Ipv6-based Smart Home Networks Research

The concept of family information network and smart home is appeared with the improvement of appliances and the universal information technology. More and more families are urgent to get information of outside world at home anytime or to control appliances from outside, even implement the smart home. The invention of IPv6 inspires the implement of these ideas. IPv6 provides sufficient IP address. Not only each appliance can be assigned to a global IPv6 address, with which an appliance can connect to the internet, so as to solve the technical problem of the construction of family network system, caused by IPv4 address shortage, but the advantage of powerful auto-configuration capability of IPv6 and its service saves nearly all the work of configuration when a new appliance is added. With the advantages of IPv6, which have talked about, high security and support mobile ability and Qos, IPv6 opens the era of smart home.Firstly, the essay introduces the source and significance of the theme, and analyzes the research status at home and abroad of smart home. Lack of a clear international standard is the major factor of limiting the development of the smart home systems .According to this problem and the advantage of IPv6 on the construction of home information network, the development direction of future smart home based on IPv6 is proposed in the papers.Secondly, IPv6 is meticulously analyzed, including protocol feature, address and transitional technique, as well as support technique for appliance. According to the classification of network and appliance, home network is classified into three types, that is, A/V network, data transmission network and low-rate appliance control network. The three networks interconnect through home gateway, and each of them adopts different physical and communication protocol, which Home gateway has. According to the feature of home environment, each sub-network is separately designed. We adopt combined network plan with Bluetooth, IEEE1394 and code technique to construct home network and integrate the home network with Jini technique.At last, we analyze architecture and function of home gateway, and design the appliance control network, which is composed of appliance information register, appliance status inquiry and appliance control. And the appliance local-remote control based on C/S is implemented by WinSockets.
