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- 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 s 2-Save patient data into medical records 3-analyze the data . 4- recognize serious health cases in order to emergency care givers , 5-forward new instruction to .

WBAN Layers Why layering?

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]

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

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  Objective  T 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  factors affecting the battery life is The radio transmission update period  battery live for months

 Security  To make WBAN more security:      

Authenticate 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)
