摘要
媒体接入控制技术的核心问题是如何协调多个用户共用一个信道实现高效可靠传输,即多址接入问题。文章在介绍常用MAC层协议的基础上,针对移动终端的发射功率各异、传输半径不同的情况,进行了非对等网络MAC层协议分析,剖析了协议应用于基于UWB技术的Adhoc网络时存在的隐式终端、显式终端问题,并给出了相应的解决问题的方法。
The medium access control Technology focuses on multi-address access, that is, how to coordinate users sharing a common channel to achieve efficient and reliable transmission. In view of the situation that diversified mobile terminals have different transmission powers and radii, the paper analyzes two kinds of advanced MAC protocols and goes deeply into the problems of hidden terminals and exposed terminals when the protocols are applied on the UWB-based Ad hoc network. Finally relevant solutions are provided.
