Evaluation of Wake-on-Demand Accurate Activation and In-Vehicle Wireless Connecation Control

Recently, many research studies have contributed to the connection of in-vehicle devices with a cloud network and to management of the status of these devices on a server outside the vehicle. For these cases, an in-vehicle router is important because in-vehicle devices communicate with the external server via the in-vehicle router. The in-vehicle router activates devices outside the vehicle as necessary and maintain a stable speed for the in-vehicle devices. We proposed two methods to reduce the inaccurate activation of wireless devices and improve the throughput for in-vehicle wireless communication. The proposed methods were evaluated through field tests. These results showed that the probability of false positives was reduced and the throughput for each passenger was improved for each vehicle. These two methods were integrated into one system, and the system was used to provide appropriate information only for users who visited a destination.
