Problems solved by technology

The basic idea of ​​the direct data transmission method is that the source node carrying the data transmits the data to the destination node only when it encounters the destination node. Since each message is only transmitted once during the transmission process, the transmission efficiency is low and the delay is large. ; The basic idea of ​​flooding data transmission method is that the node carrying data in the network will transmit the data to any node and keep a copy of the data itself. Although this method has high transmission efficiency, it causes a huge network overhead

Abstract

The invention provides a data transmission method and system, terminal equipment and a computer readable storage medium, and the method comprises the steps: selecting a node which carries a data nodeand carries out the data transmission with the data node as an effective node, so as to form an effective node set; respectively calculating the quality evaluation degree of each effective node in theeffective node set; based on the quality evaluation degree calculation result, selecting the effective node with the minimum quality evaluation degree as the next hop node of data transmission to transmit the data. According to the embodiment of the invention, the data transmission efficiency can be ensured while the network connectivity is ensured at least.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a data transmission method, a data transmission system, a terminal device, and a computer-readable storage medium. Background technique [0002] With the development of wireless ad hoc networks, wireless ad hoc networks usually transmit data in the form of multi-hops. However, due to the limited energy of sensor nodes and other reasons, some nodes die prematurely due to excessive energy consumption, which eventually affects the entire network. Network connectivity. [0003] Currently commonly used data transmission methods mainly include: a direct data transmission method and a flooding data transmission method. The basic idea of ​​the direct data transmission method is that the source node carrying the data transmits the data to the destination node only when it encounters the destination node. Since each message is only transmitted once during the transmis...
