低功耗蓝牙（BLE）在广泛的应用中迅速而稳定地获得重要性。在本文中，我们调查的潜在BLE在车辆上下文中。通过实验，我们首先评估无线信道的特性，然后定义一组驾驶场景来分析BLE如何受到不同速度，距离和交通条件的影响。我们发现，两个设备之间的最大通信范围可以超过100米，并且即使在不同的交通和驾驶条件下，也可以在50米的距离内实现强大的连接，能够处理突然的信号丢失或干扰。然后，我们提出了一个概念验证的移动的应用程序，现成的智能手机，可用于传输数据的多跳。接下来，我们通过构建和验证基于IEEE 802.11技术的干扰测试平台，分析BLE如何处理同一频段上的其他干扰。最后，我们讨论了BLE的优点和局限性的车内通信（IVC），并提出了潜在的应用。(C)2015 Elsevier B.V.版权所有。
Bluetooth Low Energy (BLE) is quickly and steadily gaining importance for a wide range of applications. In this paper we investigate the potential of BLE in a vehicular context. By means of experiments, we first evaluate the characteristics of the wireless channel, then we define a set of driving scenarios to analyse how BLE is affected by varying speed, distance and traffic conditions. We found that the maximum communication range between two devices can go beyond 100 m and that a robust connection, capable of handling sudden signal losses or interferences, can be achieved up to a distance of 50 m even for varying traffic and driving conditions. We then present a proof-of-concept mobile application for off-the-shelf smartphones that can be used to transmit data over multiple hops. Next, we analyse how BLE handles other interferences on the same frequency band by building and validating an interference testbed based on the IEEE 802.11 technology. Finally we discuss the advantages and limitations of BLE for Inter-Vehicular Communications (IVC) and propose potential applications. (C) 2015 Elsevier B.V. All rights reserved.
