Embodiment

[0023] like figure 1 As shown, the processing flow of this example is, when the wireless data access point receives the data transmitted by the upper layer protocol, the statistical module firstly counts the data of each workstation, and obtains the transmission rate, and then uses the mobile index through the data processing module The smoothing algorithm estimates the media occupation time, and then the enqueuing module puts the data into different queues according to the calculated media occupation time, and finally the scheduling module sets different AIFS values, CW ranges and TXOPs according to the priorities of different queues size, and then send the data through the wireless transceiver.

[0024] The specific implementation methods and principles are:

[0025] As stipulated by the 802.11 standard, in an infrastructure network, all data communication must pass through an access point. Therefore, it is easy to obtain the data volume of each client in the access point,...

Abstract

The invention relates to the wireless data transmission technology, in particular to an intelligent allocation method for a wireless flow. The method has the main technical schemes of: according to an adaptation speed and a data amount of a wireless client end, obtaining the occupied time of a wireless medium, by dividing the time of an access point into time pieces T, and by utilizing a mobile index smoothing method, estimating the occupied time of the medium of the wireless client end in the next time piece T; and flexibly applying a size of a competition window and an arbitration inter-frame space (AIFS) in the criterion of 802.11e to set different priority levels for various queues, and thus realizing the intelligent allocation of the wireless flow. The method has the beneficial effects that a wireless network can be enabled to reduce affects of a client end with a low speed and poor signal quality on the client end with the high adaptation speed and good signal quality in the situation of a high load, the experience of wireless Internet surfing of the client end with the high adaptation speed and good signal quality is promoted, and thus the throughput capacity of an overall wireless network is improved. The method is particularly suitable for the allocation method for the wireless data flow.

Description

technical field [0001] The invention relates to wireless data transmission technology, in particular to an intelligent distribution method of wireless traffic. Background technique [0002] With the development of smart phones and tablet PCs, traditional wired connection methods can no longer meet the challenges brought about by the mobile lifestyle. However, with the increasing number of mobile devices, the performance of 802.11 networks is also challenged. The IEEE group is also actively improving the 802.11 standard, from 11b's maximum throughput of 11Mbps to 11g's 54Mbps, and then to the existing 11n's maximum rate of 300Mbps, its performance has been greatly improved. However, the improvement of wireless throughput cannot fundamentally solve the problem of user experience of wireless workstations. The main problems are slow Internet access, frequent disconnections, etc., especially in the case of a large number of wireless workstations, such as in airports. , parks, t...
