Embodiment Construction

[0046] The invention provides a data processing method and device for solving the problem of signal conflict caused when multiple nodes send data to the same node at the same time.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] Such as figure 1 As shown, a data processing method provided by an embodiment of the present invention is shown, and the method includes the following steps:

[0049] S101: Obtain the first sending period corresponding to each node in the same cluster.

Abstract

The present invention provides a data processing method and device, which acquires the first sending cycle corresponding to each node in the same cluster, the first sending cycle is used to indicate the time when the first node sends data to the second node, and determines the time corresponding to each node Whether the first sending cycle overlaps, if it overlaps, adjust the sending cycle of the node whose first sending cycle overlaps, get the second sending cycle, and collect the current corresponding sending cycle of each node to form a scheduling schedule, wherein, in the scheduling schedule The sending cycles do not overlap with each other. The sending cycle includes the first sending cycle, the second sending cycle or the combination between the first sending cycle and the second sending cycle. The scheduling schedule is fed back to each node, so that each node according to The sending period corresponding to itself in the scheduling schedule sends data. It solves the problem of signal conflict caused when multiple nodes send data to the same node at the same time, and improves the data processing efficiency.

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...
