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。

With the approaching of an aging society, wireless personal medical network is considered as the key to solve the contradiction between the shortage of medical resources and the aging population. Therefore, the wireless local area network has attracted more and more attention. The traditional wireless body area network faces the demand of the sensor of the low speed, can not meet the needs of different sensors of different speed and low consumption requirement that many sensors need at the same time. This article builds a wireless body area network based on ultra-wideband technology. By combining ZIGBEE technology with ultra-wideband technology, the network can meet the requirements of multi-node, low power consumption, low latency and high speed. The analysis and experimental results show that the wireless body area network can meet the requirements of more than 10 nodes simultaneously, the transmission delay is less than 100ms and the power consumption of single node is less than 10mW.
