Application Of UPnP And ZigBee Hybrid Network In Intelligent Home Network

With the coming of Internet of things, the popularity of micro-computer and the rapid and steady development of communication technology. The whole society has entered the era of intelligent interconnection. People have not satisfied with the simple control of physical devices too active. Let physical equipment intelligent, equipment interconnection and intelligent interaction, resource sharing and remote interaction are the requirements of the Internet of things. Digital home network is a part of the Internet of things, and closely linked with our lives. The realization of intelligent, networked home control is the most direct way that we enjoy the wisdom network of things. Based on the technology of the Internet of things, The modernization of home control will not be an isolated information island, she take the network as the core, and the target is to make all information devices capable of intelligent interconnection, interaction, sharing of information resources, provide a convenient and ubiquitous control terminal for the user.In order to resolve the incompatibility of interconnection for many kinds of heterogeneous home product in the modern home network.This paper let UPnP technology as the core, proposed a multifunctional common UPnP bridge, to respond to the complex heterogeneous home network device. The bridge can connect a variety of network device at the same time and is backwards compatible with the new protocol equipment. The bridge using the method of hierarchical processing,it provide a independent, protocol-related plug-in module for each heterogeneous network protocol at the bottom,and load to the bridge dynamically.this method result in a semi-open adapter engine. UPnP network shield the differences of various hardware and heterogeneous networks, and form a unified perception layer. At the same time,UPnP will provides a unified connection, interaction and communication mechanism for the upper application.At the end, the experimental results show that under the condition of without changing the bridge’s original structure, the bridge can dynamically provide or cancel the bridging support to ZigBee network,and provides a completely open and independent support for the new protocol.Use UPnP as the core network,the UPnP bridge can perfectly resolves the connectivity among many kinds of heterogeneous family production,and achieve a resource sharing and fusion of heterogeneous networks.
