摘　　要：为了更好地实现无线办公室组网、无线家庭组网,必须对UWB无线网络的QoS进行优化。对UWB无线网络MAC协议——IEEE 802.15.3进行了分析,介绍了基于跨层设计的DCC-MAC算法。在NS2.29环境下进行了仿真,测试表明:即使节点数增多,干扰增强,采用DCC-MAC协议的UWB无线网络能保持比较高的平均吞吐量,当节点的总个数从2到60变化时,系统吞吐量约为250Mbit/s。To realize better wireless local area network in the office and the family, the quality of service（QoS） for ultra wideband（UWB） wireless network must be improved. The medium access control （MAC） protocol（IEEE 802. 15. 3 ） of UWB wireless network is analyzed. The algorithm of dynamic channel code（DCC-MAC） based on cross-layer is presented. It has been simulated on NS2.29, and the experiment results show that the capacity of UWB wireless network increased is bigger using DCC-MAC algorithm even if the node＇ s number is added to and the interference is enlarged. The capacity of UWBwireless network is about 250 Mbps when there are 2 to 60 nodes in the network.
