Abstract
To release the connection problem between different kinds of wireless communication technologies in conventional smart home system, a new direct-connected intelligent home gateway between two different wireless communication technologies was designed. This gateway was based on ARM920T embedded processor S3C2440A, ARM Linux operation system and new communication technology combining Zigbee and Wireless-Fidelity ( Wi-Fi) , was considered to achieve the personalized objective of remote monitoring, home security, home appliances control and so on. An embedded Web server was built in ARM9 processor, the Wi-Fi module and Zigbee module were expanded to achieve the construction of wireless network and the connection to Internet, and the hardware structure and software process were shown too. The experimental results show that, the packet loss rate and response time of this new gateway are less than the other gateways like wire line network and Wi-Fi bluetooth wireless network, and it can be applied to the smart home system.
