Wireless broadband communication system station layout networking method and system

Abstract

The invention discloses a wireless broadband communication system station layout networking method and system, and the method comprises the steps: taking the longitude and latitude and elevation of a map as the dimensions of a search space, randomly generating an initial parent population, and setting the randomly generated initial parent population as an initial current parent population; performing fitness calculation on the current parent population to obtain an optimal chromosome with the highest fitness, and if the fitness of the optimal chromosome does not meet an iteration termination condition, performing the next step; performing mutation operation on the current parent population to generate a mutation offspring population, and performing crossover operation to generate a crossover offspring population; and performing selection operation on the parent population, the variation offspring population and the cross offspring population, selecting a plurality of chromosomes as a next-generation parent population according to a selection operation method, if an iteration termination condition is met, ending iteration to output an optimal chromosome, and decoding the optimal chromosome to obtain a final output optimal base station layout. According to the method, the complex system optimization problem is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of communication technology, and in particular relates to a method and system for site layout and networking of a wireless broadband communication system. Background technique [0002] The so-called site planning is to select the location of the base station under the premise of comprehensively considering the network coverage and other parameters to evaluate the network performance, so as to achieve the purpose of reducing the number of required base stations as much as possible and meeting the site layout requirements. In the wireless broadband communication system, the planning and selection of the station site is a key link, and it is of high use value and necessary to conduct related research. [0003] The site planning problem is essentially a large-scale, highly nonlinear combinatorial optimization problem, which is a typical NP-hard problem.
