Internet of Things (IoT) applications and services have become increasingly prevalent due to the fast evolution of wireless sensor networks, smart devices, and conventional information and ...communication technology. The data processed by IoT systems is enormous. This information may be extremely delicate because it relates to private matters such as health, finances, and whereabouts. Therefore, strong access control is essential for IoT's granular security management. Several solutions have been proposed to handle security for the Internet of Things. Although blockchain-based approaches are being developed for IoT access control, they are very briefly referenced. In this article, we look at the growing interest in and need for IoT access control systems that are built on the blockchain. In this article, we examine the pros and cons of using blockchain technology to get access to the Internet of Things, including distributed systems, safe data management, and trustless information exchange. Finally, we highlight several promising areas for further study on the merging of blockchain technology with Internet of Things networks.
These underwater Acoustic Sensor Networks (UWSNs) present unique challenges due to the harsh and dynamic underwater environment, making efficient communication protocols essential for their ...operation. This paper introduces an innovative Energy Efficient Clustering Routing Protocol (EECRP) specifically designed for UWSNs, leveraging the advancements of 6G technology. EECRP employs a distributed clustering mechanism and energy-efficient routing strategy to optimize energy consumption, prolong network lifetime, and enhance communication reliability. The protocol integrates with 6G technologies, such as terahertz communication and quantum communication security, to further enhance performance and security in UWSNs. Through simulation and comparative analysis, EECRP demonstrates superior performance compared to existing routing protocols in terms of energy efficiency, throughput, and scalability. EECRP's contributions lie in its novel approach to routing in UWSNs, emphasizing energy efficiency, sustainability, and integration with advanced technologies. This research paves the way for the adoption and deployment of EECRP in various underwater applications, facilitating scientific research, environmental monitoring, and technological innovation in underwater communication systems.
There is a limitless supply of useful information and services made available by IoT devices connected to the internet. The Internet of Things (IoT) refers to the vast network of interconnected ...devices seen in a smart city. The scattered and dynamic natures of entities such as sensing, actuating devices, humans, and computing resources make it challenging to design applications in such large-scale IoT systems, despite the promise nature of the new breed of data and resources. In this research study, the proposed approach takes a coordinated look at the process of creating Internet of Things apps for use in Smart Cities. The proposed approach demonstrates the need for a distributed coordination model capable of monitoring such a vast number of independently operating parts while constructing Smart City IoT applications. Preprocessing, feature selection, and model performance evaluation are all used in the suggested method. Normalization and standardization are used during preprocessing. It uses entropy HOA for feature selection. The model's effectiveness is measured with Deep Residual Bi-LSTM. When compared to BiLSTM and Residual LSTM, two existing approaches, the suggested methodology performs admirably.
