Design and Implementation of a Home Automation System Based on ZigBee and 3G Terminal

With the recent technological advances in zigbee, 3G and embedded technology, development of home automation has been enabled and become dramatically feasible. Based on the advantage and feature of Zigbee and 3G, this paper introduces a home automation system. First of all, this paper discuss the network topology of system, which makes up of inner-net, home gateway and outer-net. The inner-net, consisting of subsystem, security alarm subsystem and smart appliance control subsystem, communicates with outer-net by home gateway. And then, this paper mainly analyzes hardware and software design of these subsystems and gateway and it gives an implement scheme. At last, the paper proposes a solution of low power strategy.
