Research On Communication Base Station Planning Method Based On Genetic Algorithm

In recent years,China's information and communication technology has developed very rapidly,among which information and communication infrastructure is the key content to enhance national strength,safeguard national security and enrich people's life.Especially with the development and promotion of national 5G technology,5G base station construction is an important work content of future communication infrastructure.Therefore,the site selection of base station will become an important work of base station construction.China tower company was formally established in September 2014.It was jointly invested and established by China mobile,China unicom and China telecom.In the communication infrastructure construction,tower and other infrastructure construction in the repeated construction problem has been effectively improved,so that the investment efficiency can be improved,improve the sharing of resources,avoid bad competition between operators and repeated investment.The construction and maintenance of communication infrastructure is the main business of tower work.Effective site selection can not only improve the investment efficiency,but also reduce the cost of base station construction and maintenance.Therefore,it is of practical significance to study the site selection of base stations.Based on the analysis of the principles and objectives of the tower company,this paper extracts several factors that influence the site selection of the base station.In the process of site selection,many influencing factors need to be considered.In this paper,the final three influencing factors are taken as the objective function of site selection: the maximum coverage rate,the minimum construction cost and the best communication quality.Genetic algorithm is used to analyze the optimal solution in the simulation space to find the optimal method of station construction.Simulation software is used to simulate the coverage of base station to prove the rationality of the site selection scheme.It mainly includes three aspects:The first is the analysis of the construction principles and influencing factors of the tower company.In this part of the study,the construction principles of tower company and the business needs of the target area are analyzed and studied,the principles and difficulties of the site selection problem of the base station and the site selection influencing factors are analyzed,and the cost,coverage rate and communication quality are finally determined as the optimization objectives.Secondly,genetic algorithm is used to study and analyze the site optimization.In this part of the study,the mathematical modeling of the site selection of the base station,determine the cost and coverage rate,communication quality three optimization objective functions,and the site selection of the base station for the code,the use of genetic algorithm to optimize the site selection of the base station,through the simulation in matlab comparison,determine the optimization role of the genetic algorithm.The third is to select the specific area of liaodong bay new area of panjin city for example simulation.Through simulation software simulation,it can be found that genetic algorithm can make this area in the premise of fewer base stations,coverage will be improved.
