论文摘要
相互连接的传感器和执行器已扩展到小型嵌入式设备，例如可穿戴设备，同时在Internet Edge上遇到了大规模部署：物联网（IoT）。这些物联网设备中的许多设备都在低功率电池上运行，并被迫在非常有限的资源上运行，即CPU，小记忆和低功率收音机。在此制度中，建立一个能节能，无线且仍然覆盖广泛区域的网络基础架构是一个更大的挑战。洛拉（Lora）是一种低复杂的远程无线电技术，它试图应对这些挑战。洛拉万（Lorawan）已建立了广泛部署的网络模型，它享有开放的公共洛拉瓦族传播，例如通过Thethingsnetwork的基础设施。在本文中，我们报告了我们在汉堡莫妮卡项目的一部分中开发和部署基于洛拉的智能城市应用程序的经验。我们的贡献是双重的。首先，我们描述了基于友好的物联网操作系统暴动的端到端物联网应用程序的设计和实施。其次，我们在汉堡市的几次公共事件中报告了对大型现场试验的测量和评估。我们的结果表明，Lorawan为各种智能城市用例和物联网应用提供了合适的通信层，但也确定了其局限性和弱点。
Inter-connected sensors and actuators have scaled down to small embedded devices such as wearables, and at the same time meet a massive deployment at the Internet edge: the Internet of Things (IoT). Many of these IoT devices run on low-power batteries and are forced to operate on very constrained resources, namely slow CPUs, tiny memories, and low-power radios. Establishing a network infrastructure that is energy efficient, wireless, and still covers a wide area is a larger challenge in this regime. LoRa is a low complexity long range radio technology, which tries to meet these challenges.With LoRaWAN a network model for widespread deployment has been established, which enjoys open public LoRaWAN dissemination such as with the infrastructure of TheThingsNetwork. In this paper, we report about our experiences with developing and deploying LoRa-based smart city applications as part of the MONICA project in Hamburg. Our contributions are twofold. First, we describe the design and implementation of end-to-end IoT applications based on the friendly IoT operating system RIOT. Second, we report on measurements and evaluations of our large field trials during several public events in the city of Hamburg. Our results show that LoRaWAN provides a suitable communication layer for a variety of Smart City use-cases and IoT applications, but also identifies its limitations and weaknesses.
