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