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IEEE 802.15.4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 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.
