物联网(IoT)设备数量和由这些设备生成的数据呈指数级增长，在本已拥挤的ISM 2.4-GHz频段引发了频谱危机。为了解决这一问题，并使物联网设备之间能够进行更灵活和并发的通信，我们提出了(BW2)-W-2，这是一种新型的通信框架，可以实现Wi-Fi和蓝牙低能量(BLE)设备之间的N路并发通信。具体地说，我们演示了在支持BLE到BLE以及Wi-Fi到Wi-Fi通信的同时，启用BLE到Wi-Fi的跨技术通信是可能的。我们在不同的真实环境下进行了广泛的实验，结果表明，它的吞吐量是最新报道的跨技术通信系统的85倍以上，后者在任何特定时间都只支持单向通信(即广播)。
The exponentially increasing number of Internet of Things (IoT) devices and the data generated by these devices introduces the spectrum crisis at the already crowded ISM 2.4-GHz band. To address this issue and enable more flexible and concurrent communications among IoT devices, we propose (BW2)-W-2, a novel communication framework that enables N-way concurrent communication among Wi-Fi and Bluetooth low energy (BLE) devices. Specifically, we demonstrate that it is possible to enable the BLE to Wi-Fi cross-technology communication while supporting the concurrent BLE to BLE and Wi-Fi to Wi-Fi communications. We conducted extensive experiments under different real-world settings, and results show that its throughput is more than 85X times higher than that of the most recently reported cross-technology communication system, which only supports one-way communication (i.e., broadcasting) at any specific time.
