Employing Blockchain Technology to Strengthen Security of Wireless Sensor Networks

Abstract

The proposed approach uses blockchain-based technology to strengthen the data security of wireless sensor networks (WSNs). This paper integrates blockchain-based technology with data transfer to establish an extremely secure WSNs structure. The present wireless network is built on the architecture of the Internet of Things (IoT) and employs a blockchain-based method to make the reliability of data transmission strong. In this proposed research, many small-area wireless sensor networks establish the entire WSNs structure, and every small-area wireless sensor network has a primary data collection node called a "mobile database." The "mobile database" node of this study uses embedded microcontrollers with an operating system, such as Raspberry Pi and Arduino Yun. This block contains the sensor data collected by itself and the hash value of the previous block. Then the hash value of its own block, which is also part of the hash calculation of the next block, was calculated through the mining calculation program. Any block in the proposed method includes the encrypted hash-value of the previous block, the current timestamp, and the transaction data. In our research content, the transaction data is represented as wireless network sensing data. Basically, the system employs the hash function for calculation using the Merkeltree algorithm. Such programming makes the block with blockchain-based technology difficult to tamper with content. This study approach revises the blockchain-based transaction ledger to become a sensor data record. Therefore, the proposed system gathers and analyzes sensor data for more reliability in the wireless sensing network structure. Furthermore, the innovative system with blockchain-based technology can treat a private cloud-end. This paper also carries on to visualize the uploaded sensing data by the sensors and draws corresponding charts based on big data analysis. The wireless network architecture proposed in this paper is built on embedded devices, making it easy for the system to build a web server. Using Python or JavaScript programming language in the web environment is relatively more convenient for data visualization and data analysis.Finally, this study uses traditional methods and innovative methods to compare data transmission. When the system uses innovative methods with blockchain-based technology, it is almost impossible for any operator to tamper with the data transmitted by the sensor.

A Blockchain System for TDMA-Based Tactical Wireless Networks With Constrained Resources

“…Hsiao and Sung integrated blockchain technology into the transmission of sensor data and, in this way, were able to enhance transmission reliability [16]. However, some issues have come out of using this kind of approach such as transmission delays caused by cryptographic processing and low transmission efficiency as the amount of data transmitted increases.…”

Implementation of explainable artificial intelligence in commercial communication systems using micro systems

“…Meanwhile the data that is sensed using MEMS should be designed in an appropriate manner with differential capacitive sensors. In both case studies, 11,12 it is perceived that sensitivity of MEMS will increase due to dynamic characteristics in the construction phase. To reduce the sensitivity constraint geometrical parameters are designed inside the sensing elements 13 thus giving raise to input parameters to resolve in outdoor environments.…”

Blockchain in sustainable supply chain management: an application of the analytical hierarchical process (AHP) methodology

“…In the foreseeable future, robots and components in manufacturing are unlikely to require human control to interact. These enhancements make it easy to build and join multi-person interactive and collaborative development networks (Lezoche et al, 2020;Hsiao and Sung, 2021). Also, virtual reality (VR) and augmented reality (AR), both of which enable real-time meetings and immersive data sharing in dynamic settings, are promising collaboration techniques between blockchain and supply chain management, which could improve product quality and consistency (De Souza Cardoso et al, 2019).…”
