Low-power and long-range communication networks (including LoRa, MIoTy, NB-IoT for sensor networks and the Internet of Things) have recently attracted increasing research interest and efforts. Despite the rapid development, there are still many challenges and unsolved problems in this area with respect to large-scale real-world applications. Especially in applications that cover large areas, are located in remote and hard-to-reach places, or in hazardous areas, reliable communication without existing infrastructure is the immense advantage of Low-power and long-range technologies. At the same time, this is also the challenge, because the sensors and networks must be self-sufficient, reliable and available over a long period of time. In addition to the various requirements for wireless communication, the low-power aspects in particular therefore also play a major role, because without sufficient energy efficiency, the practical use of such networks is not expedient.
Based on hardware architectures and novel platforms, large-scale networks can be established using robust and efficient transmission technologies such as LoRa, MIoTy or NB-IoT. For this, protocols and network management are indispensable, which always consider the aspects of reliability, transmission range and energy efficiency. These methods also have in common that greater robustness and longer transmission distances are achieved at the expense of bandwidth. In this context, on-sensor data processing for bandwidth reduction is an important key to future low-power and long-range network architectures, while overlying network management and integration into existing IoT structures must also be considered.
The goal of this workshop is to bring together researchers from academia and industry to address the challenges and opportunities in the design, development, implementation and deployment of wireless low power and long range sensors and networks on every layer.
