4. The following MAC Enhancements are added in CWPAN
Nov. 2007
The following MAC Enhancements are added in CWPAN
Propose a Non-persistent CSMA/CA to provide an enhanced CAP performance with lower complexity
Propose a Distributed Contention Access Scheme to increase the throughput
Propose a GTS extended to use the inactive period in superframe for energy-unlimited devices
Propose a shared GTS scheme to increase the efficiency of usage, while the GTS requirement frame format is expanded
Propose a enhanced security scheme on the MAC layer to provide device authentication

5. The Cooperation of CWPAN and IEEE802.15.4e
Nov. 2007
The Cooperation of CWPAN and IEEE e
CWPAN would cooperate with 4E in the same way as 4C.
Invite the members of 4E to attend CWPAN.
Attend on-site and Phone meeting as scheduled.
Presently, Paul Dixon, Pei Liu and Liang Li would be in charge this cooperation.
