Self-adapted distributed power control method

Abstract

The invention relates to a self-adaptive distributed power control method in the telecommunication technology field. The method comprises the steps: first, the initialization to parameters of a wireless customer station and a wireless access point; second, the selection of the wireless access point, and establishment of the connection; third, the calculation of the anticipated throughput of the wireless access point; fourth, the startup of a timer with one-week triggering cycle; fifth, the actual throughput of the wireless access point within one cycle; sixth, the comparison of the actual throughput with the anticipated throughput of the wireless access point one cycle later to confirm whether to increase or reduce the transmission powder of the wireless access point; seventh, the regulated transmission powder value of each wireless access point is written on a configuration file, facilitating the read of the next iteration; eighth, the new iteration. With the fast convergence speed, the invention enhances the network resource utilization efficiency and decreases the calculation complexity.

Description

technical field The present invention relates to a method in the technical field of telecommunications, in particular to an adaptive distributed power control method. Background technique IEEE 802.11, launched by IEEE in 1997, works in the 2.4GHz frequency band and is a popular standard for wireless local area networks. With the increase of wireless access points (AP) and the density of WLAN, limited wireless resources and their reasonable allocation and multiplexing become hot issues in WLAN research. The power control is one of the important branches. Most of the previous studies are based on cellular networks, and the uplink terminal implements power control by including the transmission power requirements in the output data. In IEEE 802.11 WLAN, data is transmitted in a single shared channel. The structural model of the wireless local area network includes the basic basic service set and the independent basic service set. The basic basic service set includes wireless...

Problems solved by technology

Only when all the wireless access points and wireless client stations of the network use the improved media access control protocol, this method can be applied; secondly, the method of adjusting the transmission power is for each data packet, in the case of high data rate case, it will inevitably affect the performance of the system
