“…Amongst publish-subscribe protocols, several stand out, such as Message Queuing Telemetry Transport (MQTT) and Data Distribution Service (DDS). In [22], an evaluation emphasizes that DDS outperforms MQTT by comparing latencies, which highlights its real-time capabilities. The DDS-based network is composed of topics, an application-specific data domain made by the user e.g.…”

Since the expansion of the Internet of Things (IoT), connected devices became smart and autonomous. Their exponentially increasing number and their use in many application domains result in a huge potential of cybersecurity threats. Taking into account the evolution of the IoT, security and interoperability are the main challenges, to ensure the reliability of the information. The blockchain technology provides a new approach to handle the trust in a decentralized network. However, current blockchain implementations cannot be used in the IoT domain because of their huge need for computing power and storage utilization. This paper provides a lightweight distributed ledger protocol dedicated to the IoT application, reducing the computing power and storage utilization, handling the scalability and ensuring the reliability of the information.

“…It brings all the software and hardware building blocks to decentralize processing to the edges of the network. In [21], we were introducing this project combining local processing, with completely decentralized communications and configurability, so that a network can cooperate in the most efficient way. As a point of comparison, the Open IoT gateway in [22] is very configurable, but operates on a Cloud-based network, and the Smart Gateway presented in [23] uses Message Queuing Telemetry Transport as a communication protocol, while we chose Data Distribution Service as the communication protocol.…”

“…In terms of communication protocol, in the context of IoT especially for edge-computing purposes, the publish-subscribe pattern is more appropriate than server-client. It has been demonstrated in [21] that Data Distribution Service (DDS) outperforms Message Queuing Telemetry Transport (MQTT) when comparing latencies, which emphasizes its real-time capabilities, despite that bandwidth requirements are larger for DDS. However, the fact that data are potentially processed locally in the gateway decreases bandwidth needs.…”

The Internet of Things is a promise of smarter technologies, with devices working together in a distributed manner, to provide more quality of service in many domains, such as industry, transports, energy, health, etc. Fog/Edge computing is probably one of the most interesting concepts as it will be a means to optimize energy and performance. However, beyond the principle, few works have really demonstrated the real potential of it, as many challenges need to be addressed at different levels: hardware design, software APIs, communication protocols, radio technologies, and so on. In this context, there is a growing interest in reconfigurable devices, as they bridge the gap between performance and energy with the advantage of the hardware flexibility. In this paper, we present a platform with sensor nodes and gateways relying on FPGAs, and showing that reconfigurable devices can be an enabling technology for edge-computing.

“…No estado atual das tecnologias de comunicação, predominam as arquiteturas centralizadas em data centers, com o compartilhamento de recursos através de serviços baseados em nuvem (cloud-based services), concentrando o poder de processamento e armazenamento nos data centers. Esse modelo de arquitetura pode se tornar insustentável para o contexto das IoTs, não havendo precedentes em termos da quantidade de dispositivos conectados, impondo alta carga de requisições frente aos desa os inerentes à latência de rede, largura de banda, con abilidade e segurança (Laurent et al, 2018).…”

“…Nesse modelo, provê-se os dispositivos/objetos com maior capacidade de processamento, armazenamento e comunicação, a m de diminuir o volume e a frequência de troca de informações oriúndas desses dispositivos. Desta forma, equipa-se melhor a borda da rede (com a adoção de gateways), possibilitando uma gerência mais acurada em termos de atuação sobre os objetos e de comunicação da borda com a nuvem (Laurent et al, 2018). Ou seja, no modelo baseado estritamente na nuvem, a inteligência dos dispositivos está centrada em um único ponto e resultando, sobretudo, em altas latências e mesmo indisponibilidade de atuação e controle sobre os objetos.…”

Com o avanço tecnológico e barateamento de recursos computacionais, tem-se equipado objetos convencionais com alguma forma de computação e comunicação que possibilitam, inclusive, a sua conexão à Internet. A esse cenário heterogêneo de conectividade à Internet que se denomina Internet of Things (IoT - Intenet das Coisas). Convencionalmente, recorre-se à computação em nuvem (cloud computing) para viabilizar a operacionalização das soluções em IoT. No entanto, fatores que influenciam na conectividade dos dispositivos com a infraestrutura na nuvem podem afetar a implantação e interação com os dispositivos. Para trazer o controle mais próximo destes, introduziu-se o paradigma de fog computing que, em síntese, traz as principais facilidades da nuvem para próximo de onde realmente estão os dispositivos. Este trabalho compara a solução baseada em nuvem e a solução em fog via estudos de caso desenvolvidos em uma plataforma de IoT. Os resultados indicam que há benefícios significativos da solução baseada em fog, sobretudo em termos de redução do atraso de comunicação com os dispositivos.
