体域医学传感器网络的设计及其QoS性能分析
Design and QoS study of body area medical wireless sensor networks
【摘要】 提出医学无线传感器网络(MWSNs)的三层体系结构,并重点分析体域医学传感器网络的组成结构和网络传输需求。设计了基于IEEE802.15.4无线个域网协议的体域医学传感器网络(BA-MWSN),其拓扑结构采用星型,MAC采用时隙CSMA/CA机制。通过网络仿真评估了该BA-MWSN的QoS性能,分析表明:该网络能满足体域MWSNs的网络传输要求;设置合理的节点数量、网络负载和使用长帧可以获得较高的网络利用率和可靠性。
【Abstract】 We propose a 3-layers Medical Wireless Sensor Networks(MWSNs)for medical applicationsm,and analyze its architecture and its QoS requirements.Accordingly,IEEE802.15.4 based star Body Area-MWSNs(BA-MWSN) is designed by using slotted CSMA/CA MAC mechanism.The QoS of BA-MWSN is evaluated by network simulation experiment.The results indicate that the BA-MWSN can meet the requirements of body medical data transmission.Higher network throughput and reliability can be obtained with proper nodes number,network load and larger frame.
