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)
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 Layers Why layering?

11. 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]

12. 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

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

17. Summary WBAN Layers

18. 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]

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)
