  1. Wireless Body Area Network (WBAN) EE (400) Presentation Prepare by Wael Ba-deghaish Mohamed Ba-oum For Dr Samir Al-Ghadban

  2. Presentation Outline: 1 Introduction 2 Stander 3 Archatcher 4 OSI Layer 5 WBAN Drawback 6 Conclution

  3. introduction What is WBAN?. What is the benefit of using WBAN( Ali story). Learn How this Tech work Figure 1:data follow into integrate in WBAN system[3]

  4. WBAN Stander • Not yet specified. • WBAN application of WPAN (WSN , Zigbee) 802-15 Figure 2: wireless group stander[2]

  5. Arctiture • Three Tire Figure 3:WBAN architecture[1]

  6. Tire: WBAN Sensor • Consist of intelligent node ( sensing, sampling, processing, and communicating) • Sensor Arcticture Figure 4: Sensor node[3]

  7. Example of WBANs 1 ECG(monitoring heart activity) Figure4: 2 EMG (electromyography) 3 For sensing motion ( activity) figure5: Example of sensor node[3]

  8. Tire2: 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. Tire3-Medical server • Function: 1-to authenticate users 2-Save patient data into medical records 3-analyze the data . 4- recognize serious health cases in order to contact emergency care givers , 5-forward new instruction to user.

  10. WBAN LayersWhy layering?

  11. Physical Layer • Radio Band figure6: Radio Band of WBAN [1] • Modulation • Data Rate table 1:modulation type of WBAN[1] table 2: data rate of WBAN sensor[1]

  12. Data Link Layer • Data Link Layer • Objective • DLL Responsible for Reliable Transfer of Frames from one node to the other (no loss, no corruption, no duplication) • MAC • Control access to the shared medium (radio channel) • Avoid interference between transmissions

  13. Data Link Layer • MAC protocol • (CSMA-CA) • use with wireless LAN • simplicity implementation • lower system cost • reliable data transmission • TDMA( Schedule Protocol) • WWAN like (GSM) Figure 7: CSMA/CA protocol procedure [1]

  14. MAC protocol comparison:table 3: comparison between TDMA and CSMA/CA

  15. Network Layer • Protocol is IP • network topologies within WBAN • Peer-to-peer communication (WLAN) • Ad-Hoc Routing • Infrastructure (WWAN) • Access point (AP) or base station (BS) • Figure7: Two different network topologies are depicted: (a) ad hoc mode and (b) infrastructure mode [3].

  16. Transport Layer • Objective • TCP protocol • Reliable (because relate with human health) • Acknowledgment Application Layer • Data from sensor send as email • Use Simple Mail Transfer Protocol (SMTP)

  17. Summary WBAN Layers

  18. Drawback WBAN • Battery Life • factors affecting the battery life is The radio transmission update period • battery live for months • Security • To make WBAN more security: • Authenticate figure 8: Battery live for WSN [2] • Verify • Encrypt • Key Management • FHSS • Figure9: FHSS protocol [2]

  19. Conclusion : • WBAN serve patient and Doctor • Improve WBAN to avoided security and interference problem • In future may Build new stander WBAN • In future improve WBAN to use with 4G (WI-MAX)
