MAC Protocol of Standard ECMA-368
The protocol of MAC sub-layer of Standard ECMA-368(2nd Edition) is specified in this paper.The main idea of the sub-layer functionality is studied and analyzed.Our analysis covers the format of frames and information elements,the structure of superframe,the beacon setting and processing,prioritized contention access,distributed reservation protocol,and power management.As a distributed protocol,the MAC policies specified in ECMA standard are desirable for high rate and zero-infrastructure communications among WPAN devices.Also,some flaws of the protocol are discussed in the end.
