Electric Storage Water Heaters are the devices that are primarily used on the island to produce domestic hot water. Starting from measured load profiles collected in Lampedusa, a domestic hot water consumption profile was derived, to simulate the energy usage of the Storage Water Electric Heaters during the day. This work was carried out as a preliminary feasibility study for the BloRin project, financed by cohesion funds in the Sicilian region. According to the project, which also includes the installation of domestic photovoltaic systems on the island, two development scenarios have been formulated. The results show that even a limited penetration of photovoltaic power in the energy system of Lampedusa can lead to steep load ramps and risk of power inversion in distribution substations. To overcome these problems, several Demand Response programs have been considered. By setting a higher value of the desired water temperature of the Storage Water Electric Heaters, in the hours of maximum photovoltaic generation, thermal loads can be shifted towards central hours of the day, with clear benefits in terms of power inversion containment and peak reduction.

The IoT paradigm enables the intertwined use of physical and soft- ware components through the interconnection of devices that exchange data with each other without direct human interaction in several fields, especially in industrial and home environments. In the framework of the Italian-Vietnamese cooperation on the topics of smart cities and Blockchain, we present two applications of the blockchain technology, which can be applied, respectively in indoor, for monitoring and controlling smart homes, and in outdoor, for visual monitoring through video surveillance systems. In both cases, we propose decentralised architectures that aim at solving common IoT problems and vulnerabilities, with a specific focus on pri- vacy issues. The introduced flexibility, extensibility and security in indoor IoT en- vironments and outdoor video surveillance systems permit to foresee smarter cities that assist citizens with innovative services both in indoor and outdoor environ- ments. We propose a reinterpretation of the role of the IoT gateway, making it blockchain-aware and handling IoT transactions without a central trusted authority. As for video surveillance, we focus on two different directions. First, we provide the capability to analyse multiple video-flows from different cameras deployed around the city by heterogeneous owners, guaranteeing the integrity of the timestamps and camera settings. Second, the system ensures that the positions of cameras, their orientation and their mechanical parameters are not physically ma- nipulated; otherwise, the platform generates a warning. We guarantee citizens' pri- vacy monitoring and tracking camera settings and storing video flows. The absence of digital and physical manipulations guarantees citizens against possible violations of their privacy. To face these risks, we introduce a blockchain-based video surveil- lance system that jointly provides validation and immutability to camera settings and surveillance videos, making them readily available to authorised users in case of events and paving the way to new distributed city-wide monitoring systems

In order to mitigate fading events that occur in FSO communications, we have also tested the performance of three different families of Rateless Codes (Luby Transform, Raptor and RaptorQ) into our model and found that RaptorQ is the best candidate to mitigate errors in FSO links.

Cyber-physical systems include physical and software components for providing smart monitoring and control with flexibility and adaptability to the operating context. The IoT paradigm enables the intertwined use of physical and software components through the interconnection of devices that exchange data with each other without direct human interaction in several fields, especially in industrial and home environments. We propose DeCyMo, a decentralized architecture that aims at solving common IoT issues and vulnerabilities leveraging the centralized structure of IoT and the distributed architecture of the blockchain. Our experimental setup uses Docker containers on the IoT gateway and the Multichain blockchain for handling validated transactions without a central trusted authority. Preliminary results demonstrate the flexibility, the extensibility and the security of DeCyMo in industrial and home environments through a reinterpretation of the role of the IoT gateway
