Research on smart living technology based on WSN

As the development of sensor technology and communication technology, the realization of smart home is not longer out of reach. This paper provides a design of smart home system based on wireless sensor network (WSN) within the ZigBee criterion. For the different network condition of different houses, we employ different networks (Internet or UMTS) to achieve remote control of the house´s electric equipments. As the most important part of smart home system, a gateway is not only the bridge of two heterogeneous networks but also the controller. We provide two gateway structures--the WSN integrate Internet (WII) gateway and the WSN integrate UMTS (WIU) gateway--to achieve information exchange between heterogeneous networks. We also give appropriate hardware and software schemes to fulfill these gateway structures.
