Data transmission strategy for improving wireless local area network throughput

Abstract

The invention discloses a data transmission strategy for improving wireless local area network throughput. The data transmission strategy for improving the wireless local area network throughput includes steps: (S10) setting timer time T, obtaining data transmission rates of all terminals, and accordingly figuring out average value V of the data transmission rates; (S20) setting corresponding time slices according to the data transmission rates of all the terminals; (S30) confirming corresponding quota value of data packages which can be sent in allusion to all the data transmission rates; (S40) transmitting the data packages according to the quota value of the data packages which can be sent. The data transmission strategy for improving the wireless local area network throughput ingeniously uses the time slices as measurement criterions under a multiple rate environment, sets the different time slices for the terminals of the different rates so as to regulate access time of the terminals, allocates a large number of the time slices for the terminal of the high rate, embodies advantages of the high rate, improves handling capacity of the terminal of the high rate on the premise of not improving network suddenness, and further improves the overall throughput of a network, is low in complexity and easy to implement, can not cause additional hardware costs, and has a wide application prospect.

Description

[0001] technical field [0002] The invention belongs to the technical field of communication networks, and in particular relates to a data transmission strategy for improving the throughput of a wireless local area network. Background technique [0003] In recent years, with the continuous increase in the number of mobile users and the volume of real-time multimedia data traffic, users' demands on bandwidth, performance, and coverage of wireless local area networks (WLAN) are increasing. At present, the representative standard of WLAN is IEEE 802.11, in which IEEE 802.11a / b / g / n provides multi-rate capability at the physical layer, control frames, broadcast and multicast frames are sent at the basic rate, and data frames can be transmitted according to Channel conditions select different rates for transmission. Generally, when the channel has a high signal-to-noise ratio, a high data transmission rate can be selected to send data packets. [0004] According to the tradition...

Problems solved by technology

[0005] Existing improvement measures, such as the opportunistic automatic rate protocol OAR (Opportunistic Auto Rate), allow high-rate stations to send multiple packets at a time, thereby improving the throughput of high-rate terminals, but OAR is more bursty, For example, in the case where there are only a few low-rate terminals and the others are high-rate terminals, the majority of high-rate terminals must send multiple packets at a time
