Nov. 2007 Proposals for WPAN MAC Enhance the MAC features for high-data rate throughput on networks Optimize the CSMA Improve GTS and Superframe Simply the MAC structure for special applications Liang, Paul Dixon, Pei Liui

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 Liang, Paul Dixon, Pei Liui

The Cooperation of CWPAN and IEEE802.15.4e Nov. 2007 The Cooperation of CWPAN and IEEE802.15.4e 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. Liang, Paul Dixon, Pei Liui
