Abstract

The invention provides a data transmission method and device, a readable storage medium and node equipment. The method comprises the steps of: acquiring a current position of a source node, and determining a map partition where the source node is located in a plurality of map partitions which are divided in advance according to the current position of the source node; establishing a node connection table according to the map partition where the source node is currently located and currently connected neighbor nodes; determining saturated nodes in the node connection table, and then determining a proportion of saturated nodes in the node connection table; and comparing the proportion of the saturated nodes in the node connection table with a second threshold value, and if the proportion is greater than the second threshold value, starting to detect the data size of to-be-forwarded data packets, and forwarding the to-be-forwarded data packets with the data size smaller than a third threshold value and filtering out the to-be-forwarded data packets with the data size not smaller than the third threshold value according to a detection result. According to the data transmission method and device, the condition of node data distribution congestion in an opportunity network can be reduced.

Description

technical field

[0001] The present invention relates to the technical field of opportunistic network communication, in particular to a data transmission method and device, a readable storage medium, and a node device. Background technique

[0002] Opportunistic network is a kind of wireless ad hoc network, which is different from traditional communication network. The characteristic of opportunistic network is that it does not need to establish a complete link between the source node and the destination node to transmit the message. The current opportunistic network mainly adopts the Epidemic algorithm (flooding algorithm), which uses the flooding method to transmit the message to the nodes that meet. This algorithm realizes the message exchange through the encounter between mobile nodes. node) forwards a copy of the message to the node it encounters that does not carry the message, and expects each node (destination node) to carry as many messages as possible. This method r...
