Seamless Network Bridge for Supporting Interoperability UPnP-ZigBee

Universal Plug and Play (UPnP) can be applied many home appliances because of its straightforward implementation and zero configuration characteristics. However, it has limitation of the cost and spatial because it has to be used in IP based network. The proposed network bridge is capable of generating virtual Zigbee device without implementing each actual device which inserts an UPnP stack. This technique is promising for seamless inter-networking with Zigbee and UPnP network. Also, the architecture of the proposed network bridge can be applied implementation for a future smart home.
