4. MAC protocols for WPAN (1/3)
IEEE
Polling-based MAC
IEEE
TDMA-based, Contention-based, QoS-supported MAC
IEEE
Contention-based MAC
WSN-specific MAC
All MAC protocols can be used for the BAN
We need to extend and improve the existing MAC technologies 4

5. MAC protocols for WPAN (2/3)
TDMA-based MAC
Pros:
Low power use
Nodes only listen at start of time slot
Nodes only send on own time slot
Once local group is arranged, No control packets
Cons
Requires some form of time synchronization
Scales badly: bluetooth limit is 8
Low bandwidth utilization 5

6. MAC protocols for WPAN (3/3)
Contention-based MAC
Pros
Avoid collisions well
High scalability
Cons
High cost from control overhead
High power consumption in idle mode
Doesn’t work for multicast
WSN-specific MAC: coordination of existing MAC protocols
Energy efficiency of TDMA, Collision avoidance of IEEE
Low latency than TDMA
Application-specific MAC, So dependent on PHY 6

9. MAC considerations for Non-Medical Application
MAC technology
Enhanced MAC
Different frequency
Convergence
Bluetooth
Human Safety
Adaptation
ZigBee
Reliability
Harmonization
UWB
Link connectivity
Security
NFC
Different PHY
Each one of exiting MAC Protocols is not enough and a unified MAC
Protocol is not easily made, either.
Each MAC should guarantee coexistence with each other 9

10. MAC considerations for Non-Medical Application
Case 1: If all devices use the different MAC technologies,
they should have the same size and length of MAC frame.
Peer-to-Peer : only synchronization
Multi-Peer-to-Server : to enhance the process time and load
to improve the flexibility and compatibility
Bluetooth-based headset
UWB-based Pocket PC
ZigBee-based handheld
Human server
UWB-based Game machine
ZigBee-based fitness
Bluetooth-based mp3 10
