Summary:
Due to the different coverage of different access technologies and network properties, it is one of the fundamental problems how to ensure that users can choose the most suitable network in the case of multi network selection, and can switch between different networks seamlessly, so as to get high-quality user service.This paper focuses on the heterogeneous Internet of Vehicles environment composed of LTE, WiFi, and DSRC, and combines single-user and group handover schemes according to the different states of the vehicle. When the vehicle is in an isolated state, the single-user vertical switching algorithm is adopted; when the vehicle is in the cluster head or cluster member state, the vertical switching algorithm of 'fleet' users is adopted. The simulation experiment is carried out by MATLAB, and the better performance of switching is obtained.
