This presentation outlines a wireless body area network (WBAN) system for remote patient monitoring. It discusses the key components of a WBAN including sensors, personal servers, and medical servers. WBANs use low-power wireless sensors to monitor things like heart activity and motion. Data from the sensors travels through a personal server like a phone and on to a medical server for storage, analysis, and emergency alerts. The presentation covers WBAN standards not being specified yet, the typical three-tier architecture of sensors, personal servers, and medical servers, and challenges around limited battery life and security issues that need addressed.

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 Layers
Why 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)
