Embodiment Construction

[0051] The design idea of ​​the channel allocation method in the wireless local area network system of the present invention is: on the basis of ensuring that each user in the system has a fair competition access channel opportunity, limit the time each user occupies the channel after obtaining the access channel opportunity, so as to control Users of different rates occupy the channel for basically the same length of time, so as to prevent low-speed users from affecting the throughput of high-speed users and improve the channel utilization throughput of the entire system.

[0052] The specific implementation manners of the channel allocation method in the wireless local area network system of the present invention will be described in detail below with reference to various drawings. See first figure 2 , this figure is the flow chart of the implementation principle of the channel allocation method in the wireless local area network system of the present invention; its main im...

Abstract

This invention discloses a channel allocation method in wireless LAN system, which comprises setting duration time to make sending user and receiving user complete data package interactive processing at least for one time; sending user obtained the chance to access in channel and receiving user continue to exchange data packages during set time and quit the channel when time exhausts, then it turns to the step that users compete the chance to access in channel. The invention can overcomes that the low-speed user affects the throughput of high-speed user, and increases channel utility throughput of whole system.

Description

technical field [0001] The present invention relates to the technical field of wireless local area network, in particular to a channel allocation method in a wireless local area network system. Background technique [0002] Wireless Local Area Network (WLAN, Wireless Local-Area Network) is a network system that follows the 802.11 protocol of the Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineers) and uses electromagnetic waves as the transmission medium. [0003] The IEEE 802.11 protocol includes two physical layer standards: the 802.11a standard and the 802.11b standard. The working frequency band of the 802.11a standard is at 2.4G, while the working frequency band of the 802.11b standard is at 5G; both the 802.11a standard and the 802.11b standard use the same Media Access Control Protocol (MAC, Media Access Control) technology. [0004] The wireless local area network system is mainly composed of an access point (AP...
