Wireless AP deployment optimization method based on fruit fly optimization in non-uniform environment

Abstract

The invention provides a wireless AP deployment optimization method based on fruit fly optimization in a non-uniform environment, and the method comprises the steps: obtaining a wireless AP deploymentrange, processing the wireless AP deployment range, and setting three types of obstacles and signal attenuation values; setting calculation variables as position coordinates and power of the wirelessAP; initializing a drosophila population and parameters; acquiring a new position of the drosophila melanogaster individual, a distance from the new position to an original point and a taste concentration judgment value; substituting into a target function to solve the fitness; according to the fitness, selecting the drosophila melanogaster with the optimal taste concentration value and the position of the drosophila melanogaster; judging whether the taste concentration of the selected drosophila melanogaster is superior to the current optimal taste concentration value or not; and updating the position of the fruit fly with the optimal taste concentration value, and continuing iteration until the iteration is finished to obtain the minimum total power of the wireless AP and the corresponding position. By implementing the method and the device, a non-uniform propagation environment is formed, and the wireless AP deployment position and the power are jointly optimized, so that the problems of wireless AP analysis and deployment deviation in a non-uniform environment in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of wireless APs, in particular to a wireless AP deployment optimization method based on fruit fly optimized non-uniform environment. Background technique [0002] In recent years, with the rapid development of the mobile Internet and the diversification of learning and office locations, the traditional network cable access to the Internet has become more and more inconvenient, especially in public office places with high personnel mobility. protrude. A large number of wireless networks are deployed in densely populated places such as campuses, factories, and companies, and various wireless access points can be seen everywhere in our daily life. Wireless AP has basic functions such as relay, bridging, and master-slave mode control, but its working range is limited, and APs placed without reasonable arrangements will cause a series of problems. For example, if the distribution locations are too loose, signal...

Problems solved by technology

[0004] However, in the above-mentioned network topology optimization method, because the models used are all uniform models, and each node has the same coverage radius, there are deviations in the analysis and deployment of wireless APs in a non-uniform environment.

The main reason for the above-mentioned deviations in wireless AP analysis and deployment is that in the actual wireless signal propagation process, the attenuation of the signal is not linearly related to the propagation distance, and when the propagation is blocked by obstacles, the signal will have a relatively obvious attenuation
