摘要
本文针对ECMA-368标准第二版的媒体访问控制(MAC)协议,在介绍帧格式、超帧结构的基础上,分析总结了MAC子层的信标机制、PCA协议、DRP协议和能量管理等主要内容。作为一种全分布式的MAC协议标准,ECMA-368可以有效地管理和控制设备,为上层提供灵活的数据通信服务,非常适合无中心的高速无线个域网络。文章最后也指出了协议在具体应用方面的若干不足。
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.
