Design of Mobile Device Cooperative Transmission System under Wireless Network Fluctuation

With the development of transportation network, the scale of intelligent vehicle network is getting bigger and bigger. Mobile vehicles retain a large amount of data information in the Intelligent vehicle Network, which can be used to analyze network performance and provide various services. If various information in the region can be collected through the network platform, it will be conducive to the optimization and upgrading of the whole network and the technology. The instability of wireless link limits the information interaction of mobile devices in the Internet of vehicles. In order to realize automatic transmission of vehicle files and other data under wireless network fluctuation, we propose a vehicle wireless transmission system. The proposed system can realize on-line detection of monitored vehicles and automatic transmission of files and data to be transferred. At the same time, considering that some systems in the Internet of vehicles are not transmitted as the main business, in order to improve the transmission efficiency, a strategy is proposed to adjust the transmission data by taking mobile vehicles as the analysis end. According to the task to be transmitted and the real-time state of the network, the transport policy can reasonably schedule the task. A lot of measurement results show that the system can make full use of bandwidth resources and realize automatic transmission of information.
