2. Medium Access Control (MAC) requirements for BAN
SungHyup Lee and YangMoon Yoon KORPA (Korea Radio Promotion Agency)
I am SungHyup Lee from South Korea and work for KORPA
The title of my talk is “Medium Access Control (MAC) requirements for BAN.

3. Purpose and Contents
This document presents the MAC requirements for BAN
Contents
Goal of MAC protocol for BAN
MAC issues on BAN
MAC protocols for WPAN
Intra / Inter body communications
Considerations of MAC protocol for BAN 3

4. Goal: Outline of MAC requirements for BAN
The MAC (Medium Access Control) Layer of the Wireless Body Area Network (WBAN) Standard will be compatible with the IEEE 802 requirements for architecture, management, and inter-networking.
Energy-efficient wireless body area network
- Battery-powered devices
Body sensor: recharge/exchange (alternative)
Wearable devices: recharge/exchange (possible)
Harmonization and convergence with the different MAC technologies for near-field communication
- Scalable MAC protocol
The goal of this draft is to indicate the outline of MAC requirements for BAN.

8. Inter/Intra body communications
Intra-body communication (BAN-BAN)
Personal server to personal server communication paradigm
WPAN-centric technology
IEEE (WPAN)
Bluetooth SIG (Special Interest Group)
Inter-body communication (BAN-External network)
Personal server to AP/BS communication paradigm
should use internet to communicate with control center and end user
IEEE (WLAN)
IEEE (Wired network) 8

9. Consideration of MAC protocols for BAN
Scalable and flexible protocol
BAN can consist of the variety wireless devices
Application-dependant protocol
Medical and non-medical applications
Heterogeneous devices
Sensors / Wearable devices
Inter-networking and inter-operation with Internet or external network. 9

10. Consideration of MAC protocols for BAN
Questions for deployment
How to control and manage the different MAC protocols?
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
In this slide, we consider the following questions?
How to solve and overcome?
Optimized
approach 10
