Power Data Sharing and Secure Interaction System Technology Based on k-Nearest Neighbor

Abstract

With the increasing demand for electricity, efficient power data transmission is a reliable guarantee for the safe operation of the power grid. In order to effectively realize the fast and reliable transmission of data in the shared security interaction system, the k-Nearest Neighbor will be based on the nodes carrying information and use the opportunity to meet with neighboring nodes to accelerate data transmission. Simulation test results show that when the number of nodes is 600, the maximum delay time of blockchain technology is 24.2 ms, while the maximum delay time of the k-Nearest Neighbor is only 21.9 ms, which is 9.50% lower than that of blockchain technology. When the number of neighboring nodes is 9, the shared interactive system load reaches a minimum of 51.6%, which is 41.03% lower than the number of neighboring nodes 1. Therefore, it is recommended that the number of neighboring nodes of the shared interactive system should be controlled at 9 to ensure the efficiency of power data transmission speed. And the total packet loss of blockchain technology is 87.2 MB, while the packet loss of the data transmission mechanism based on the k-Nearest Neighbor is 5.3 MB, and the corresponding packet loss rates are 43.6% and 2.6%, respectively, which is a 41% saving over blockchain technology. In summary, the shared security interaction system based on the k-Nearest Neighbor can effectively improve the transmission and interaction efficiency of electric power data with the advantages of fast transmission speed and short delay time.
