Transparent upnp interactions over global network

摘要

Universal Plug and Play (UPnP) has been proposed by Microsoft for realization of interactions among home appliances (e.g., TVs, air conditioners, and lighting devices) and information devices (e.g., PCs and PDAs) on a home local network. UPnP assumes to be used on a local network. Difficulties exist when establishing a communication link between two local networks across the Internet. In this paper, we propose a new device interaction method across the Internet with web service technology. We implement prototype system and make evaluation about latency.
