Abstract: 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. -
