Applying device discovery methods for home network management

Currently there are still many devices that do not support the standards like UPnP, WSD etc. in home networks, thus, we should incorporate some standard methods with the other methods in order to get the information about the devices. In other words, a detector should complete the information by gathering the peripheral information, e.g. host name, OS version, the valid ports etc. Even if it can get the precise information from UPnP devices, the information is not always sufficient for the remote support service. The detection methods of device discovery are classified into two groups by their characteristics: the active detection and the passive detection. We present a practical method of device discovery, which combines the active detection and the passive detection, and described their characteristics by showing some experimental results.
