摘要:
 近年来,伴随着传感器技术和通信技术的不断革新,无线体域网(WBAN)在医疗健康领域中的作用愈发明显.WBAN的特点与无线传感网(WSN)有很大的区别,它每个传感器都拥有独特的用途.WBAN在远程诊断、特殊人群实时监测和社区医疗等领域存在巨大的潜能和应用前景.但是,WBAN的供电方式一般为电池供电,其能量有限,计算存储、无线通信的能力不高,特别是对于植入节点,不可频繁更换电池.针对WBAN中业务种类的异构性,通过分析无线个域网IEEE802.15.4标准,设计了一种基于时隙ALOHA的新MAC协议.它能够在紧急情况下区分和首选各种类型的业务,保证紧急业务的优先传输.通过仿真进行了性能分析,结果表明,与现有的MAC协议相比,该协议在能耗、丢包数、吞吐量等方面有显著提升.
Abstract:
 In recent years,along with continuous innovation of the sensor technology and communications technology,Wireless Body Area Network (WBAN) plays an important role in healthcare field.The characteristics of WBAN is different from Wireless Sensor Network (WSN),and each sensor of it has a unique purpose.WBAN has great potential and prospects in remote diagnostics,special populations monitoring and community medical care.However,WBAN is battery-powered,energy of which is limited,and computing and storage,wireless communications capabilities are not high,especially for embedded nodes do not frequent replacement of batteries.In view of heterogeneousness of data types for WBAN,by analyzing the IEEE802.15.4 wireless personal area network standard,a new MAC Protocol based on slotted ALOHA is designed.It can distinguish in emergency situations to ensure the priority transmission of emergency operations.The performance is analyzed with simulation,and the results show that compared with existing MAC Protocol,it has significant improvement in the energy consumption,number of packets,throughput and so on.
