Science of Security 2022 - This paper introduces the principle of public security electronic fence, analyzes the current situation and future demand of public security electronic fence application in policing, and points out the problems in equipment deployment. A public security electronic fence deployment method based on an improved artificial immunity algorithm is proposed for the above scenario, and specific solutions are given for model establishment, parameter settings, and other problems. Finally, an arithmetic analysis of the simulated scenario is carried out, and the results show that the results of using the improved immune algorithm to solve the public security electronic fence deployment problem are very reasonable and reliable, and have wide reference and promotion significance.
