Abstract

Bluetooth has, in recent years, gained more and more momentum. New commodity objects and wearables implementing Bluetooth Smart technology (Low Energy) are released everyday. In particular, the ever increasing number of discoverable devices both inside and outside a populated area gives us an encouraging insight on future research directions for this technology. In this paper, based on a sensing system developed as an Android application, we evaluate Bluetooth Classic and Low Energy discovery characteristics from a vehicular perspective. By recording information about devices nearby (e.g. the number of discovered devices, their signal strength, manufacturer information) and the GPS location we can derive interesting information about a driver's situation, as well as his/her environment. Presented results indicate that the amount of discovered devices and signal strengths are dependent on velocity and road category. Finally, future work and discussions address potential use-case applications based only on Bluetooth discovery, such as low energy and privacy friendly road and traffic context awareness. The sensing system used in this article is free online under the MIT License.

在车辆环境中描述蓝牙发现

近年来，蓝牙技术获得了越来越多的发展势头。实现蓝牙智能技术(低能耗)的新商品和可穿戴设备每天都在发布。特别是，人口密集地区内外可发现的设备数量不断增加，这给了我们对这项技术未来研究方向的鼓舞人心的见解。本文基于Android应用开发的传感系统，从车载角度评估了蓝牙经典和低功耗发现特性。通过记录附近设备的信息(例如发现设备的数量、它们的信号强度、制造商信息)和GPS位置，我们可以获得有关驾驶员情况以及他/她所处环境的有趣信息。结果表明，发现设备的数量和信号强度取决于速度和道路类别。最后，未来的工作和讨论将解决仅基于蓝牙发现的潜在用例应用，例如低能耗和隐私友好的道路和交通环境感知。本文中使用的传感系统在MIT许可下是免费在线的。
