长期以来，与传感器的通信要么局限于有线连接，要么局限于专有的无线通信协议。利用无处不在且价格低廉的无线通信技术创建传感器区域网络（san）将加速传感器技术的广泛部署。蓝牙是一种新兴的全球廉价本地无线通信标准，是san的可行选择，因为它固有地支持一些重要要求——低功耗、小尺寸、低成本和足够的通信范围。在本文中，我们概述了一种以蓝牙技术为中心的方法，以支持由固定无线传感器组成的传感器网络，用于高速公路、桥梁和其他民用基础设施的健康监测。我们提出了一种拓扑形成方案，该方案不仅考虑了不同传感器产生的流量，而且考虑了相关的链路强度、缓冲容量和能量可用性。该算法对节点的位置没有特别的假设，并且并非所有节点都需要彼此无线电接近。输出是植根于传感器集线器（数据记录器）的树形散射网，根据每个链路上承载的流量进行平衡。我们还分析了由此产生的传感器网络拓扑的调度、路由和修复方面。
Communicating with sensors has long been limited either to wired connections or to proprietary wireless communication protocols. Using a ubiquitous and inexpensive wireless communication technology to create Sensor Area Networks (SANs) will accelerate the extensive deployment of sensor technology. Bluetooth, an emerging, worldwide standard for inexpensive, local wireless communication is a viable choice for SANs because of its inherent support for some of the important requirements - low power, small form factor, low cost and sufficient communication range. In this paper we outline an approach, centered on the Bluetooth technology, to support a sensor network composed of fixed wireless sensors for health monitoring of highways, bridges and other civil infrastructures. We present a topology formation scheme that not only takes into account the traffic generated by different sensors but also the associated link strengths, buffer capacities and energy availability. The algorithm makes no particular assumptions as to the placement of nodes, and not all nodes need to be in radio proximity of each other. The output is a tree shaped scatternet rooted at the sensor hub (data logger) that is balanced in terms of traffic carried on each of the links. We also analyze the scheduling, routing and healing aspects of the resulting sensor-net topology.
