The Industrial Internet of Things (IIoT) is one of the most demanding IoT applications. The insertion of industries in the context of smart cities and other smart environments, allied with new communication technologies such as 5G, brings a new horizon of possibilities and new requirements. These requirements include low latency, the support of a massive quantity of devices and data, and the need to support horizontal communications between devices at the edge level. To make this feasible, it is necessary to establish an IIoT-to-cloud continuum distributing federated brokers across the infrastructure and providing scalability and interoperability. To attend this type of application, we present the Helix Multi-layered IoT platform and its operating modes. We report and discuss its real-world deployment in the Aveiro Tech City Living Lab in Aveiro, Portugal with functional and performance tests. We tested device-to-device communication across edge and core layers and also interconnected the infrastructure with one in São Paulo, Brazil, replicating the use of a global industry. The successful deployment validates the use of a Helix Multi-layered IoT platform as a suitable backend platform for IIoT applications capable of establishing the IIoT-to-cloud continuum. It also helps for the deployment of other applications in such a domain.
Some types of FPGA (Field Programmable Gate Array) can be partially reconfigured during run-time forming a Partial Reconfigurable System (PRS). The use of PRSs brings several advantages like cost reduction. A larger use of PRSs faces a limiting factor: the difficult to access and use appropriate development tools. This work shows the PRSs, its applications and an analysis of the the existing development tools. Later, it dedicates to the improvement of one of these tools, the PARBIT, developing a graphical user interface (GUI) and updating its project methodology. The project methodologies supported by the manufacturer of the FPGA are also presented. The methodologies are validated through the design of a PRS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
