S-supported MAC • IEEE 802. 15. 4 - 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 Slide 4 Sung.

May 2008 Doc: IEEE 802. 15 -08 -0000 -00 -0 ban MAC protocols for WPAN (2/3) • TDMA-based MAC − Pros: • Low power use ü Nodes only listen at start of time slot ü Nodes only send on own time slot ü Once local group is arranged, No control packets − Cons • Requires some form of time synchronization • Scales badly: bluetooth limit is 8 • Low bandwidth utilization Slide 5 Sung.

May 2008 Doc: IEEE 802. 15 -08 -0000 -00 -0 ban MAC protocols for WPAN (3/3) • Contention-based MAC − Pros ü Avoid collisions well ü High scalability − Cons ü High cost from control overhead ü High power consumption in idle mode ü Doesn’t work for multicast • WSN-specific MAC: coordination of existing MAC protocols − Pros ü Energy efficiency of TDMA, Collision avoidance of IEEE 802. 11 ü Low latency than TDMA − Cons ü Application-specific MAC, So dependent on PHY Slide 6 Sung.
