Embodiment Construction

[0050] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0051] The technical scheme that the present invention solves the problems of the technologies described above is:

[0052] The present invention is based on the system model of the heterogeneous Internet of Vehicles, in which the vehicle terminal can be connected to the LTE base station through the LTE technology, and can also be connected to the WAVE roadside base station (RSU) through the WAVE technology. The data acquired on the sensor is used to predict the trajectory of the vehicle terminal. The central controller analyzes and calculates the data through cloud services, makes switching decisions and releases the decision information. The invention mainly solves the frequent switching problem caused...

Abstract

The invention requests to protect a heterogeneous Internet of Vehicles switching method based on vehicle trajectory prediction, which comprises the following steps of: step 1, establishing a vehicle-mounted heterogeneous network in an urban scene; step 2, establishing a vehicle trajectory prediction model based on LSTM and a convolutional social pool; step 3, predicting residence time of the vehicle terminal in each candidate network based on the vehicle trajectory predicted in the step 2; step 4, performing weight setting on a plurality of attributes comprising the residence time by utilizinga fuzzy analytic hierarchy process, and setting weights meeting corresponding requirements according to different services; and step 5, performing optimal network judgment based on a KL-TOPSIS algorithm. According to the heterogeneous Internet of Vehicles switching method, the switching frequency and the ping-pong switching frequency can be reduced.

Description

technical field [0001] The invention belongs to the technical field of heterogeneous Internet of Vehicles communication, and in particular relates to a switching method for heterogeneous Internet of Vehicles based on vehicle trajectory prediction. Background technique [0002] The Internet of Vehicles, also known as the Internet of Vehicles and the Internet of Vehicles, is the product of the interactive development and integration of the fields of intelligent transportation and the Internet of Things. The Internet of Vehicles has been regarded as an important part of the development of Intelligent Transportation System (Intelligence Transportation System, ITS) and smart city. It is expected to bring a series of new applications, from improving road safety to optimizing traffic efficiency, from autonomous driving to Internet access in vehicles anytime and anywhere. Connected vehicles will ultimately have a profound impact on society and the daily lives of millions of people ...
