Embodiment

[0026] Such as Figure 1 to Figure 4 As shown, this embodiment provides a relay data transmission method agreed upon by data content. This embodiment only uses a star network topology as an example for illustration, and the transmission process of other network topologies is the same, so details will not be described here.

[0027] Take the data of point A to all points in the network or send the data of point A to points D1...D3 as an example. Since point A is too far away from points D1...D3, the data cannot be reached directly. Therefore, the data at point A can be directly sent to B1...B3, the data at layer B nodes can be directly sent to C1 and C2, and the data at C1 and C2 can be directly sent to D1...D3. During this process, in order to avoid the channel occupied by duplicate data caused by data return, this implementation makes the following improvements:

[0028] First, the network nodes in the star network topology are all idle and have no data to send;

[0029] W...

Abstract

The invention discloses a relay data transmission method agreed by data content, comprising the following steps: according to the network topology, the maximum relay stage number is preset, and the current relay stage number of the initial network node to be sent is set. is zero; the initial network node to send data is in the state of sending data, and broadcasts the data to several lower-level network nodes connected to the initial network node in the T time period; any network node receives data After that, the current relay level is superimposed by 1, and the network nodes that send data are juxtaposed in (N max -N i )*T time period is the rest state; judge whether the maximum relay level is greater than or equal to the current relay level, if so, set the network node to the data sending state, and use the broadcast method to transmit the data to the next level network nodes; otherwise, stop transmitting data. Through the above solution, the present invention has the advantages of simple logic and high transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of data communication transmission, in particular to a relay data transmission method agreed by data content. Background technique [0002] With the continuous development of communication technology, the nodes in the network topology are getting bigger and bigger; among them, the network topology mainly includes star structure, ring structure, bus structure, distributed structure, tree structure, mesh structure, cellular structure, etc.; in a star structure (distributed structure, tree structure, mesh structure, honeycomb structure have the same situation), such as figure 1 As shown, taking point A sending data to all points in the network as an example, point A broadcasts to B1, B2 and B3; B2 continues to broadcast to A, C1, C2 and C3 after receiving the data; similarly , nodes C1 and C2 also send data in the form of broadcast; finally reach all points; in this process, the existing data of B2 is sent bac...
