specific Embodiment approach 1

[0078] This embodiment is a data-aware routing method for self-organized Internet of Vehicles, including the following steps:

[0079] S1. Collect large-scale real vehicle operating data and build network and perception models:

[0080] The data used in this example is the real operating data of more than 10,000 taxis and more than 3,000 buses in Shenzhen, that is, vehicle fine-grained location tracking data and vehicle real-time orientation and speed perception data, from January 2015 to December 2016 .

[0081] Vehicle nodes are equipped with GPS position and speed sensing devices to obtain real-time node location information, running direction and instantaneous speed. Taxi vehicle nodes can also obtain the passenger status of vehicle nodes (ie, empty or heavy load). The data structure of the perception data of the vehicle node is described as follows:

[0082] Vehicle ID Longitude Latitude Speed angle Timestamp Status

[0083] Among them, Vehicl...

Abstract

The invention discloses a data awareness routing method of a self-organizing Internet of Vehicles and a system thereof, a storage medium and equipment, and belongs to the technical field of Internet of Vehicles communication. The problem that an existing routing method is not suitable for a vehicle network is solved. The method comprises the following steps: performing data routing in the Internet of Vehicles based on an Internet of Vehicles routing algorithm of joint scheduling; enabling the routing algorithm of the Internet of Vehicles of joint scheduling to determine the overall transmission performance of the the Internet of Vehicles network, as well as the transmission delay and transmission cost of the data packet according to the source node and destination node of each data packet p in the set of data packets that the Internet of Vehicles network needs to transmit, and determining an optimal transmission strategy, modeling a position change process of a vehicle node by adopting a multi-order Markov chain, and predicting and estimating a next moment and a plurality of moments in the future under the condition that the positions of previous moments are given; and realizing data routing in the Internet of Vehicles in combination with an optimal transmission strategy based on the actual position values and the predicted estimated values of the vehicle nodes. The method is mainly used for data communication of the vehicle self-organizing network.

Description

technical field [0001] The invention relates to a routing method for a vehicle self-organizing network, and belongs to the technical field of vehicle networking communication. Background technique [0002] With the continuous development of wireless mobile communication technology and short-distance wireless communication technology, and the popularization of wireless communication equipment and terminals, the Wireless Vehicular Networks (Wireless Vehicular Networks) has emerged as the times require. Through the medium and short-range wireless communication equipment installed on the vehicle, such as dedicated short-range wireless communication (DSRC), wireless local area network IEEE 802.11 (WiFi), etc., wireless communication can be formed between vehicles within a certain distance; after installing a wireless base station on the roadside , Wireless information interaction can also be realized between vehicles and roadside facilities. Vehicle nodes and roadside facility sy...
