The Universal Plug and Play (UPnP) specification enables sharing of diverse multimedia contents among different devices. Contents discovered via UPnP are organized using directory hierarchy. If there are multiple sources of content providers and if the directory becomes large, managing and searching of the shared contents can be difficult. In this paper, an enhanced contents searching method is proposed by using semantic annotations. UPnP metadata is expanded to include semantic annotations to enable natural contents searching.

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.

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.

Middleware enables different networking devices and protocols to inter-operate in ubiquitous home network environments. The UPnP(Universal Plug and Play) middleware, which runs on a PC and is based on the IPv4 protocol, has attracted much interest in the field of home network research since it has versatility The UPnP, however, cannot be easily accessed via the public Internet since the UPnP devices that provide services and the Control Points that control the devices are configured with non-routable local private or Auto IP networks. The critical question is how to access UPnP network via the public Internet. The purpose of this paper is to deal with the non-routability problem in local private and Auto IP networks by improving the conventional Control Point used in UPnP middleware-based home networks. For this purpose, this paper proposes an improved Control Point for accessing and controlling the home network from remote sites via the public Internet, by adding a web server to the conventional Control Point. The improved Control Point is implemented in an embedded GNU/Linux system running on an ARM9 platform. Also this paper implements the security of the home network system based on the UPnP (Universal Plug and Play), adding VPN (Virtual Private Network) router that uses the IPsec to the home network system which is consisted of the ARM9 and the Embedded Linux.

With the increased demand of ubiquitous home services, intelligent robots have wide attentions. This kind of robots offer various services through middleware components which can connect with remote servers. In this paper we present an UPnP(Universal Plug and Play) based open-source software framework which makes control the robots remotely. This UPnP architecture for home networking can provide various communication methodologies like command control, eventing, presentation with web services and so on. This paper shows successful implementation results on two real platforms.

In this article, it has been shown that penises devices such as illumination facilities, heating/cooling systems and security equipment can be controlled even outside premises using UPnP (Universal Plug and Play) applicable to the Internet or cellular phone services. To load UPnP protocol into each device, current manufacturers will be required to port flexible OS (Operating System), that is, Windows or Linux to these premises devices. Furthermore, prospective users want to experience a variety of specific functions based on more standardized and stable network. This study aims to provide application by implementing these functions on the Linux system.

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.
