Problems solved by technology

Therefore, when broadcasting information to send data, a large amount of data is sent at the same time, resulting in collision detection during the sending process. Once a collision occurs, the sending must be stopped and may be retransmitted several times.
As a result, it takes too long for collisions to occur in the channel, and each collision wastes channel resources, which significantly reduces signal utilization and affects the normal transmission of information

Abstract

The invention discloses a large-scale subarea positioning method based on big data transmission. The method comprises the steps of S1, sending time slot allocation through wireless signals, wherein for n time slots, 0 and n / 2+1 time slots are used for a gateway to carry out broadcasting and other time slots are used for terminals to broadcast information; S2, allocating serial numbers to all terminals, collecting all terminal serial numbers by the gateway, broadcasting the information by the terminals, collecting the information by the gateway at any time, wherein the information is broadcasted by the terminals, and analyzing the terminal serial numbers in the information; S3, carrying out load balanced hash algorithm processing on the terminal serial numbers by the gateway according to the collected terminal serial numbers, thereby obtaining balanced hash factors; S4, broadcasting the balanced hash factors and the serial number of the gateway by the gateway and requiring the terminals to send information in different time periods; S5, calculating the serial number of the gateway and the balanced hash factors by the terminals, thereby obtaining the time periods for the terminal to broadcast the information; and S6, sending the information by the terminals in the different time periods. A channel utilization rate is greatly improved, and the gateway can receive the data sent by more terminals.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a large-scale partition positioning method for data transmission. Background technique [0002] With the advent of the information age, the technology of information transmission is becoming more and more mature, and at the same time, the amount of data transmission is increasing. Therefore, when broadcasting information to send data, a large amount of data is sent at the same time, resulting in collision detection during the sending process. Once a collision occurs, the sending must be stopped and may be retransmitted several times. As a result, it takes too long for collisions to occur in the channel, and each collision wastes channel resources, which significantly reduces signal utilization and affects the normal transmission of information. Contents of the invention [0003] According to the deficiencies of the prior art, the present invention proposes a large-sc...
