Data transmission control method, communication system and machine-readable storage medium

Abstract

The invention discloses a data transmission control method, a communication system and a machine-readable storage medium, comprising: step 1, calculating the data sending time of k terminal nodes of the ZigBee network by the following formula, wherein T is a preset time Set the period value, k is the terminal node number; t Endk is the original sending time of the terminal; n is the number of terminal nodes, and n is greater than or equal to 2; step 2, starting from the second terminal node, judge whether the sending time interval between each subsequent terminal node and all the previous terminal nodes is greater than or equal to preset time; in the case that the sending time interval between each subsequent terminal node and all the terminal nodes in the pre-order is greater than the first preset time, control the terminal node to perform sending at the original sending time; step 3, repeat step 2 to obtain Send time for all end nodes. The invention can avoid the problem that the packet loss rate is too high during data transmission, and avoid the packet loss rate while avoiding congestion.

Description

technical field [0001] The present invention relates to the field of network transmission, and in particular, to a data transmission control method, a communication system and a machine-readable storage medium. Background technique [0002] In the point-to-point communication of ZigBee, if the terminal node transmits data, the CSMA-CA mechanism is generally used to deal with the problem of data congestion, but the above method cannot solve the data packet loss rate. [0003] How to design a data transmission control method for ZigBee network terminal nodes to avoid high packet loss rate during data transmission has become an urgent problem to be solved at this stage. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a data transmission control method, a communication system and a machine-readable storage medium, the data transmission control method can avoid the problem of high packet loss rate during data transmission, avoid congestion a...
