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

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

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]

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

Arctiture Three Tire Figure 3:WBAN architecture[1]

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

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

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

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.

WBAN Layers Why layering?

Physical Layer table 2: data rate of WBAN sensor[1] Modulation 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]

Data Link Layer Data Link Layer MAC 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

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]

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

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].  

Transport Layer Application 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)

Summary WBAN Layers

Drawback WBAN Battery Life Security 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]

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)
