Abstract

In this paper, we consider the problem of detecting the channel activity in LoRaWAN networks. To improve the medium access performance, recent implementations of the chipsets for LoRaWAN end nodes are offering a feature called Channel Activity Detection (CAD), as the first step toward the implementation of the Carrier Sense Multiple Access (CSMA) in LoRaWAN networks. The algorithm underlying the CAD is at the moment left undisclosed. In this paper, we propose a possible implementation of the CAD algorithm; we then evaluate its performance in an additive white Gaussian noise (AWGN) channel, and we find the performance being completely satisfactory and matching the one of the undisclosed algorithm. The results we find are encouraging the community to include the CAD feature in open source implementations of a LoRaWAN receiver.

关于 LoRaWAN 网络中的信道活动检测

本文探讨了 LoRaWAN 网络中的信道活动检测问题。为了提高介质访问性能，LoRaWAN 终端节点芯片组的最新实现提供了一种名为信道活动检测（CAD）的功能，作为在 LoRaWAN 网络中实现载波感应多路访问（CSMA）的第一步。目前，CAD 的基本算法尚未公开。在本文中，我们提出了一种可能的 CAD 算法实现方法；然后，我们评估了其在加性白高斯噪声（AWGN）信道中的性能，发现其性能完全令人满意，与未公开算法的性能相匹配。我们所发现的结果鼓励社区将 CAD 功能纳入 LoRaWAN 接收器的开源实现中。
