Application Study Of Smart Home In Heterogeneous And Executable WSN

In recent years, smart home which based on the intelligent control, with its intelligentapplication brought big convenience in people’s lives, learning, works and so on, was veryfavorite. And its development is also growing rapidly. However, the current definition ofpeople’s misinterpretation and smart home industry is no uniform standard, leading todifferent products compatible integration between modules is very inconvenient,time-consuming re-assembly problems occur.The emergence of this issue will undoubtedly make greatdiscount in convenientservices of smart home. At the same time, it will also hinder the smart home rapiddevelopment. This topic starting from this issue, studied and designed a set of applicationsof heterogeneous and execution WSN in smart home.The network system is user-oriented,focusing on a core gateway, into three wireless communication networks perform aheterogeneous and execution WSN system. The detail tasks include the following threeaspects:1) Topics from the actual needs and the heterogeneous networks and WSN basic model,proposed a design ideas of heterogeneous and execution WSN which consist of internalsensor networks, external service networks and a core gateway. Meanwhile, the networksystem was separated into five parts. They are physical sensing device layer, networktransport layer, intelligent scheduling layer, external session layer, application layer.2) Stratified according to the network system, proposed project to achieve the requiredhardware and software operating platform. Aninternal complementarity sensor networkmodel was established, consists of Wmrnet network and RF network based on NRF24L01.Core gateway was based on AT91SAM9261embedded core board. Wi-Fi network was away supported to the visitors from the external part. Furthermore, PIC16LF1823microprocessor chip, a variety of sensors and actuators in the network system composed ofthe execution of the final nodes with one to one combination.3) In the hardware and software platforms selected, completed their correspondingsoftware program. Meanwhile, there is a strict and simple communication protocol used inthe network system. At last, Android phones were displayed on outcomes, acting as a client.
