摘　　要：面向普适健康服务的无线体域传感网要求网络满足高速、低功耗的要求。通过采用超宽带技术,结合普适健康服务业务需求,构建了高速、低功耗的无线体域传感网。该网络能够支持多种传感器同时检测,通过高速物理层接口,做到生理信息的及时传输。实际原型系统测试表明:该原型系统能够支持10个以上节点,在3 m范围内提供100 Mbps的网络速率,并且发送节点平均功耗小于10 mW。Pervasive health service oriented wireless body area sensor network needs the network meet requirement of high speed and low power consumption.By using ultra wideband（UWB）technology,high speed and low power consumption wireless body area sensor network is constructed,according to the requirements of pervasive health.The network can support multiple sensor detection at the same time,through high speed physical layer interface,physiological information can be transmitted in time.The prototype system measurement shows that the system can support more than 10 sensor nodes,and can provide network rate up to 100 Mbps at the range of 3m and the average power consumption of the sending nodes is less than 10 mW.
