Problems solved by technology

[0002] The existing available bandwidth detection method uses a model-based control algorithm. Although it can accurately detect network fluctuations, the amount of calculation is large. When the bandwidth is not occupied for a long time, it is still in the state of high-frequency detection in the background, resulting in increased energy consumption. Therefore, we propose an adaptive real-time detection method for wireless network available bandwidth

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0024] refer to figure 1 , a kind of technical solution that the present invention proposes: wireless network available bandwidth self-adaptive real-time detection method, comprises at least one wireless router, at least one mobile receiving end, and specific detection method is as follows:

[0025] A) When the amount of data sent by the wireless router is greater than 100Kb / s, use the second frequency to detect the bandwidth. The second frequency is a decreasing formula opposite to the increasing formula. When the amount of data sent by the wireless router is greater than 100Kb / s As the time increases, the interval of the second frequency detection decreases accordi...

Abstract

The invention discloses a wireless network available bandwidth self-adaptive real-time detection method, which is characterized by comprising at least one wireless router and at least one mobile receiving end, and specifically comprises the following steps: A) when the data volume sent by the wireless router is greater than 100Kb / s, detecting the bandwidth by adopting a second frequency; b) enabling the wireless router to calculate the packet loss rate according to the information in the RTCP feedback packet; c) smoothing the packet loss rate lambda through a filter, wherein lambda = a lambda+ (1-a) b; d) when the data volume sent by the wireless router is less than 100Kb / s, detecting the bandwidth by adopting a first frequency. By designing the present application, the occupation of thebandwidth is detected by adopting two different frequencies; calculation is carried out by adopting an increasing formula and a decreasing formula, the corresponding detection frequency is decreased along with the increase of the idle time of the bandwidth, and otherwise, the corresponding detection frequency is increased along with the increase of the occupied time of the bandwidth, so that the occupation of resources can be reduced and the energy consumption is reduced while the accurate detection of the bandwidth is ensured.

Description

technical field [0001] The invention belongs to the technical field of bandwidth detection, and in particular relates to a method for self-adaptive real-time detection of available bandwidth of a wireless network. Background technique [0002] The existing available bandwidth detection method uses a model-based control algorithm. Although it can accurately detect network fluctuations, the amount of calculation is large. When the bandwidth is not occupied for a long time, it is still in the state of high-frequency detection in the background, resulting in increased energy consumption. Therefore, we propose an adaptive real-time detection method for wireless network available bandwidth. Contents of the invention [0003] The purpose of the present invention is to provide a wireless network available bandwidth adaptive real-time detection method to solve the problems raised in the background technology above. [0004] In order to achieve the above object, the present inventi...
