Recently, the Univeral Plug and Play (UPnP) Form has relased UPnP Cloud, which is an extension to the basic UPnP architecture that enables device to device connectivity across the Internet. UPnP Cloud uses the Extensible Messaging and Presence Protocol (XMPP) to connect devices located in different domains. In this paper, the details of the UPnP Cloud are presented. We demonstrate how UPnP Cloud enables contents to be shared remotely, and how it can be used in connection with DLNA.

This paper presents an architecture of UPnP Bridge that allows controlling Non-iP devices from UPnP control point, without modification to Non-IP device or UPnP control point implementations. UPnP devices must provide SSDP discovery, SOAP control and GENA event processes. To represent Non-IP devices to UPnP devices, UPnP Bridge provides these functionalities on behalf of Non-IP devices. We provides two method to interoperability between UPnP and Non-IP devices, Message Field Description, Non-UPnP Proxy devices. And solution to integrate heterogeneous networking standards(RS232C, CAN, IEEE1394, USB) is provided.

UPnP(Universal Plug and Play) is commercial product for the first time in home network middlewares, but it has problem that it has no security standards in UPnP specification. In this paper, we present UPnP security model. It is based on XML Signature of XML Security. It provides UPnP with secure services which are device control message authentication and user access level control. It is independent of UPnP modules and has mobility of secure service modules for non secure ability user part. We conclude this paper with an example of applying UPnP Security model to the UPnP audio device control and an test example.

This paper presents an architecture of UPnP Bridge for interconnecting Non-lP devices with heterogeneous network interfaces to UPnP devices on UPnP networks. The proposed UPnP Bridge provides a Virtual UPnP device that performs generic UPnP Device's functionalities on behalf of Non-lP device. This paper defines 3 types of descriptions, Device Description, Message Field Description, and Extended UPnP Service Description in order to reduce the amount of effort required to connect a non-lP device with a new interface or message format to UPnP network. By these three types of descriptions and Message conversion module, developers for Non-lP devices can easily connect the devices to UPnP network without additional programming. So UPnP control point controls Non-lP devices as generic UPnP device. Some experiments validate the proposed architecture, which are performed on a test bed consisting of UPnP network the proposed bridge, and non-lP devices with CAN and RS232 interfaces.

The Universal Plug and Play (UPnP) specification permits networked devices to discover each other and to provide diverse services in the home network environment. Recently, new paradigms such as mobile connected computing, cloud-based service delivery, smart device content sharing, and Internet of Things (IoT) have emerged, but the home network based UPnP shows functional limitations in supporting such paradigms. To support them, the UPnP Forum has recently extended the capabilities of the existing UPnP, calling it UPnP+. In this paper, the UPnP Device Architecture V2.0 (UDA 2.0), which forms the basis of UPnP+, is presented. We present how UDA 2.0 enables the expansion of the home network to wide-area networks and non-IP device domains.

According to the development of home-network, home-network middleware supporting interoperability between devices connecting to home-network has been variously Proposed. As a typical middleware, UPnP and Jini are developed individually. So, to extend the usage of home-network, it is necessary to have connections among various home-network middleware. In this paper, we study about home-network middleware UPnP and Jini, and design and implement UPnP-to-Jini service which allows Jini client to use UPnP device using the speciality of UPnP performance process. Using application of light on-off we implemented the connection of them.

In this paper, we have implemented UPnP Devices which emulate a Control Point, a Light Controller, and a Digital TV. The Control Point has been developed on Linux host system by using C language. The UPnP Devices emulating the Digital TV and Light Controller are running on embedded linux developer board. For the development of UPnP Devices, UPnP SDK API Vl.04 made by Intel Co. Ltd. has been ported on Assabet Linux Reference board to implement the UPnP protocol. After we analyze and design some services of Digital TV device, we have applied UPnP Device program to those devices. UPnP SDK vl .04 consists of APIs which support HTTP, SSDP, SOAP, GENA and XML DOM Level-1 that are cores of UPnP protocol. The C program written for the UPnP Control Point has been compiled and executed on Linux-based PC. The embedded system running on Embedded Linux OS has been connected all together through Ethernet which allows IP-based communications. Under this environment, the UPnP programs are being executed on each device. Control Point, when in operational mode, discovers UPnP Devices on the network and displays the device list on the consol. By selecting one of the functionalities of the device services that are displayed on the Control Point, the controllability has been accomplished. The experiment that we performed in this thesis have revealed that the Control Point and UPnP Devices have supported the protocols including SSDP, SOAP, GENA, and DHCP.

Devices compliant to the Universal Plug and Play (UPnP) Audio Video (A/V) specifications can easily establish multimedia home networks through zero or auto configuration. Despite the existing UPnP certification process many issues concerning interoperability still arise. Capabilities may not be fully implemented or there may be codec issues. Therefore, a means to check and verity interoperability prior to product purchasing or usage is necessary. In this paper, an implementation of a portable control point is proposed to store and manage UPnP device capability information. The portable control point can be used to find UPnP A/V compliant devices that are most compatible.

The control of electrical appliances residing in the home network can be accomplished via Internet with the UPnP expansion without modifying an existing UPnP. In this paper, we propose the Internet Gateway that consists of an UPnP IGD(Internet Gateway Device) DCP(Device Control Protocol) and an UPnP Bridge as a system to control electrical appliances of home network. UPnP IGD DCP is to enable the configurable initiation and sharing of Internet connections as well as assuring advanced connection-management features and management of host configuration service. It also supports transparent Internet access by non-UPnP-certified devices. UPnP Bridge searches for local home network devices by sending control messages, while control point of UPnP Bridge looks up devices of interest on the Internet, subsequently furnishing the inter-networking controlling among devices which belong to different home network systems. With our approach, devices on one home network can control home electrical appliances on the other hone network via Internet through IGD DCP with control commands of UPnP.
