Embodiment Construction

[0032] Wireless local area network is a new data communication system that is different from the traditional wired connection. In WLAN, Basic Service Set (BSS) is the basic component of WLAN. Within a specific coverage area, stations with certain associations form a BSS. According to the networking form, BSS can be divided into infrastructure networks with access points (APs) (see figure 1 Basic service sets 200 and 300 shown) and ad hoc networks without APs (see figure 1 The basic service set 100 is shown).

[0033] An ad hoc network includes multiple sites 130 belonging to a coverage area, and the sites 130 communicate directly with each other.

[0034] In an infrastructure network with APs, each station 130 is associated with an AP dedicated to managing the BSS (120, 130 in the figure). The AP here is actually a kind of station, which can be called a central station. The BSS built around the AP is called the BSS with infrastructure (ie 200, 300 in the figure). BSSs wi...

Abstract

The invention discloses a contention window adjusting method and device. The contention window adjusting method includes that an access point initializes a first parameter, the first initialized parameter is issued via beacons, the first parameter is power exponent of the minimum contention window, the first parameter meets the formula CWmin=2ECWmin-1, the ECWmin is the first parameter, and the CWmin is the minimum contention window; the access point acquires network quality parameters within a preset beacon period and adjusts the first parameter when the network quality parameters exceed the threshold value range, so that the minimum contention window meets data transmission requirements. By the contention window adjusting method, the access point is capable of intensively controlling adjustment of the contention window, network control is reinforced and easy to implement.

Description

technical field [0001] The invention relates to the field of wireless local area networks, in particular to a method and equipment for adjusting a contention window. Background technique [0002] In today's era, wireless local area network (Wireless Local Area Network, WLAN) spreads in many corners of the world, and the vigorous development of WLAN makes people's communication life more colorful. With the diversification of communication services, especially the continuous development of multimedia services, the number of intelligent terminals has increased sharply, and WLAN is facing enormous pressure. Therefore, how to maximize the admission capacity of the WLAN and the network performance of the WLAN has become an important research topic in domestic research. [0003] The IEEE802.11n Media Access Control layer (MAC) supports shared access to the wireless network through a technology called Carrier Sense Multiple Access with Collision Avoidance (CSMA / CA), which is used i...
