Trusted Power Load Management Communication Framework Using Topology Clustering and Blockchain Authentication

This paper proposes a novel communication framework for a new type of power load management system, utilizing a geographic clustering approach based on the K-means algorithm to optimize network topology. Each cluster of communication nodes forms a subnet, with the cluster center serving as a routing node. Leveraging blockchain principles, each subnet is structured as a circular blockchain, starting with the routing node as the genesis block. This node initializes communication with a timestamp and computes the hash of the block, passing it to the next node. Subsequent nodes add their data and timestamps to the previous hash, computing new hashes and continuing the chain. The last node in the subnet links back to the routing node, forming a closed loop, which enables the routing node to validate the integrity of the entire subnet’s data. The same validation mechanism is extended between the routing nodes and the main station of the power load management system, ensuring robust and trustworthy communication across the network. This dual verification mechanism enhances the reliability and security of data transmission within the power load management system.
