摘　　要：随着老龄化社会的临近,无线个人医疗网络被认为是解决医疗资源短缺与老龄化人口增多矛盾的关键,因而无线体域网日益受到关注。传统的无线体域网面向低速率的传感器需求,无法满足多个传感器同时监测需要的不同速率和低功耗要求。该文以超宽带技术为基础构建无线体域网。通过采用ZIGBEE技术与超宽带技术相结合,该网络能够满足多节点、低功耗、低延时、高速的要求。分析和实测结果表明:该无线体域网能够满足10个节点以上同时使用,传输延迟小于100ms,单节点功耗小于10mW。As society ages, wireless personal medical networks will be a key part of improving e-health solutions. Thus, wireless body area networks （WBANs） are receiving more and more attention. Traditional WBANs have mainly used low speed sensors, which cannot meet the needs of various speeds and low powers of multiple sensor nodes simultaneously monitoring applications. This paper presents a heterogeneous wireless network based on the single carrier ultra wide band （SC-UWB） and ZIGBEE technologies. This network supports multiple sensor nodes with low power, low-latency and high speed operation. Analyses and experimental results show that the network can support at least 10 sensor nodes. The network packet delay is less than 100 ms and each single sensor node consumes less than 10 roW.
