Problems solved by technology

[0003] The current vehicle-mounted terminal networking usually adopts the 802.11p ad hoc network method of the vehicle ad-hoc network (VANET, Vehicular ad-hocnetwork), which uses the sequence destination node distance vector routing protocol (DSDV, Destination-Sequenced Distance-Vector Routing) table Drive routing, but the existing ad hoc network mode using DSDV protocol table-driven routing has a large overhead and a large data delay
On-demand networking methods such as Dynamic Source Routing (DSR, Dynamic Source Routing), Ad hoc On-demand Distance Vector Routing (AODV, Ad hoc On-demand Distance Vector Routing), Temporary Scheduled Routing Algorithm (TORA, Temporally Ordered Routing Algorithm) and other methods can temporarily form a network according to needs, but its network structure is often a more complex tree structure or topology structure, which includes subnets and subnet gateways, so that The transmission of data packets needs to pass through subnets and subnet gateways. Therefore, the transmission process is more complicated, more routing judgments are required, and the network overhead is larger; moreover, due to the complex topology structure, the networking will be inflexible and inefficient, which will lead to network failures. The delay is long, and the network structure cannot be updated in time according to the structural changes of the actual nodes

Embodiment 1

[0070] figure 1 It is a schematic diagram of the implementation process of the ad hoc network method based on the vehicle terminal in the embodiment of the present invention Figure 1 ; The method is applied to a vehicle terminal, such as a vehicle navigation etc.; as figure 1 As shown, the method includes:

[0071] Step S101: the target vehicle-mounted terminal obtains the first physical state information of the target vehicle corresponding to itself;

[0072] In this embodiment, the first physical state information represents at least the moving state of the target vehicle and the location information of the target vehicle; specifically, the first physical state information may represent the moving direction, speed, acceleration, And the geographic location of the vehicle, such as latitude and longitude.

[0073] Step S102: The target vehicle-mounted terminal, based at least on the first physical state information of the target vehicle, uses itself as a target node to for...

Embodiment 2

[0129] Embodiments of the present invention provide a method for ad hoc networking based on vehicle-mounted terminals. Specifically, embodiments of the present invention provide a method for cascading ad hoc networks based on geographical information that is applied to vehicle-mounted terminals. In this way, it is different from the existing complex Compared with the structure of the Internet of Vehicles, the method described in the embodiment of the present invention can reduce network overhead and improve the networking efficiency of the Internet of Vehicles. Such as Figure 5 shown, including:

[0130] Step 501: The target vehicle-mounted terminal acquires first physical state information such as the moving direction, speed, acceleration, and latitude and longitude of the target vehicle corresponding to itself;

[0131] Step 502: The target vehicle-mounted terminal judges whether the acquired acceleration and speed are correspondingly higher than the speed threshold and th...

Embodiment 3

[0142] Based on the method described in Embodiment 1 or Embodiment 2, in order to facilitate real-time adjustment of the Internet of Vehicles according to the moving state of the vehicle, in this embodiment, the target vehicle-mounted terminal will obtain the current fourth physical state information of the target vehicle corresponding to itself; Then detect whether the moving state of the target vehicle represented by the fourth physical state information satisfies the second preset rule; when the second preset rule is satisfied, transfer the target node corresponding to the target vehicle terminal from the vehicle removed from the Internet; specifically, Image 6 It is a schematic diagram of the implementation process of exiting the Internet of Vehicles according to the embodiment of the present invention, such as Image 6 shown, including:

[0143] Step 601: The target vehicle-mounted terminal continuously acquires the current fourth physical state information of the targe...

Abstract

The embodiment of the invention discloses a self networking method based on a vehicle-mounted terminal. The method comprises the following steps: a target vehicle-mounted terminal obtains first physical state information of a corresponding target vehicle, wherein the first physical state information at least characterizes the moving state of the target vehicle and the location information of the target vehicle; and the target vehicle-mounted terminal performs networking at least based on the first physical state information of the target vehicle by using itself as a target node in a link type structure manner, so that the target node is connected with two adjacent nodes at most. The embodiment of the invention further discloses a vehicle-mounted terminal.

Description

technical field [0001] The invention relates to mobile ad hoc (Ad Hoc) network technology, in particular to an ad hoc network method based on a vehicle-mounted terminal and the vehicle-mounted terminal. Background technique [0002] Vehicles drive to road sections with poor mobile Internet, such as mountains, caves, and sea-crossing bridges. Once a vehicle accident occurs, or congestion caused by any other reason, the vehicle usually cannot receive effective guidance and rescue, and cannot effectively carry out rescue or rescue. save yourself. At this time, if the communication function of fast networking is provided between the vehicles, the above situation can be better solved. [0003] The current vehicle-mounted terminal networking usually adopts the 802.11p ad hoc network method of the vehicle ad-hoc network (VANET, Vehicular ad-hocnetwork), which uses the sequence destination node distance vector routing protocol (DSDV, Destination-Sequenced Distance-Vector Routing) t...
