AbstractA new era of mobile Internet has been created with the progressive wireless Internet technology;

hence, the demand of telematics is getting higher. However, the characteristics of high mobility vehicle

highlight the power and hardware limitations of communication device itself. Through the OpenFlow

technology, the quality of wireless performance which is lower by switching from the device to the

base station on the ground could be improved. Mobile communication regards moving together groups

as an overall concept which particularly suit for improving the quality of vehicle communication.

When the vehicle is moving, the mobile nodes were detected from the platform that the vehicle is

moving from large 3G coverage into the short range of WiFi service range; then, leave this WiFi

service range to another range of 3G services. Meanwhile, this phenomenon will result in frequent

vertical switching within short times, and it decreases the efficiency of system and decline service

quality. The experiment showed that the procedure of overall efficiency is insignificant while mobile

nodes are switching from 3G basestation to WiFi coverage.
