The UPnP is middleware architecture that supports dynamic distributed computing environment. It has many good features for possible use as middleware in robot system integration. There is a need for bulky binary data transmission between distributed robot S/W components. Since the UPnP utilizes SOAP protocol for message transmission, however, it is not efficient to send bulky binary data. In order to overcome this weak point, this paper proposes UPnP-MTOM, MTOM (Message Transmission Optimization Mechanism) implementation over UPnP, as an efficient way for bulky binary data transmission with UPnP messages. This paper presents our implementation method and experimental results of the UPnP-MTOM implementation.
