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 present invention claims a method for switching heterogeneous Internet of Vehicles based on vehicle trajectory prediction, which includes the following steps: Step 1, building a vehicle-mounted heterogeneous network in an urban scene, and Step 2, building a vehicle trajectory based on LSTM and convolutional social pool Prediction model; step 3, based on the vehicle trajectory predicted in step 2, predict the residence time of the vehicle terminal in each candidate network; step 4, use the fuzzy analytic hierarchy process to set the weight of multiple attributes including the residence time , set weights that meet the corresponding requirements according to different services; step 5, make an optimal network decision based on the KL-TOPSIS algorithm. The invention can reduce the switching times and the ping-pong switching times.

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 ...
