Which Devices are Connected around us?

There are various IoT devices connected each other; the number of those devices is expected to increase. If IoT end devices are connected to abnormal network or malicious devices, they will be attacked or eavesdropped on. In this paper, we suggest an Active Connection Visualization which visualizes the connections of IoT end devices on wireless networks nearby. To visualize the active connections, we collected the RSSI value which describes the strength of signal received, and the relative direction information of the IoT end devices from the device to visualize their connections.
