Integrating Blockchain Technology for Data Collection and Analysis in Wireless Sensor Networks with an Innovative Implementation

The study integrates blockchain technology which treats each mobile database as a block. Each block will first detect its own range of sensor data. The system then concatenates the sensor data for each block through the blockchain technology. In addition to their own measurement data, these concatenated sensor data also contain all the sensor data of the previous block. Therefore, when the system completes the connection of each block, each block node stores the sensor data of the entire wireless network. Mobile database is placed in an embedded hardware module like the Raspberry Pi. This module also establishes web server at the same time. The setting of this mobile web server is based on the Web of Things (WoT) structure. The advantage of this mobile database is easy information collection, while maintaining confidentiality and security. This mobile web server can draw figures with multiple chart types on the web page whilst delivering these web pages of charts to the cloud. The mobile web server is also built on the same embedded hardware module, and even the system can be a private cloud data center. The proposed system will visualize the data uploaded by these sensors and draw the relevant chart after performing big data analysis. This web page server of the system is built on an embedded operating system so that it is easy for the system to model and visualize the corresponding graphics using the Python or JavaScript programming language.
