“…A LoRa também se caracteriza pela redução na complexidade do hardware, a diminuição do tamanho dos cabeçalhos e da complexidade da rede em termos de saltos e endereçamento, proporcionando uma comunicação bidirecional simples, com o uso de uma infraestrutura mínima e com baixo consumo de energia. O LoRaWAN [Marais et al, 2017] define a arquitetura do sistema e o protocolo de controle acesso ao meio (Medium Access Control -MAC) que utiliza a camada física LoRa. O LoRaWAN define taxas de velocidade de dados, suporte à comunicação bidirecional e oferta de serviços de mobilidade e localização dos nós da rede.…”

Serviços baseados em localização permitem o monitoramento de pessoas ou áreas específicas. Através do acompanhamento da sua localização, é possível auxiliar o resgate de pessoas perdidas ou acidentadas em ambientes naturais. No entanto, as redes sem-fio em áreas de densa vegetação, neste caso, a Mata Atlântica, implicam desafios relacionados com mobilidade e conectividade. Este trabalho compara o desempenho em termos de alcance, potência do sinal, taxa de perda e atraso em enlaces implementados usando as tecnologias LoRa, IEEE 802.11g e ZigBee no Parque Nacional da Serra dos Órgãos. A comparação destas métricas permite distinguir as limitações de cada tecnologia que podem influenciar na disseminação de alertas. Os resultados mostram que o alcance máximo da LoRa é 3 vezes maior do que o IEEE 802.11g e 6 vezes maior do que o ZigBee, com potência do sinal recebido menor que as duas tecnologias, em média 21,67% e 26,15%, respectivamente.

The Internet of Things is one of the hottest topics in communications today, with current revenues of $151B, around 7 billion connected devices, and an unprecedented growth expected for next years. A massive number of sensors and actuators are expected to emerge, requiring new wireless technologies that can extend their battery life and can cover large areas. LoRaWAN is one of the most outstanding technologies which fulfill these demands, attracting the attention of both academia and industry. In this paper, the design of a LoRaWAN testbed to support critical situations, such as emergency scenarios or natural disasters, is proposed. This self-healing LoRaWAN network architecture will provide resilience when part of the equipment in the core network may become faulty. This resilience is achieved by virtualizing and properly orchestrating the different network entities. Different options have been designed and implemented as real prototypes. Based on our performance evaluation, we claim that the usage of microservice orchestration with several replicas of the LoRaWAN network entities and a load balancer produces an almost seamless recovery which makes it a proper solution to recover after a system crash caused by any catastrophic event.

“…This gateway captures the LoRa packets which are transmitted by the end nodes (e.g., Pysense sensor shield) and then these packets are scanned and forwarded to their destination. Generally, the nearby gateway captures the transmission of LoRa packets [19]. To set up the hardware Laird Sentrius RG1xx gateway, we need to follow the steps below.…”

Internet of Things (IoT) is not new in the market; however, they are becoming more dominant in various operations and applications. These pervasive infrastructures can collect different data in a given environment such as temperature, pressure, light sensitivity, and so on to enable remote condition monitoring. Subsequently, these collected data can be used for many purposes depending on the user's requirement. Currently, there are colossal interests from researchers to know how to use these infrastructures to collect and send data over different protocols to the cloud for efficient remote handling from anywhere in the world. In this paper, we design and implement an infrastructure based on Pycom development board FiPy and sensor shield Pysense to collect and send data to the remote cloud over Wi-Fi and Long Range (LoRa) protocols. The intelligible set up is beneficial for observing and managing data in the cloud.
