As IoT spread, various applications using them are proposed. On the other hands, new challenge that have not been considered on current Internet environment is encountered. In our research themes, we propose methods to increase Quality of Experience (QoE) by using IoT technology in office environment.
Moreover, we try to solve the problems for IoT technology.
