Thank you very much Mr. Chairman for your kind introduction.
Good afternoon ladies and gentlemen.
Thank you for coming to my presentation.
And I’m delighted to introduce our draft for BAN.

2. Medium Access Control (MAC) requirements for the BAN
SungHyup Lee and YangMoon Yoon KORPA (Korea Radio Promotion Agency)
I have pleasure to introduce myself.
My name is SungHyup Lee,
I’m Senior Engineer at KORPA.
I will talk about “Medium Access Control (MAC) requirements for the BAN.”

3. Purpose and Contents Contents
This document presents MAC requirements for the BAN
Contents
Outline of MAC requirements for the BAN
MAC issues on BAN
Relationship between BAN and WPAN
MAC for WPAN
Intra / Inter body communications
Considerations of MAC protocol for the BAN
This document presents the MAC requirements for the BAN
The contents of my presentation consist of 6 parts.
First, I introduce the outline of MAC protocol for BAN.
Second, I explain MAC issues on BAN.
Third, I mention the relationship between BAN and WPAN
Fourth, I give an overview of MAC for WPAN.
And then, I introduce the Intra / Inter body communications.
Finally, I focus on the consideration of MAC protocol for the BAN. 3

4. Outline of MAC requirements for the BAN
Energy-efficient wireless body area network
- Battery-powered devices
Body sensor: recharge/exchange (alternative)
Wearable devices: recharge/exchange (possible)
Reliable wireless body area network
Medical application-related data is very important
Therefore, It must reach the end point without loss.
Harmonization and convergence with the different MAC technologies for near-field communication
- Adaptive and Scalable MAC protocol Network layer
I’m going to start with an outline of MAC requirements for BAN.
The essential requirement is Energy-Efficiency
Because body sensor and wearable device are Battery-powered devices.
Another requirement is the reliable wireless body area network
For example, Medical application-related data is very important
Therefore, It must reach the end point without loss.
Last requirement is that MAC protocol for the BAN harmonizes and converges
With the different MAC technologies for the near-field communication.
And so we need the adaptive and scalable MAC protocol
Optionally, it can be supported in Network layer.

5. MAC issues on 802.15 BAN Reliable transmission QoS guarantee
Low power consumption
Secure transmission
Reference) DOC: IEEE ban, Jan
In the previous meeting, MAC issues on BAN are presented.
Data transmission in the BAN, It should be guaranteed the reliability
and Security and Battery-powered device should consume the low power.
Everything are very important factors in BAN as well as WPAN. 5

6. Relationship between BAN and WPAN
IEEE : Bluetooth
IEEE : High data rate WPAN
IEEE : Low data rate WPAN

IEEE
802.15
SG BAN
In this slide, I explain the relationship between BAN and WPAN.
First, IEEE 802,15,1 has derived a WPAN standard based on the Bluetooth.
Second, IEEE 802,15,3 based on High data rate technology such as UWB.
Third, IEEE 802,15,4 based on Low data rate technology such as ZigBee.
IEEE SG BAN includes and has relationship with three standards
because it can use for Medical applications as well as non-medical applications such as wearable devices.
Therefore we can present the relationship to this figure. 6

7. MAC protocols for WPAN IEEE 802.15.1 Polling-based MAC IEEE 802.15.3
TDMA-based, contention-based, QoS-supported MAC
IEEE
Contention-based MAC
WSN-specific MAC
S-MAC, T-MAC, TRAMA..
In this slide, I introduce MAC protocols for WPAN.
IEEE uses the Polling-based MAC.
IEEE uses TDMA-based, contention-based, and QoS-supported MAC..
IEEE uses Contention-based MAC and WSN-specific MAC including S-MAC, T-MAC…
All MAC protocols can be used for BAN.
All MAC protocols can be used for the BAN 7

8. Inter/Intra body communications
BAN devices - personal server communication
WPAN-based technology
IEEE /4 (WPAN)
IEEE (Bluetooth)
Inter-body communication (BAN-BAN)
Personal server - personal server communication
WLAN-based technology
IEEE (WLAN)
Interoperation BAN with External network
Personal server - AP/BS communication
should use Internet to communicate with control center and end user
WLAN, Cellular network
In this slide, I want to introduce 2 definitions: Intra-body communication and Inter-body communication.
Intra-body communication means the data delivery
between BAN devices to Personal server using WPAN-based technology.
Inter-body communication means the data delivery
between BAN to BAN, that is to say, Personal server to Personal Server using WLAN-based technology.
Another focus is Interoperation BAN with External network.
This means the communication between Personal server and AP/BS.
This should use Internet to communicate with control center and end user
Using WLAN or Cellular network. 8

9. Consideration of MAC protocol for the BAN (1/2)
is scalable and flexible protocol
BAN can consist of various wireless devices
Heterogeneous devices: body sensors/wearable devices
is application-dependant protocol
Medical application and non-medical application
supports inter-networking and inter-operation with Internet or external network.
In this slide and next slide, I brief you on the consideration of MAC protocol for BAN.
MAC protocol for the BAN is scalable and flexible protocol
Because BAN can consist of various wireless devices such as body sensor and wearable device.
And It is application-dependant protocol: Medical application and Non-medical application.
I supports inter-networking and inter-operation with Internet or External network. 9

10. Consideration of MAC protocol for the BAN (2/2)
Questions for deployment
How to control and manage the different
Application?
How to support the Routing or upper layer?
How to co-operate with PHY or lower layer?
How to support Multi-hop routing?
How to minimize overhead and frame size?
Scalable
approach
Cross-layer
approach
My final topic is on questions for deployment.
How to solve and overcome?
Optimized
approach 10

11. Summary Outline of MAC requirements for the BAN
Intra / Inter body communications
Consideration of MAC requirements for the BAN
In closing, I would like to summarize the follows.
First, I introduced an outline of MAC requirements for the BAN
Second, I explained Intra/Inter body communications.
Finally, I address the consideration of MAC requirements for the BAN. 11
