Abstract

The invention discloses a genetic algorithm-based power line carrier communication routing adaptive optimization method. First, a load risk model for information transmission between different communication nodes is built, partial and global business failure risks under different loads are quantified, and the impact of number of hops and load amount during information transmission on a business load risk is evaluated; then on the basis of evaluation, a routing table of communication nodes is designed and a business load strength on a communication path is analyzed by using a genetic algorithm; and finally, on the basis of a risk evaluation model, routing featuring minimum business risk and maximum load balance is selected through dynamic, iterative optimization. The method has the beneficial effects that the number of hops for signal transmission between different nodes and communication nodes for forwarding and signal amplification are optimized through reasonable routing design, and preferred routing is built so as 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, relates 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-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 network...
