The impact analysis of network quality for the smart space

We build up the global testbed for the mixed augmented based service of smart space on South Korea and Germany. In this paper, we analyze the influence factor on network to support a stable service of smart space. We measure for the fluctuation of network bandwidth, jitter and packet loss as a performance index in global testbed and select the packet loss to be the most important influence factor for the evaluation of testbed. Then, we propose the method to minimize the network bandwidth using an attitude tracking which can support transmission of 3D model for the mixed augmented based service for the realization of smart space. For the evaluation, we setup a function to control the real object installed in Germany and control it through virtual object in South Korea using palm based user interaction interface.
