Multipath Information Announcement Algorithm for Computing Power Network based on Self-Organizing Map Network

Information announcement is a critical technology in the Computing Power Network (CPN) for monitoring real-time multi-dimensional resources of computing nodes and synchronizing them with other nodes. This paper first models the problem of minimizing the delay of information announcement as a Traveling Salesman Problem (TSP). Then, the proposed Inverse Euclidean distance Algorithm (IEDA) is utilized to determine the Euclidean space coordinates of each node based on their network delay. Finally, the proposed SOM-based Multi-route Synchronization Algorithm (SMSA) is employed to identify multiple synchronization routes for completing the Com-Net synchronization. The simulation results demonstrate that compared to traditional algorithms, the proposed method can reduce convergence time by nearly 17% and decrease the Age of Information by nearly 4%.
