Abstract. In this paper, we combine the technique of ARM and ZigBee to design and implement the novel smart home system. Through analyzing the data transmission security enhancement model, we modify the traditional model with security concern. Each smart home system can be controlled by the server to facilitate access to residential property services, municipal services, such as weather forecast information. While using ZigBee as household interior various network can be easily will not have communication interface devices connected to the Internet gateway, does not need complex wiring or buy expensive appliances with communication interface. In the future research, we will numerically experiment our system and collect feedback for further optimization.
