Method for solving packet loss of real-time application in WiFi based on router

Abstract

The invention discloses a method for solving packet loss of a real-time application in WiFi based on a router. The method comprises the steps of: detecting the connection rate of a link, checking packet sending parameters, and determining message retransmission or retransmission suspension. Mainly for applications having relatively high real-time requirements, the method relieves the packet loss problem of applications very sensitive on packet loss, such as real-time battle mobile phone games, audios and videos, in a WiFi environment. A software development kit is loaded on the router, and used for monitoring transceiving of messages; when packet loss happens or the fact that packet loss will happen is foreknew, related messages are retransmitted; therefore, the packet loss rate is reduced; simultaneously, when packet loss of an application is found, rapid retransmission can be carried out, so that normal operation of a service is ensured; and thus, the packet loss phenomenon due to relatively high time delay of a communication message between a mobile phone and the router because of interference and network congestion of communication of all kinds of applications in WiFi can be avoided.

Description

technical field [0001] The invention relates to the technical field of real-time connection between a router and a mobile phone, in particular to a router-based method for solving packet loss under real-time application WiFi. Background technique [0002] Since more and more devices use the WiFi protocol for communication, and WiFi itself uses public frequency bands for communication, it is difficult to guarantee the communication quality of various applications under WiFi. All kinds of interference and network congestion lead to relatively large delays and packet loss in the communication between the mobile phone and the router. [0003] There are many reasons for the large delay and packet loss under WIFI, mainly including the following categories: 1. The signal strength is weak, which leads to the inability to correctly analyze wireless packets. 2. The signal-to-noise ratio is not up to the standard, so the wireless packets cannot be parsed. 3. The channel is congested,...

All kinds of interference and network congestion lead to a relatively large delay and packet loss in the communication between the mobile phone and the router.

[0003] There are many reasons for the large delay and packet loss under WIFI, mainly including the following categories: 1. The signal strength is weak, which makes it impossible to correctly analyze wireless packets

2. The signal-to-noise ratio is not up to standard, resulting in the inability to parse wireless packets

3. The channel is congested, resulting in no opportunity for the message to be sent
