The increasing ability of internet-connected daily life electronic gadgets has propelled smart homes into a global trend. The Internet of Things (IoT) enables ambient devices to communicate and interact seamlessly through various sensors. Emerging technical concepts like Web3 and Industry 5.0 require decentralised and intelligent systems near the network's edge. Petabytes of IoT sensor-generated data cause a shortage of storage on the Cloud servers, adding a delay factor to the IoT system. Standard cloud-based IoT systems can't fully function in areas with unstable internet. This paper addresses these challenges and proposes a solution to integrate edge computing concepts. The proposed system is developed using a Raspberry Pi 3 Home Server (RHS) driven by the Support Vector Machine (SVM) algorithm. The designed prototype includes a fire and smoke detection system with MQ2 gas, dust, temperature, and flame sensors. The SVM and these sensors form a data fusion module integrating with Network Mapper (NMAP), Message Queuing Telemetry Transport (MQTT) broker, MariaDB SQL server, and InfluxDB time series database. The experiments demonstrate a fundamental edge operation with a latency of 2.45 ms (milliseconds), while NMAP integration ensures data security and device verification for sensor data storage. The synthetic simulations show positive outcomes for the data fusion-based monitoring system, where alerts are promptly triggered as sensor values change, with an overall system latency of approximately 24 ms. The developed system manages home automation, real-time monitoring for fire, smoke, gas leaks, network scans, anomaly detection, appliance usage tracking, and cloud data backup. A multi-level alert system ensures early threat mitigation, with alarms, SMS, notifications, and email alerts to maximize awareness.

Although the idea of communication between devices is not new, its developmenthas been rapid and significant since it helps people do their jobs more efficiently and keeps them fully informed of events at their homes and workplaces thanks to technology like the Blockchain (BC) based Internet of Things (IoT). However, this new technology suers from security issues and the existing research has not addressed these issues in depth. In this paper, a simulation of the smart network of the firefighting station was made. BC technology was used with one of the consensus algorithms which was proof of authority (PoA) to make this network more secure and private, in addition to the use of a hash function such as secure hash algorithm 384 (SHA-384), which is a one-way encryption function and was used to verify the BC data integrity so that it was dicult to hack the data and thus be the data transmission process is more secure. Also, the Espressif 32 (ESP32) device was chosen for this project because it oers several useful characteristics, including Wi-Fi and the capacity for rapid data transmission. It was observed from the results obtained from the application of consensus algorithms that the firefighting station network was made more secure and the PoA algorithm was better in several aspects such as execution time (maximum 0.4 S) and memory used (maximum 610 KB). Finally, the proposed work that was applied to the firefighting station was good in terms of safety and privacy, as the work of this station became more efficient.

For the past few years, the concept of the smart house has gained popularity. The major challenges concerning a smart home include data security, privacy issues, authentication, secure identification, and automated decision-making of Internet of Things (IoT) devices. Currently, existing home automation systems address either of these challenges, however, home automation that also involves automated decision-making systems and systematic features apart from being reliable and safe is an absolute necessity. The current study proposes a deep learning-driven smart home system that integrates a Convolutional neural network (CNN) for automated decision-making such as classifying the device as "ON" and "OFF" based on its utilization at home. Additionally, to provide a decentralized, secure, and reliable mechanism to assure the authentication and identification of the IoT devices we integrated the emerging blockchain technology into this study. The proposed system is fundamentally comprised of a variety of sensors, a 5 V relay circuit, and Raspberry Pi which operates as a server and maintains the database of each device being used. Moreover, an android application is developed which communicates with the Raspberry Pi interface using the Apache server and HTTP web interface. The practicality of the proposed system for home automation is tested and evaluated in the lab and in real-time to ensure its efficacy. The current study also assures that the technology and hardware utilized in the proposed smart house system are inexpensive, widely available, and scalable. Furthermore, the need for a more comprehensive security and privacy model to be incorporated into the design phase of smart homes is highlighted by a discussion of the risks analysis' implications including cyber threats, hardware security, and cyber attacks. The experimental results emphasize the significance of the proposed system and validate its usability in the real world.

Decentralization forms an integral part of democracy, arising from the conduction of elections.Modern democracies rely heavily on elections.However, there is a lack of trust building up due to the cases of discrepancies in the process.The "e-voting" system was developed after the 1960s.It overcame a lot of issues existing in the ballot voting system.In present times the significance of E-Voting has grown drastically.It cuts down the cost of hosting an election and increases the number of participants as they are free to cast their vote from any location, without any ballot boxes, or areas for establishing polling booths.There were still obstacles to overcome and deliver results.Even the most developed democracies, such as India and the United States, have error-prone voting processes.Voter fraud, EVM hacking, and polling station theft are the main issues with the current voting system.Reliability along with security and precision must be considered while performing elections.The blockchain with smart-contracts stands out as a leading candidate for developing more reliable, cost-effective, transparent, and user-friendly electronic voting systems.Undoubtedly, the revolutionary blockchain idea is the technology behind the cryptocurrency Bitcoin and its derivatives.Ethereum and its network are among the greatest because of their dependability and wide acceptance.An electronic voting system must be secure and transparent to avoid double voting and maintain privacy.In this study, we have used Ethereum wallet along with Solidity Programming language for developing a smart contact for Ethereum network that works as E-Voting System.

The major problem with the use of smart home technology is that it often leads to various security issues. This mainly happens because the devices use open internet connections that may be vulnerable and subjected to multiple threats, hackers, and viruses. Some household IoT devices are forcefully introduced to the market, exposing the customers to significant risk factors. The websites and links do not have any copyright information or any privacy policies, due to which the hackers may immediately steal the confidential information of the user. For instance, the door locking password may be hacked by cyber criminals, and they may use it to attack the home when there is nobody in the home. This paper presents how to use block-chain to improve home security.

It is the expansion and use of the Industrial Internet of Things (IIoT) in various industrial sectors and applications that are referred to as the Industrial Internet of Things (IIoT). The Industrial Internet of Things includes industrial applications such as robots, medical devices, and software‐defined manufacturing processes. In terms of energy conservation, routing is extremely essential. The creation of an energy effectual steering procedure leads to a substantial rise in energy consumption. To minimize network traffic and increase network life, the article presented an Industrial IoT Fuzzy Logic Energy‐Aware Routing Protocol (FLEA‐RPL), which decreases network traffic as well as improves network life. The most suitable parent for data transfer is selected based on, among other things, the routing parameters charge, residual energy, and expected transmission count. Since the load routing metric is taken into consideration during the construction of the route, the data traffic is spread across the network. This increases network’s lifetime while maintaining a high packet delivery ratio. The proposed work proposes a Multilayer Energy‐Aware Aware RPL (MCEA‐RPL) cluster for the Internet of Things to decrease network data traffic while increasing the lifetime of the network. It is split into three phases, each including the creation of network rings, intraring divisions, and intercluster routing. First and foremost, the virtual ring is created in the network. Secondly, each ring forms an identical cluster and chooses the CH node. Finally, it is responsible for the maintenance and performance of the DODAG. Data transfer from the lesser sheet to the DODAG root is known as data transfer. By using Blockchain technology, the lifetime of a network may be extended by reducing the number of identical data package transfers. This article offers Enhanced Mobility Support RPL (EM‐RPL) in Industrial IoT which enhances mobility support with blockchain and spreads system generation. It comprises two processes: a collection of the parental static node and selection of the parent moving node. The static parent selection method uses routing metrics load and residual energy to identify the parent that is most suited for data transfer. Two phases of mobile parent selection must be distinguished: data transmission and route rediscovery. The mobile node utilizes furious logic to compute the hand‐off value of the metric packet errors ratio and the signal strength indication received from the base station. If the hand‐off value exceeds the threshold limit, the DODAG route has to be changed to work correctly. The EM‐RPL thus increases the package delivery rate by reducing the amount of route interruption caused by mobility, while offering an efficient handling mechanism.

BACKGROUND: Consumer electronics or daily use home appliances are the basic necessity of every household. With the adoption of IoT in consumer electronics, this industry is set to rise exponentially. In recent times, the demand for consumer electronics rises amidst the pandemic due to a paradigm shift from in-office culture to work from home. Despite intelligent IoT devices, smart home configuration, and appliances at our disposal, the rudimentary client-server architecture fails to provide facilities like full access control of data and devices, transparency, secured communication, and synchronization between multiple devices, etc. to the users. METHODS: To overcome these limitations, Blockchain technology has been adopted in recent years, however, it has its own set of limitations in its widespread implementation. Hence, we propose a methodology using the IOTA platform, a distributed ledger technology (DLT) for secured communication between consumer electronics devices and appliances. RESULTS: The implementation provides access control, interoperability, data storage, and management with an exploratory insight towards a decentralized micro-payment use-case between Electric cars and charging stations.

In this paper, we propose a blockchain-based cold chain technology for vaccine cooling track. The COVID-19 pandemic has caused the death of millions of people. An important step towards ending the pandemic is vaccination. Vaccines must be kept under control temperature during the whole process, from fabrication to the hands of the health professionals who will immunize the population. However, there are numerous reports of vaccine loss due to temperature variations, and, currently, people getting vaccinated have no control if their vaccine was kept safe. Blockchain is a technology solution that can provide public and verifiable records. We review the World Health Organization (WHO) cool chain and Blockchain technology. Moreover, we describe current IoT temperature monitoring devices and propose Blockcoldchain to track vaccine cold chain using blockchain, thus proving an unalterable vaccine temperature history. Our experimental results using smart contracts demonstrate the system's feasibility.

Blockchain is an emerging field of study in a number of applications and domains. Especially when combine with Internet of Things (IoT) this become truly transformative, opening up new plans of action, improving engagement and revolutionizing many sectors including agriculture. IoT devices are intelligent and have high critical capabilities but low-powered and have less storage, and face many challenges when used in isolation. Maintaining the network and consuming IoT energy by means of redundant or fabricated data transfer lead to consumption of high energy and reduce the life of IoT network. Therefore, an appropriate routing scheme should be in place to ensure consistency and energy efficiency in an IoT network. This research proposes an efficient routing scheme by integrating IoT with Blockchain for distributed nodes which work in a distributed manner to use the communicating links efficiently. The proposed protocol uses smart contracts within heterogeneous IoT networks to find a route to Base Station (BS). Each node can ensure route from an IoT node to sink then base station and permits IoT devices to collaborate during transmission. The proposed routing protocol removes redundant data and blocks IoT architecture attacks and leads to lower consumption of energy and improve the life of network. The performance of this scheme is compared with our existing scheme IoT-based Agriculture and LEACH in Agriculture. Simulation results show that integrating IoT with Blockchain scheme is more efficient, uses low energy, improves throughput and enhances network lifetime.

In city areas where people are more, managing garbage is in an inappropriate way leading to multiplying of germs that can cause illness. There is a difference in how frequently they use these litter bins in various regions. Periodic checking with timing gaps does not help. They may overflow at times even earlier than expected. To avoid this and to enhance the cleaning, a smart garbage monitoring method to find when the garbage can is full is proposed in this paper. The method’s design gathers such information as well as transmits it via a network of wireless type. In this proposed method, sensing of the dustbin’s trash level is done by sensors as well as information is transmitted to the official mobile station via GSM and GPS module. Online monitoring of the garbage level at control room is made using a WiFi Module. Arduino processor interfaces the system of sensors with the network modules. This data helps contracted cleaners as well as those who provide garbage cans, promptly empty to maintain the area spick and span..

Land is an immovable unique property, its value depends on its location and to prove the ownership of the land, one must provide various legal documents that should conclusively prove it. Due to this reason a land administration and ownership title registration system should be highly secure to avoid any document forgery. The current real estate registration process take a long time to update in the centralized databases maintained in the government registration department, other departments related to the properties which creates numerous property ownership title disputes. The process of storing the land transaction records on centralized storage servers is vulnerable for the hackers to tamper the records to make duplicate, modify and forge the original transactions and also maintaining the ownership title i.e sale deed in the paper documents may lead to missing, damage of documents and also due to human errors it may contain improper, incomplete details related to the property. This paper proposes a system called the Blockchain based Secure Smart Property Registration Management System (SSPRMS) which provides a solution of tamper free, permanent storage of real estate transaction information records on the decentralized distributed public digital ledgers called hyper ledgers. The SSPRMS provides secure, instant the transfer of ownership title without the help of third party, with zero transaction cost using Smart Contracts, implemented based on PoW consensus algorithms, also providing the self-notarization mechanism, and availability of evidence for the land title from distributed databases and a Smart Property Cards (SPC) provides a mechanism for storing updated owner ship title and other details of the property in the digitized form on the digital smart cards instead of storing these information in the paper documents which eradicate the property related disputes, the fraudulent, illegal registrations of property ownership titles.

The Internet of Things paradigm enables various applications in different fields through the exponential increase of devices and sensors. Architecting systems based on Internet of Things concepts is very challenging and has focused mostly on a centralized approach. Decentralized or distributed architectures aren't straightforward concepts for IoT applications, but through the distributed ledger and Blockchain implementations that provide better identification, security and data integrity the fully distributed system architecture can become a reality. Major cloud vendors these days are using edge computing platforms to bring the cloud closer to the device, using a locally centralized system based on edge agents, which can be seen as a partially decentralized module in the full IoT cloud picture. Blockchain allows this edge IoT environment to become distributed if services or functions installed on the edge agent are used by the device to gain Blockchain capabilities. If more capable devices are deployed, then the Blockchain functionality can be embedded in the IoT and the system becomes a fully distributed peer-to-peer network.
