LoRaWAN低功耗广域网中的D2D通信：从构想到经验验证
D2D Communications in LoRaWAN Low Power Wide Area Network: From Idea to Empirical Validation
摘要：
在本文中，我们提倡在LoRaWAN低功率广域网（LPWAN）中使用设备到设备（D2D）通信。在概述了LoRaWAN技术的关键特征之后，我们讨论了为其启用D2D通信的优点和缺点。随后，我们提出了一种网络辅助D2D通信协议，并通过在LoRaWAN认证的商业收发器上实现它来展示其可行性。所进行的实验表明所提出的D2D通信协议的性能，使我们能够评估其性能。更准确地说，我们表明，与传统的LoRaWAN数据传输机制相比，D2D通信可以将数据传输的时间和能量减少6到20倍。另外，D2D通信的使用可以通过实现频率资源的空间重用而对网络具有积极影响。所提出的LoRaWAN D2D通信可以用于需要高覆盖的各种应用，例如用于管理和交易的分布式智能电网部署中的用例。
英文摘要：
In this paper we advocate the use of device-to-device (D2D) communications in a LoRaWAN Low Power Wide Area Network (LPWAN). After overviewing the critical features of the LoRaWAN technology, we discuss the pros and cons of enabling the D2D communications for it. Subsequently we propose a network-assisted D2D communications protocol and show its feasibility by implementing it on top of a LoRaWAN-certified commercial transceiver. The conducted experiments show the performance of the proposed D2D communications protocol and enable us to assess its performance. More precisely, we show that the D2D communications can reduce the time and energy for data transfer by 6 to 20 times compared to conventional LoRaWAN data transfer mechanisms. In addition, the use of D2D communications may have a positive effect on the network by enabling spatial re-use of the frequency resources. The proposed LoRaWAN D2D communications can be used for a wide variety of applications requiring high coverage, e.g. use cases in distributed smart grid deployments for management and trading.
