Space Reuse Based Media Access Control Technique for Ultra-wideband Systems

该文研究超宽带无线网络的媒体接入控制技术和协议。主要分析有望适配应用在未来超宽带网络中的 IEEE 802．15.3的媒体接入控制协议的基本原理,应用超宽带通信具有精确定位信息的特征,改进IEEE 802．15.3协议。提出一种基于空间复用的超宽带媒体接入控制方案。仿真结果表明,与基本IEEE 802．15．3技术相比,空间复用媒体接入控制技术的网络吞吐量和数据包接入时延性能都得到了较大的改善。

This paper studies the media access control protocol and key technologies in ultra-wideband wireless networks. It is mainly analyzed that the basic principle of IEEE 802.15.3 media access control protocol which is as one of the most suitable protocols for ultra-wideband networks. Using the character of accurate location information of ultra-wideband communication, the IEEE 802.15.3 protocol is improved and a scheme which is media access control technique based space reuse is proposed. Simulation results reveal this new proposal improves the performance of network throughput and packet access delay compared with basic IEEE 802.15.3 media access control scheme,
