The development of smart cyberinfrastructures on the basis of the Internet of Things has caused the penetration of new technologies into the spheres of unmanned transportation, robotic buildings, and digital economy, and then, as a result of the integration of cyber-physical systems with monitoring, analytical, and control means, a new intelligent urban paradigm of a ‘smart city’. Noting the high criticality of this system, specific threats are aimed at disrupting its connectivity, resource capturing, functional availability, data privacy, and safety. As a protective measure, blockchain is a usual part of the security arsenal of any distributed system, providing provable security to all its participants. However, in a large-scale smart city's cyberinfrastructure, blockchain itself becomes a target of specific cyber threats, e.g., a ‘51% attack’. Also, the blockchain's usability issue is the unlimited growth of its structure, leading to exhaustion of free resources and thus depressing its use. Conventional approaches to preventing the blockchain from these issues downgrades its scalability and therefore are not widely applicable in a smart city. This paper proposes a new technique to protect the blockchain applied in a large-scale smart city network infrastructure. The proposed solution combines assessing the intruder's capabilities and providing dynamic adaptation of the blockchain to evolving threats. To avoid infinite growth of the blockchain, the blockchain with a floating genesis block and fixing blocks has been implemented. The developed modifications retain the ability to scale the blockchain. The experimental study has demonstrated the effectiveness of the proposed approach.

Water is one of the most important resources nowadays, which is why a good management can bring multiple benefits in modern society. With the continuous increase of water consumption, there is significant research regarding the efficiency of water control and monitoring process, in order to make optimal decisions for the proper functioning of a healthy eco-system. In the current paper we present a system that uses a water distribution network to evaluate the integration of modern concepts in a smart, secure and distributed approach for consumer demand monitoring. An IoT architecture is used for collecting data from smart meters, with push-based data exchange and reactive programming patterns. The network is integrated with a blockchain solution developed using Hyperledger Fabric to ensure an additional layer of security and transparency, while being used as an audit tool as well as data provider for decision support systems.

Platooning shows the potential to increase the efficiency and safety of future road traffic. Many researches illustrate its efficiency in highway scenarios where it is restricted to one lane. However, the biggest challenges lies in urban environments. Indeed, they are characterized by low-speed limits, intersections, traffic lights, buildings, vulnerable users..etc. We propose in this paper an Edge Cloud Vehicle-to-everything (V2X) architecture for full dynamic Platoon management in urban environments. We describe in this paper the overall phases of a Platoon, while considering the Cooperative Adaptive Cruise control (C-ACC) function and the traffic light intersection. We focused in this paper on two main contributions: First, the V2X exchanges;indeed we created a new type of intelligent Transportation Systems (ITS) message called ECEmessages based on the Cooperative-ITS (C-ITS) message structure as Cooperative Awareness Message (CAM), Decentralized environmental Notification Message (DENM), Signal Phase and Timing (SPAT), and Map message (MAP). Then, in order to test the effectiveness of our proposal, we used the Gazebo ROS simulator. We performed the performance evaluations of the proposal by providing a mapping between the importance of the V2X communications, which is measured in terms of latency and reliability, and of the platoon, which is measured in terms of achievable inter-distance between vehicles.

In the field of aquaculture, numerous studies indicate that traditional fishkeeping faces significant challenges due to the manual maintenance required, leading to inefficiencies such as inconsistent cleaning, feeding, and water quality management, that can be improved by integrating automation and smart technologies. This experimental research, conducted in Metro Manila, Philippines, aims to test and refine the Self-sustaining Fish Tank System. By evaluating the accuracy and effectiveness of integrated sensors and automated components, the study seeks to enhance the system's performance in maintaining optimal aquatic conditions. An experimental research approach was employed, utilizing multiple methods including observation for data collection. Quantitative data analysis using descriptive and paired two-test statistical tools assessed the performance of the Self-sustaining Fish Tank System using Arduino Uno. The study's findings highlighted significant improvements in sensor reliability and consistency during operational tests with and without fish. Specifically, the water level sensor demonstrated enhanced responsiveness during pump activations, while the pH sensor stabilized effectively with fish present. The fish feeder consistently dispensed food every 12 hours, ensuring reliable feeding throughout the study periods. The study concludes that variations in sensor performance, particularly in pH and turbidity measurements, highlight the need for continued refinement to ensure consistent control across different environmental conditions. Future research should explore advanced sensor integration for improved accuracy and reliability, especially for critical parameters like water quality. Additionally, the adoption of IoT-based solutions with wireless modules is recommended for enhanced real-time monitoring and remote control via mobile apps or web interfaces.

A farming method known as aquaponics aims to be a more effective response to the world's worries about food production and scarcity. In order to produce plants or vegetables in addition to fish to meet the rising global demand for food, this technique combines aquaculture (fish farming) and aquaponics (plants grown without soil). This technique or system promises to utilize less water, fertilizer, pesticides, and space while yet producing as much as conventional farming. The challenge is making it more usable and scalable for commercial and public use. To overcome such challenges, this technique must be intelligent and automated by rigorous sensing, monitoring, and system control. Our current research aims to develop a practical smart IoT-based aquaponics system. It offers a workable solution and ideas for further investigation while also looking for gaps in the earlier investigations.

Traditional healthcare systems are based on patients approaching physically to get themselves registered and avail of medical assistance. Also, the voluminous data entry into the centralized databases makes the process slow and insecure. Further, the system is unscalable and limited in nature. There are many instances where rural and remote area citizens were denied access to healthcare facilities due to a lack of technological reach. The advent of IoMT has proved to be a boon to the healthcare industry because they have facilitated Remote Patient monitoring (RPM) to store health information remotely in the form of Digital records or EHRs(Electronic Health Records). These devices are worn or implanted in the patients to get the data regularly and keep their health under scrutiny. However, these devices and the information they store are not secure. They are prone to malignant attacks, unauthorized tampering of health information, loss of vital and private information of the users, etc. Blockchain technology is an excellent solution to problems related to privacy and security, access and modification, control of information, forged information, and scalability. The blockchain offers decentralization of information distributed over a peer-to-peer network and stores data immutably. To a large extent, the problems currently faced in the healthcare industry are significantly mitigated. This paper proposes a smart healthcare system that uses IoMT devices coupled with blockchain in its back end. In addition, we have deployed a decentralized application to connect with patients remotely. We have proposed a method to run and deploy smart contracts using Ethereum and interaction between smart contracts and dApp. The results of the implementations are better than the existing systems regarding the security and privacy of patient data, eliminating intermediary costs while maintaining the quality of service through transparency and interoperability provided by Blockchain.
