Embodiment Construction

[0072] In urban environments, vehicle-to-vehicle data communication is increasingly required. How to enable the data requester to obtain the required data with less transmission delay is the core content of the solution of the present invention, that is, to select a low-delay path through the design method of the present invention among multiple candidate data transmission paths The data transmission path reduces the data transmission delay. In the following implementation description, the method and device of the present invention are applied to the following network model:

[0073] 1. All vehicles (nodes) are distributed in the urban traffic network (such as figure 1 shown), the trajectory of the node follows the urban traffic rules;

[0074] 2. Each node carries an electronic map display device, and the electronic map can obtain street traffic conditions, vehicle speed, traffic light scheduling status and recommended driving route functions;

[0075] 3. All nodes have a ...

Abstract

The invention discloses a data transmission path selection method based on vehicle density distribution. The method comprises the following steps of acquiring position information of a source node and a purpose node; selecting a transmission path and carrying out data packet forwarding in a street. By using the method of the invention, a packet loss and retransmission brought by a data transmission path failure generated because of a unnecessary routing void are avoided and a network load is reduced; a data transmission time delay state under the condition of sparse vehicles can be reflected and a data transmission time delay state under a vehicle jam (common) scene can be reflected too. The model is suitable for a more general scene.

Description

technical field [0001] The invention belongs to the application field of mobile wireless networks, and in particular relates to a data transmission path selection method based on vehicle density distribution. Background technique [0002] As an extension of the Internet of Things in the field of intelligent transportation, the Internet of Vehicles has attracted extensive attention from industry and academia in recent years. As more and more vehicles join the road traffic network and the cost of wireless communication decreases, more useful information can be fully exchanged between vehicles, and drivers can obtain higher safety and comfort in the process of driving vehicles. These are embodied in: emergency avoidance of traffic distress, effective dissemination of special vehicle warning information, driving route optimization, acquisition of road condition information, directional positioning broadcast of business advertisements on the road and remote acquisition of parking...
