Optimization method for wireless AP deployment in non-uniform environment based on fruit fly optimization

Abstract

The present invention provides a wireless AP deployment optimization method based on fruit fly optimization in a non-uniform environment, including obtaining and processing the wireless AP layout range, setting three kinds of obstacles and signal attenuation values; setting the calculation variable as the position coordinates of the wireless AP And power; initialize the fruit fly population and parameters; obtain the new position of the fruit fly individual and its distance from the origin and the judgment value of the taste concentration; substitute it into the objective function to solve the fitness; according to the fitness, select the best taste concentration value in the group the fruit flies and their positions; judge whether the taste concentration of the selected fruit flies is better than the current optimal taste concentration value; update the fruit fly position of the optimal taste concentration value, continue to iterate until the end of the iteration, and obtain the minimum total power of the wireless AP and corresponding location. By implementing the present invention, a non-uniform propagation environment is formed, and the wireless AP deployment position and power are jointly optimized, thereby solving the problem of wireless AP analysis and deployment deviation in a non-uniform environment in the prior art.

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
