3. Non-medical BAN Traffic
Type of service
Type of traffic
Description
Real-time service
Constant Bit Rate Traffic
Interactive Voice, Video and Gaming
Stringent QoS
Real-time Variable Bit Rate Traffic
Compressed Audio and Video Streams
Transmission in burst
Less stringent QoS than CBR
Non-real-time service
Unspecified Bit Rate traffic
File or text data transfer
Similar to non-real-time VBR
Best effort service, enjoyed success in LAN

4. MAC protocol should:
Distinguish and prioritize the traffic based on its real-time requirements
- Need of coordinator
- Coordinator should have control over the order of transmission
Have low-latency characteristics to support real-time behavior
- Fixed bandwidth may required for CBR traffic
Have contention based access for VBR traffic
- Contention between real-time VBR and non-real-time VBR may degrade
the performance of real-time VBR
- First packet of real-time VBR may contend, have mechanism to reserve channel
for other VBR packet in a flow
Distinguish and treat differently packets in a real-time VBR flow
Maximize utilization of the medium
- No idle channel
Energy consumption is critical for BAN nodes used for motion/posture detection
