Abstract

The invention discloses a method for calculating a wireless channel utilization rate based on a data packet retransmission rate. The method comprises the following steps: 1, carrying out long-time measurement on a real large-scale wireless local area network, and carrying out field acquisition and data cleaning on measurement data to obtain an operation data set of a wireless access point and a wireless terminal; 2, carrying out statistical analysis on the operation data set to obtain a corresponding relation between a retransmission rate of a received data packet and a channel utilization rate; 3, drawing a scatter diagram according to the corresponding relationship to obtain a fitting formula, and calculating the channel utilization rate by receiving the retransmission rate of the data packet.

Description

technical field [0001] The invention relates to the field of wireless local area network measurement, in particular to a method for calculating wireless channel utilization rate based on data packet retransmission rate. Background technique [0002] With the continuous reform and development of wireless local area network technology, mobile terminal equipment and mobile applications, WLAN is no longer a supplement to wired networks, but has become the main network access method. Due to the ever-increasing demand for WLAN, the construction of campus WLAN is gradually developing to large-scale or even ultra-large-scale, and large-scale wireless LAN measurement technology has also become a research hotspot. The wireless LAN is still an IP network, and the performance indicators measured by the wired network are basically applicable to the wireless LAN. However, since the wireless LAN adopts a wireless connection mode, the measurement methods for the same performance indicators ...
