| With the rapid improvement of our lives, there is a growing need for family lifestyle in safety, comfort and energy saving. The development of Internet technology makes it reliable for home network. Many manufacturers such as Haier and Lenovo have made some researches. It would be a wonderful feeling if mobile terminal could control devices in the house conveniently.Firstly this article researches on the mobile control technology in home network. It is based on the needs for mobility, security, scalability and the failure rate decrease. Then it chooses DLNA as a typical mobile control technology. DLNA focuses on the mobile terminal operation control with home media equipment and computers, which allows users to realize the sharing of media files. The article divides the control system into local and remote control model based on DLNA, using the ideas of MVC and realizing six functional points:application initialization, device searching, equipment movement, content browsing, play control and state changing.Secondly the article introduces a new smart home networking technology-OpenFlow in the smart home control system based on DLNA. It has advantages over the existing home networking technologies considering the control and observation. In the OpenFlow network, the routing function is separated from the switch by a unified controller to manage network packet transmission path. Based on this mechanism, we make an OpenFlow home network design and then test the network performance, including throughput and latency time.Finally it makes a validation on the self-developed system with OpenFlow-based home network to verify the application of the DLNA mobile technology on OpenFlow networking. |
