problems cancer, asthma, glucose level monitoring, stress monitoring etc.  Smart biosensors will open up new opportunities for continuous monitoring of patients. 10/27/2013 14
  • 2. Assisted Living Figure: WBAN as Assisted Living 10/27/2013 15
  • 3. Entertainment and Sports Figure: WBAN in Entertainment, Fitness and Sport 10/27/2013 16
  • Challenges 1. • • • • • Hardware-centric Challenges Interoperability System Devices System and Device-level Security Data Consistency Interference 2. • • • Human-centric Challenges Cost Constant Monitoring Consistent Performance 10/27/2013 17
  • Advantages of BAN  Used for detection of chronic diseases.  Used in military for security purposes.  Assists seamless communication between individual and peoples. 10/27/2013 18
  • Future Scope  The future market of WBAN is growing rapidly in the field of medical as well as in the entertainment industry.  We believe that WBAN systems will allow a dramatic shift in the way people think about and manage their health.  This provide more proactive preventive healthcare that will not only improve the quality of life, but will also reduce healthcare costs. 10/27/2013 19
  • Conclusion  A WBAN is expected to be a very useful technology with potential to offer a wide range of benefits to patients, medical personnel and society through continuous monitoring and early detection of possible problems.  The current technological evolutions will bring us closer to a fully operational WBAN that acts as an enabler for improving the Quality of Life. 10/27/2013 20
