Long-range (LoRa) has become one of the vital parts of IoT communication. In this study, the real-time deployments of an unmanned aerial vehicle (UAV)-based LoRa communication network are systematically reviewed, with a focus on the communication setup and its reported performance.

2024年9月25日 · With the flight advantage of height, mobility, and flexibility, UAV can provide line-of-sight (LOS) communication or more reliable communication in many scenarios, which can be used to enhance the LoRaWAN network’s performance. In this paper, a novel UAV-assisted LoRaWAN network is designed and implemented.

2023年2月21日 · LoRa is a PHY-layer LPWAN technology that provides long-range communication at low data rates. Due to its scalability, low power consumption, and ease of deployment, LoRa technology has gained a lot of attention from researchers recently.

LoRa的特点是，使用较低的功耗及发射功率，在较低空中速率的条件下完成超远距离的数据传输，完美！ 实际上目前已经有大量的无人机企业已经在开发或者在应用LoRa数传电台，国内有大量的FPV飞行（算是简易的无人机，主要用于航拍）爱好者在追求极致远的道路上毅然选择了基于LoRa技术的遥控+ 数据链系统。 实际飞行时在433/915频段仅500mw的功率可以在40-60km的距离上完成双向数据交互，稳定的遥控飞机飞行。 行业应用中也有基于 LoRa技术 的遥控数据一 …

2023年6月5日 · In this paper, the problem of the flying LoRa (FL) gateway control in the search-and-rescue system using the UAV-assisted LoRa network is modeled as a partially observable Markov decision process. Then, a deep meta-RL-based policy is proposed to control the FL gateway trajectory during SAR operation.

2023年6月2日 · Among the LoRa applications, unmanned aerial vehicles (UAV) systems are emerging with the benefits of extended battery life and a long communication range. In this paper, we investigate the network capacity with the mixture of concurrent and sequential transmission (MCST) scheme over LoRa networks.

To overcome this challenge, using unmanned aerial vehicles (UAVs) as a flying LoRa gateway to transfer messages from ground LoRa nodes to the ground rescue station can be a promising solution. In this paper, an artificial intelligence-empowered SAR operation framework using a UAV-assisted LoRa network in different unknown search environments is ...

This work considers a scenario where LoRa End Devices (LoRa-EDs) are randomly scattered and stationary, and LoRa Gateways (LoRa-GWs) are mounted on UAVs. We also assume that each gateway connects to a 5G BS with unlimited capacity.

Why LoRa? Lora is one of the promising IoT technologies that deliver communication for areas where availability of power grid is limited or it doesn’t exist. Most of the world by now, is also familiar with drones or aerial vehicles (UAV), that operate wherever possible.

2023年11月17日 · To overcome this, we propose two reinforcement learning (RL) algorithms, Q-learning and deep Q-network (DQN), for energy-efficient data transmission over a hybrid BLE/LTE/Wi-Fi/LoRa UAV-assisted wireless network. We consider BLE, LTE, Wi-Fi, and LoRa for communication over a UAV-GS link.
