Blockchain technology is an information security solution that operates on a distributed ledger system. Blockchain technology has considerable potential for securing Internet of Things (IoT) low-powered devices. However, the integration of IoT and blockchain technologies raises a number of research issues. One of the most important is the energy consumption of different blockchain algorithms. Because IoT devices are typically low-powered battery-powered devices, the energy consumption of any blockchain node must be kept low. IoT end nodes are typically low-powered devices expected to survive for extended periods without battery replacement. Energy consumption of blockchain algorithms is an important consideration in any application that combines both technologies, as some blockchain algorithms are infeasible because they consume large amounts of energy, causing the IoT device to reach high temperatures and potentially damaging the hardware; they are also a possible fire hazard. In this paper, we examine the temperatures reached in devices used to process blockchain algorithms, and the energy consumption of three commonly used blockchain algorithms running on low-powered microcontrollers communicating in a wireless sensor network. We found temperatures of IoT devices and energy consumption were highly correlated with the temperatures reached. The results indicate that device temperatures reached 80 °C. This work will contribute to developing energy-efficient blockchain-based IoT sensor networks.

The widespread and growing interest in the Internet of Things (IoT) may be attributed to its usefulness in many different fields. Physical settings are probed for data, which is then transferred via linked networks. There are several hurdles to overcome when putting IoT into practice, from managing server infrastructure to coordinating the use of tiny sensors. When it comes to deploying IoT, everyone agrees that security is the biggest issue. This is due to the fact that a large number of IoT devices exist in the physical world and that many of them have constrained resources such as electricity, memory, processing power, and square footage. This research intends to analyse resource-constrained IoT devices, including RFID tags, sensors, and smart cards, and the issues involved with protecting them in such restricted circumstances. Using lightweight cryptography, the information sent between these gadgets may be secured. In order to provide a holistic picture, this research evaluates and contrasts well-known algorithms based on their implementation cost, hardware/software efficiency, and attack resistance features. We also emphasised how essential lightweight encryption is for striking a good cost-to-performance-to-security ratio. KEYWORDSIoT; a sensor device; lightweight; cryptography; block cipher; smart card; security and privacy Intelligent Power Grids: The transfer of data and control instructions between smart metres, grid equipment, and the centralised grid management system in smart grid systems is encrypted using lightweight cryptography. These low-power cryptographic systems protect data authenticity and privacy with little re-source drain. Inventory Control:To ensure the safety of data sent between GPS-enabled tracking devices and the main monitoring platform, asset tracking systems utilise lightweight encryption. In this way, pre-cious assets may be tracked in real-time, and their whereabouts can be kept secret from prying eyes.Linked Automobiles: Communications between the many Internet of Things (IoT) components in a car, such as the infotainment system, telematics, and sensors, are encrypted using lightweight cryptography in connected vehicle systems. These lightweight cryptographic methods help keep vehicle data secure and private without slowing down response times.Intelligent Farming: Soil moisture sensors, drones, and controlled irrigation systems are only a few ex-amples of the Internet of Things devices that benefit from lightweight cryptography in precision agriculture. These gadgets provide information on the state of crops and their surrounding environments, while also saving electricity and protecting the privacy of crucial agricultural records.Environmental Monitoring: Lightweight cryptography is employed in Internet of Things sensors for environmental monitoring applications in uninhabited areas like woods and seas. Even in lowpower settings, these sensors may gather information about the weather, air quality, or animals, and send it on to a central monitoring system. Management of Retai...

A smart gateway, which plays a crucial role in a smart home, generally bridges the inside and outside home networks, as well as collaboratively manages the intelligent Internet of things (IoT) devices equipped in the smart home, due to it can convert different communication protocols, gather generated data from surrounding devices, and even conduct some local data processing tasks. In this survey, we first review the whole smart home research area with a focus on a framework based on edge computing and multiple intelligent agents. Then, relying on the time‐line and different metrics including quality of experience (QoE), artificial intelligence support, software‐defined network, and so on, we divide the evolution of smart gateways into three generations. Considering recent smart gateways mainly belong to the second generation, we further investigate and classify them into two categories from another perspective of user‐awareness and data‐awareness. Afterward, we discussed the key enabling technologies and components of smart gateways, such as operating systems, wireless communication protocols, and security. At last, we explore the challenges and trends of smart gateways and point out that maximizing QoE as well as data‐awareness is the key feature of future gateways. This survey has practical significance for building a smart home system, broadly speaking, even for constructing the IoT and smart space.
