Abstract

The invention discloses a genetic algorithm-based self-adaptive optimization method for power line carrier communication routing. First, by constructing a load risk model during information transmission between different communication nodes, quantify the local and global business failure risks under different loads, and evaluate the degree of impact of the number of hops and load during information transmission on business load risk; secondly, evaluate Based on the genetic algorithm, the routing table of the communication node is designed, and the business load intensity on the communication path is analyzed; finally, on the basis of the risk assessment model, the routing selection with the least business risk and the maximum load balance is selected through dynamic iteration. Beneficial effects of the present invention: Optimizing the number of hops to be selected for signal transmission between different nodes and communication nodes for relay and signal amplification through reasonable routing design, constructing an optimal routing selection to improve the reliability and quality of remote signal transmission.

Description

technical field [0001] The present invention relates to the technical field of power line carrier communication, in particular, to a genetic algorithm-based adaptive optimization method for power line carrier communication routing. Background technique [0002] At present, medium and low voltage power line carrier communication transmission mainly adopts OFDM technology, and realizes multi-frequency band and multi-period signal transmission through time division multiplexing and frequency division multiplexing. Based on the problems of large randomness and instability, fast attenuation of signal transmission, and susceptibility to electromagnetic interference during medium and low voltage power line carrier communication transmission, the general related research and design are mainly biased or focused on OFDM system channel optimization for power line carrier communication. Transmit power control, spectrum management, etc. Because the power line carrier communication netwo...
