Abstract

Body sensor networks (BSN) are an important research topic due to various advantages over conventional measurement equipment. One main advantage is the feasibility to deploy a BSN system for 24/7 health monitoring applications. The requirements for such an application are miniaturization of the network nodes and the use of wireless data transmission technologies to ensure wearability and ease of use. Therefore, the reliability of such a system depends on the quality of the wireless data transmission. At present, most BSNs use ZigBee or other IEEE 802.15.4 based transmission technologies. Here, we evaluated the performance of a wireless transmission system of a novel BSN for biomedical applications in the 433MHz ISM band, called Integrated Posture and Activity NEtwork by Medit Aachen (IPANEMA) BSN. The 433MHz ISM band is used mostly by implanted sensors and thus allows easy integration of such into the BSN. Multiple measurement scenarios have been assessed, including varying antenna orientations, transmission distances and the number of network participants. The mean packet loss rate (PLR) was 0.63% for a single slave, which is comparable to IEEE 802.15.4 BSNs in the proximity of Bluetooth or WiFi networks. Secondly, an enhanced version is evaluated during on-body measurements with five slaves. The mean PLR results show a comparable good performance for measurements on a treadmill (2.5%), an outdoor track (3.4%) and in a climate chamber (1.5%).

摘要

体域网（BSN）是一个重要的研究课题，因为它具有许多优于传统测量设备的优势。一个主要的优势是能够部署 BSN 系统进行 24/7 健康监测应用。对于这样的应用，需要将网络节点小型化，并使用无线数据传输技术来确保可穿戴性和易用性。因此，这样的系统的可靠性取决于无线数据传输的质量。目前，大多数 BSN 都使用 ZigBee 或其他基于 IEEE 802.15.4 的传输技术。在这里，我们评估了一种新型 BSN 的无线传输系统在生物医学应用中的性能，该系统称为由 Medit Aachen（IPANEMA）BSN 开发的综合姿势和活动网络。433MHz ISM 频段主要用于植入式传感器，因此可以很容易地将其集成到 BSN 中。已经评估了多种测量场景，包括不同的天线方向、传输距离和网络参与者的数量。单个从机的平均分组丢失率（PLR）为 0.63%，这与蓝牙或 WiFi 网络附近的 IEEE 802.15.4 BSN 相当。其次，在有五个从机的体上测量中评估了增强版本。平均 PLR 结果表明，在跑步机（2.5%）、户外跑道（3.4%）和气候室（1.5%）上的测量表现相当良好。
