Problems solved by technology

The related technology adopts a single backbone node mode, and the failure of this node will cause the network to be disconnected, seriously affecting the transmission quality
In addition, the related technology only considers a single influencing factor when selecting backbone vehicles, which may lead to frequent changes in the speed of the selected backbone vehicles, and it is easy to leave the area where it is located, making the backbone network unstable, so that information cannot be transmitted quickly and stably, resulting in waste of time and energy

Abstract

The invention discloses a data transmission method based on fuzzy logic and network coding. The data transmission method includes the following steps of dividing a specified road segment into a plurality of sub-segments; selecting a backbone vehicle on each sub-segment, wherein the backbone vehicle broadcasting the information to notify other vehicles; forming a vehicle network of the specified road segment based on the backbone vehicle of each sub-segment; and carrying out the data transmission based on network coding according to the vehicle network of the specified road segment. The data transmission method is advantageous in that the vehicle data transmission is stable and the time and energy cost for changing backbone vehicles are reduced.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a data transmission method based on fuzzy logic and network coding. Background technique [0002] The vehicle-mounted network is a mobile ad hoc network composed of a large number of sensor nodes equipped with perception, storage, data processing and wireless communication capabilities loaded on fast-moving vehicles. On the other hand, building a backbone network transmission mechanism can effectively improve data transmission efficiency. [0003] At present, some researchers have studied the auxiliary information transmission of the backbone network in the vehicle network. The relevant technology adopts a single backbone node mode, and the failure of this node will cause the network to be disconnected, seriously affecting the transmission quality. In addition, the related technology only considers a single influencing factor when selecting backbone vehicles, which may lead to ...
