Universal UPnP bridge for embedded non-IP device with heterogeneous network interfaces

This paper proposes an architecture of Universal UPnP Bridge that interconnects embedded non-IP devices1 with UPnP network in a fairly easy manner. We define non-IP device description, extended UPnP service description and message field description in order to reduce the amount of effort required to support various non-IP devices. By the descriptions and a message conversion module above, embedded non-IP devices can be connected to UPnP network without additional programming to convert different message formats. The proposed bridge guarantees seamless interaction by abstracting non-IP devices as virtual UPnP devices that performs generic UPnP device´s functionalities. And we demonstrate our proposed architecture through implementation and evaluation.
