Internet Home Network Electrical Appliance Control on the Internet with the UPnP Expansion

Electrical appliances of home network via the Internet can be controlled with the UPnP expansion like ones in the same home network without modification of existing UPnP. In this paper, we propose Internet Gateway that consists of UPnP IGD(Internet Gateway Device) DCP(Device Control Protocol) and the UPnP Bridge for control electrical appliance of Internet home network. UPnP IGD DCP is configurable initiation and sharing of Internet connections, advanced connection-management, management of host configuration, and supports transparent Internet access by non-UPnP-certified devices. UPnP Bridge searches for local home network devices by sending control messages. Control Point of UPnP Bridge searches for devices of interest on the Internet and can deliver the control devices on other home networks to device within its home network.With our approach, devices can control home electrical appliances via internet through IGD DCP on other home network with control commands of UPnP.
