In recent years, the booming of Internet of Things (IoT) has populated the world with billions of smart devices that implement novel services and applications. The potential for cyberattacks on IoT systems have called for new solutions from the research community. Remote attestation is a widely used technique that allows a verifier to identify software compromise on a remote platform (called prover). Traditional challenge-response remote attestation protocols between the verifier and a single prover face a severe scalability challenge when they are applied to large scale IoT systems.

Visible Light Communication (VLC) offers a key alternative to the spectrum-challenged Radio Frequency (RF)-based forms of data transmission by tapping an unutilized and unregulated frequency band. Carefully designed low-cost VLC devices have the potential to enable the Internet of Things (IoT) at scale by reducing the current RF spectrum congestion, which is one of the major obstacles to the pervasiveness of the IoT. Wide adoption of VLC devices is however hindered by their current shortcomings, including low data rate, very short range and inability to communicate in noisy environment.

Networks of IoT devices often require configuration and definition of behavior by the final user. Node-RED is a flow-based programming platform commonly used for End User Development, but it requiresnetworking and protocols skills in order to be efficiently used. We add a level of abstraction to Node-REDnodes in order to allow non-skilled users to configure and control networks of IoT devices and onlineservices. We applied such abstractions to the SeismoCloud application for earthquake monitoring

The rapid development and adoption of Internet and digital technologies
dramatically changed business processes, leading to a disruptive digital transformation
of the whole industry value chain. The so-called Industry 4.0 refers to a
complex evolution of the entire industrial sector that includes technological
advances in production equipment (i.e. Additive Manufacturing), smart finished
products (IoT), data tools and analytics, involving activities and stakeholders at all

This paper reports on innovative teaching interventions in the frame of Internet of Things (IoT) design ideation classes. A card-based gamification approach has been applied in two different engineering masters courses. The participating students had already a good understanding of IoT technologies and they were asked to produce innovative designs by using them. We examine here the produced design ideas and the students’ perception of the collaborative design process and tools.

Heart disease and stroke are becoming the leading causes of death worldwide. Electrocardiography monitoring devices (ECG) are the only tool that helps physicians diagnose cardiac abnormalities. Although the design of ECGs has followed closely the electronics miniaturization evolution over the years, existing wearable ECGs have limited accuracy and rely on external resources to analyze the signals and evaluate heart activity. In this paper, we work towards empowering the wearable device with processing capabilities to locally analyze the signal and identify abnormal behaviour.

In this paper, we look into smart water metering infrastructures that enable continuous, on-demand and bidirectional data exchange between metering devices, water flow equipment, utilities and end-users. We focus on the design, development and deployment of such infrastructures as part of larger, smart city, infrastructures. Until now, such critical smart city infrastructures have been developed following a cloud-centric paradigm where all the data are collected and processed centrally using cloud services to create real business value.

To exploit the LoRaWAN (Long-Range Wide Area Network), it is essential to design suitable allocation schemes for the wireless resources. To this aim, strategies for a fair allocation of Spreading Factors (SF) among the network devices have been presented. These strategies greatly outperform the basic Adaptive Data Rate (ADR) scheme. Within these techniques, EXPLoRa-AT yields so far the best results exploiting an 'ordered water-filling' approach which aims to equalize the Air-Time channel usage for each group of devices using the same SF.

The purpose of this paper is to illustrate a multidisciplinary model for safety and security management (IMMSSM) which can be implemented by means of a suitable Integrated Technological System Framework (ITSF) that can be based on Internet of Things (IoT)/Internet of Everything (IoE), showing also the significant role played by the integration of the elements that compose the model itself, thanks to a proper genetic algorithm studied for the specific context.
