Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] The scene used in the present invention is as figure 1 As shown, there are multiple wireless access points AP, and the number of users in each wireless access point AP and the location of each user are non-uniformly distributed.

[0044] refer to figure 2 , the invention is figure 1 The specific steps for selecting the station transmission mode in the described scenario are as follows:

[0045] Step 1, obtain network information.

[0046] (1a) Each wireless access point AP periodically broadcasts the network information of its own single-hop site and two-hop site; wherein, the single-hop site refers to a site that communicates with the wireless access point AP through a single hop; The hop station refers to the station that uses the relay station to communicate with the wireless access point AP through two hops; the network information refers to the wireles...

Abstract

The invention discloses an intensive wireless local area network (WLAN) site transmission mode selecting method, and mainly aims at solving the problems of abnormal rates and uneven load distribution in the prior art. The intensive WLAN site transmission mode selecting method includes several steps, wherein a step one is that each wireless access point (AP) periodically broadcasts network information, and a site receives the network information and gathers two types of wireless AP collections; a step two is that the site calculates the largest traffic throughput of a single-hop transmission mode and a two-hop transmission mode, serial numbers of the wireless APs and a serial number of a relay site according to the acquired network information and the two types of wireless AP collections, and chooses the transmission mode which enables the traffic throughput to be largest; and a step three is that the site carries out corresponding transmission mode configuration according to the selected transmission mode, the wireless AP serial numbers and the serial number of the relay site. According to the WLAN site transmission mode selecting method, resources in the WLAN are fully utilized, the transmission mode of the site is chosen reasonably, interference in the network is reduced, the communication speed and the traffic throughput of AP edge users are improved, and a uniform load distribution is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for selecting a station transmission mode, which is suitable for a dense wireless local area network environment. Background technique [0002] Wireless Local Area Network (WLAN for short) is a network that transmits information through wireless media. Users can obtain various network services through wireless access points AP, because of its mobility, use of free frequency bands, easy installation, and low cost It is widely used in many fields such as shopping malls, temporary conferences, campus networks and security monitoring. Especially in recent years, with the rapid popularization of portable mobile smart terminals such as iPhone and Android, the rapid development of the mobile Internet market, and the emergence of various new mobile Internet application services, users increasingly expect to be able to access wireless local area network...
