Abstract
In recent years, the ZigBee network has been rapid develop in smart home. In order to solve the intercommunication barrier in heterogeneous wireless networks in the smart home, a wireless home gateway which is based on embedded is designed and implemented in this paper. The gateway is made up of the main controller S3C2440, the ZigBee module JN5148 and the Wi-Fi module VT6656. It is capable of converting Wi-Fi protocol data or ZigBee protocol data, transmitting them to each other and integration of heterogeneous wireless networks. This paper describes the design and implementation process of the gateway hardware and software, introduces the Wi-Fi protocol data and the ZigBee protocol data conversion approach, and resolve the bottleneck caused by the two protocol different transmission rates. Then the performance of the gateway is tested, and the results indicate the Wi-FiZigBee gateway is completely meeting the needs of the smart home.
