Abstract

The invention provides a data processing method and device. The method includes: obtaining a first sending period corresponding to each node in the same cluster, wherein the first sending period is used for indicating the time when the first node sends data to the second node; determining whether the first sending periods corresponding to the nodes are overlapped or not; if so, adjusting the sending periods of the nodes with the overlapped first sending periods, obtaining a second transmission period, collecting a sending period currently corresponding to each node; constructing scheduling schedules, wherein the sending periods in the scheduling time table are not overlapped with each other, the sending periods comprise a first sending period, a second sending period or a combination of the first sending period and the second sending period; and feeding the scheduling time table back to each node, so as to enable each node to send data according to the sending period corresponding to the node in the scheduling time table. The problem of signal conflicts caused when multiple nodes send data to the same node at the same time is solved, and the data processing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a data processing method and device. Background technique [0002] With the advancement of science and technology, the technology of underwater environment data collection is becoming more and more mature, but there are still some problems, for example: in the underwater environment, if sensor A sends data to sensor B, and sensor C also happens to send data to sensor B Sending data caused a signal conflict, and finally caused the data sent by sensor A and sensor C to sensor B to be lost. Therefore, when the sensor has data to send, a contention-based MAC protocol is used to solve the problem of signal conflict. [0003] When the sensor needs to send data, based on the contention MAC protocol, it detects whether the channel for sending data is occupied. When it detects that the channel is occupied, it stops sending data and waits for the next cycle to re-detect whet...
