Abstract
Advances in communication technology and embedded systems have ushered in a new paradigm known as the Internet of Things (IoT), Currently, IoT is one of the most significant trends in industrial transformation and beyond 5G networks. Blockchain techniques have become essential features for applications, primarily due to their potential in ensuring security and privacy. Consequently, there is a growing interest in utilizing Blockchain for these purposes in modern IoT devices. In this paper, we introduce the Proof of Stake (PoS) algorithm as a mean to achieve consensus among nodes for anomaly data detection. The Blockchain model in IoT encompasses four elements: <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Hash_{prev}, Hash_{next}$</tex> , Transactions, and Randomness. During the election process in Blockchain, the sensor nodes consider two parameters: firstly, node identification based on the Internet Protocol (IP), and second, the Uniform Resource Name (URN). Our findings show that the proposed method outperforms existing schemes in terms of the Quality of Experience (QoE) metrics, such as the Processing Time Reduction Ratio (PTRR), Resource Gain (RG), and latency.
