Virtual Network Mapping Optimization Method for Wide Coverage Power Communication Network

In order to meet the needs of wide coverage, low delay and efficient resource utilization of business communication in the new power system, satellite Internet technology is introduced to the power communication network architecture, which expands the coverage of power communication network, but increases communication delay and waste of resources. Therefore a corresponding virtual network mapping optimization method are proposed. By improving the traditional simulated annealing algorithm, this mapping method realizes the dual optimization of low delay and high resource utilization in virtual network mapping. For the algorithm improvement, genetic algorithm (GA) is proposed to find the initial solution, and a dynamic neighbor solution search range is introduced. The simulation results show that the proposed method can maximize the utilization of resources while ensuring the low delay of the wide coverage communication network, thus improving the operating efficiency and stability of the power communication system.
