Implementation of dual transmission function for remote vehicle controls

Network-supported remote vehicle control is expected to improve efficiency in the future society. Our research target is to develop a cost-effective real-time control technique using the broadband wireless network infrastructure. To improve the transmission performance using broadband wireless access networks, we have already proposed dual transmission protocol (DTP) that uses independent two transmission channels simultaneously. In this paper, we show experimental evaluations of DTP implementation. Those evaluations show improved frame loss ratio of video signals and enhanced controllability of remotely controlled vehicle (Internet-connected model car). Those results indicate DTP's effectiveness and feasibility.
