Illumination communication dynamic routing ant colony algorithm based on new probability transfer function

Abstract

The invention relates to the field of communication, in particular to an illumination communication dynamic routing ant colony algorithm based on a new probability transfer function. The algorithm is applied to a network topological graph, searches a path possibly existing between every pair of nodes in a network periodically, collects the attribute values of all routing targets on each path and records the attribute values in pheromones. The illumination communication dynamic routing ant colony algorithm based on the new probability transfer function has the advantages that the new state transfer probability function is adopted, and thus the large defect that the ant algorithm is caught into a local optimum path trap easily in path optimization is avoided; the probability transfer function is adjusted by using information weight factors in normal distribution, and thus the randomness and the blindness of the state transfer rules of the ant algorithm are reduced; the intensity of the pheromones is set by segmenting the global pheromone algorithm, and the speed of concentration increase of the pheromones on the paths where ants are concentrated excessively is relieved by introducing information amount operators based on even distribution; route routing time of carrier communication controlled by straight lamps is optimized.

Description

technical field [0001] The invention relates to the communication field, in particular to a dynamic routing ant colony algorithm for lighting communication based on a new probability transfer function. Background technique [0002] The use of power line carrier communication technology in the urban street lamp control system has advantages that other control technologies cannot match: electricity is the most basic condition of modern urban life, so without laying additional communication lines, the existing power line resources can be directly used for data transmission. Or voice signal transmission, thereby reducing communication costs. In addition, power line carrier communication equipment can be connected anywhere, which is flexible and convenient. At present, power line carrier communication technology has been widely used. Power line carrier communication can be said to be a ready-made communication channel with the widest coverage, and an intelligent network can be f...

Problems solved by technology

[0006] Previous studies have proposed some low-voltage power line carrier communication methods based on ant colony algorithm, which can effectively extend the distance of power line carrier communication, but they do not have the ability to dynamically adapt to changes in the power line environment. The convergence speed of the algorithm is slow, and it is easy to fall into the local optimization minimum
