Cloud-Enabled Blockchain and IoT-Based Assisted Living System in 6G Networks: Enhancing Quality of Life and Privacy

Owing to emerging disruptive technologies, the Internet of Things (IoT) plays an important role in innovative living domains, such as elderly and disabled healthcare service and home security and safety monitoring, and computerization control service. The IoT can improve inhabitants' quality of life and users of smart ambient assisted living (AAL) environments. The sixth (6G) networks will enable a completely linked world with terrestrial wireless communications. Blockchain-based approaches offer decentralized privacy and security and, yet they include vital delay, computational, and energy overhead that are inappropriate for most resource-reserved IoT devices. Hence, in this study, a Blockchain and IoT-based Assisted Living System (BIoT-ALS) has been proposed using 6G communication. The nodes in our proposed paradigm use smart contracts to specify norms of interaction while working together to provide storage and computing resources. Our suggested approach has encouraged confidence-free interaction and boosted user privacy by the blockchain approach. The purpose of this paper is to explain the sensor layer, a distributed signal processing system in vast, physically connected, wirelessly networked, and energy-restricted networks of sensor items. A comprehensive series of experimental tests have been conducted, showing each sensor type's accuracy and probable usage. The numerical results show that the suggested BIoT-ALS model improves the performance ratio of 99.1%, accuracy ratio of 98.8%, reliability ratio of 94.8%, an efficiency ratio of 93.6%, the throughput rate of 97.6%, and reduces the network delay of 19.2%, latency ratio 10.2%, and execution time of 20.4% compared to other popular models.
