To realize the fusion management of the power distribution communication network and improve the quality of service and the management of operation and maintenance, this paper studies the multi-source and multi-communication intelligent management technology of the power distribution communication network under flat management, and establishes a resource mapping model of hybrid networks based on particle swarm algorithms. The model can map WMN and PLC to the same physical network. Their advantages are brought into full play with different tasks assigned. Besides, more sub-carriers are adopted to improve service throughput. The simulation of the newly established model and its comparison with the genetic algorithm demonstrates the superiority of the proposed algorithm.
