Abstract

The invention relates to a wireless communication terminal, and discloses a method for avoiding wireless channel congestion on a wireless communication terminal. The method comprises the following steps of: judging whether a current wireless channel is congested or not by judging the number of data packets which are unsuccessfully transmitted in a certain time when transmitting the data packets by the wireless communication terminal in internet of things; when the channel is congested, setting an obtained random number to be time length of a timer, turning on the timer and retransmitting data after the timer times out; when the transmission is failedfails, increasing the time length of the timer to be double the conventional time length, turning on the timer and retransmitting after the time is out; and if the transmission is failedfails again, prolonging the time length of the timer by two times again on the basis of the conventional time length, turning on the timer and continuously retransmitting after the time is out until the transmission is successful or the transmission frequency exceeds the maximum retransmission frequency. Thus, an internet storm effect caused by immediate retransmission after failure of data transmission of the wireless communication terminal is avoided, the transmission requests of the wireless communication terminal are scattered, and the data transmission success rate is increased.

Description

technical field [0001] The invention relates to a wireless communication terminal, in particular to a method for avoiding wireless channel congestion on a wireless communication terminal. Background technique [0002] The concept of the Internet of Things was put forward in 1999. The goal is to build an information carrier based on the Internet and traditional telecommunication networks, so that all ordinary physical objects that can be independently addressed can realize interconnection and intercommunication. As the core of the Internet of Things data transmission system, wireless communication terminals have been widely used in various industries such as vehicles, consumer electronics, medical care, and electric power. Using the public mobile wireless network coverage provided by mobile communication operators, the wireless communication terminal builds a data interaction platform between the application terminal and the Internet of Things background: receiving background...
