Embodiment 1

[0033] figure 1 It is a flow chart of the broadcast message transmission method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of selective flooding of broadcast messages, and the method can be executed by the broadcast message transmission device provided by the embodiment of the present invention. , the device can be implemented in the form of software and / or hardware, and generally can be integrated in the communication node equipment.

[0034] like figure 1 As shown, the broadcast message transmission method provided in this embodiment includes:

[0035] S110. When there is a broadcast message that needs to be broadcast, establish an initial transmission association relationship set according to the connection relationship between each neighbor node; wherein, the initial transmission association relationship set includes each transmission association relationship when the broadcast message is first broadcast in the wireless ne...

Embodiment 2

[0102] Figure 8 It is a flow chart of a broadcast message transmission method provided by Embodiment 2 of the present invention. On the basis of the foregoing embodiments, the broadcast message transmission method provided by this embodiment further includes:

[0103] When it is determined that the broadcast message needs to be retransmitted, a retransmission association relationship set is established according to the node connection relationship corresponding to each neighbor node that has not responded successfully; wherein, the retransmission association relationship set includes each item of the retransmission of the broadcast message in the wireless network Transmission association relationship, and each neighbor node that does not respond successfully in each transmission association relationship is covered only once;

[0104] The retransmission association relationship set is carried in the frame header of the broadcast message for transmission, so as to control the ...

Embodiment 3

[0143] Figure 11 It is a flow chart of a broadcast message transmission method provided by Embodiment 3 of the present invention. This embodiment is embodied on the basis of the foregoing embodiments, wherein the network topology is specified as determining that only one-hop nodes and two-hop nodes exist according to the connectivity relationship between neighboring nodes.

[0144] Correspondingly, according to the connectivity relationship between each neighbor node, determine all one-hop nodes and establish the transmission association relationship between adjacent two-hop nodes in order of the number of node hops from small to large, which can be specifically:

[0145] Determine all one-hop nodes; select a one-hop node as the current processing one-hop node in order according to the order of one-hop node connectivity from large to small; establish the current processing one-hop node connected to it and not covered by the transmission association relationship The transmiss...

Abstract

The embodiment of the invention discloses a broadcast message transmission method and device, equipment and a medium. The method comprises the following steps: when a broadcast message needs to be broadcasted, establishing an initial transmission association relationship set according to a connection relationship among neighbor nodes, wherein the initial transmission association relationship set comprises each transmission association relationship when the broadcast message is broadcasted for the first time in a wireless network, and each neighbor node in each transmission association relationship is only covered once; and carrying the initial transmission association relationship set in a frame header of the broadcast message for transmission so as to control a neighbor node receiving the broadcast message to determine a processing strategy of the broadcast message according to the matched transmission association relationship. According to the technical scheme, selective flooding of the broadcast message is realized, unnecessary broadcast flooding is avoided, and thus the network resource overhead is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a broadcast message transmission method, device, equipment, and medium. Background technique [0002] Broadcasting refers to sending messages to all connected nodes during network transmission. Flooding is a traffic passing technique used by switches and bridges to send traffic received on an interface to all interfaces except that interface. At present, broadcast messages are usually processed by flooding, but when the network topology is complex, for example, when some nodes present a mesh topology, this method will undoubtedly increase network resource overhead. Contents of the invention [0003] Embodiments of the present invention provide a broadcast message transmission method, device, equipment and medium, so as to reduce unnecessary broadcast flooding. [0004] In a first aspect, an embodiment of the present invention provides a bro...
