Embodiment Construction
[0041] A method for implementing video transmission applied to a vehicle ad hoc network in the present invention will be fully described below in conjunction with the accompanying drawings.
[0042] A method for implementing video transmission applied to a vehicle ad hoc network. The vehicular ad hoc network is composed of more than three nodes, and each node is not only a requester of video information (ie, source node), but also a provider of video information (ie, destination node), or a relayer of video information (ie, intermediate node ). Such as figure 1 As shown, the implementation method includes video request, response, maintenance and transmission processes.
[0043] Such as figure 2As shown, the implementation method uses the Linux kernel netfilter framework to set hook functions at the two hook points PRE_ROUTING and LOCAL_OUT to capture and process data packets flowing through the node network layer, and realize the establishment, maintenance and transmission...

The invention relates to a video transmission realization method applied to an on-vehicle self-organized network, wherein the video transmission realization method belongs to the field of on-vehicle self-organized network. The video transmission realization method comprises the steps of initiating a video request by a source node, initiating a video response by a destination node, initiating video transmission by the destination node and maintaining a video link. The video transmission realization method applied to the on-vehicle self-organized network has advantages of high speed, simple operation and high efficiency and settles the problems such as high topology structure change speed, limited network bandwidth and limited platform processing capability in the on-vehicle self-organized network. The video transmission realization method can be adapted with the characteristic of high topology structure change speed of the on-vehicle self-organized network and furthermore has advantages of reducing establishing cost and maintaining cost of video transmission link routing, realizing video transmission of the on-vehicle self-organized network, and realizing wide application prospect and high realistic meaning.
Description
technical field [0001] The invention belongs to the field of vehicle-mounted ad hoc network wireless communication, and in particular relates to a method for implementing video transmission applied to a vehicle-mounted ad hoc network. Background technique [0002] With the continuous development and progress of society, automobiles have become a necessary means of transportation for people to travel, and various traffic safety problems have also been brought about thereupon. Traffic accidents are known as the world's "number one killer" because of their extremely strong "lethality". The concept of vehicle network, one of the important foundations of intelligent transportation systems, was proposed under the background of this demand. The vehicle-mounted ad hoc network is an ad hoc network specially designed for inter-vehicle communication. It creatively applies ad hoc network technology to inter-vehicle communication, enabling drivers to obtain other vehicle status informati...
