Design of Network Environment Advertisable Multipath Transmission Control System for Mobile Device Support

Uninterrupted wireless communication on the move is important for remote drone/robot operation, self-driving cars, and maritime autonomous surface ships. This paper describes a functional extension design of our previously developed fieldprogrammable gate array (FPGA)-based multipath transmission control system. The new network environment advertisable method uses the Wi-Fi round-trip time (RTT) and low-power wide-area (LPWA) networks to address the issue of not knowing whether handover is possible until the device is in motion, because Wi-Fi AP scanning is limited to the wireless communication range. We show how to apply the method to the hardware that we previously developed and its practical applicability through performance evaluation of Wi-Fi RTT and LPWA communication.
