Information channel and power combined self-configuration method for APs (Access Points) in wireless local area network

Abstract

An information channel and power combined self-configuration method for APs (Access Points) in wireless local area network comprises the steps as follows: the area where the APs to be configured are located is selected as a local network, and the local network is divided into a plurality of grids according to practical conditions; each AP sends out a self-configuration request to a server and simultaneously reports the position coordinate of the AP and the scanned frequency spectrum use information of the ambient environment of the AP; the server analyzes the positions and the ambient environments of the APs according to the self-configuration requests of the APs, and allocates information channels and power parameters to the APs to be configured in combination with the use conditions of AP information channels in neighbor cells under the premises of meeting the coverage rate requirement and minimizing same frequency interference, that is, first the signal energy of each grid is estimated according to a path loss empirical model to learn the network coverage condition, and then the information channel and the power parameter eventually configured for each AP is obtained through calculation based on the principle that the energy efficiency ratio is highest, and are sent to the AP to be configured. The method provided by the invention is quick and effective, guarantees the region coverage requirement, avoids same frequency interference to the maximum extent and guarantees that the energy efficiency ratio of the network is highest.

Description

technical field [0001] The present invention relates to a method for automatically allocating channel resources and power in a wireless network, to be precise, to a method for self-configuring the transmission parameters of a wireless access point AP (Access Point) in an ad hoc network, that is, in a wireless local area network Among them, a joint self-configuration method of multiple AP channel resources and power based on a grid model belongs to the technical field of mobile communication. Background technique [0002] With the development of multimedia service requirements, wireless local area network WLAN (Wireless Local Area Networks) with strong mobility, flexible networking and strong scalability is popular. Wireless local area network is a very convenient data transmission based on 802.11 standard. System, which uses radio frequency (RF) technology to replace the local area network formed by the old twisted-pair copper wires (Coaxial), which enables the wireless loca...
