Abstract: Most home networks achieve wireless coverage based on WiFi and ZigBee,but these networks are sometimes unevenly covered due to wireless network devices with different configuration,and too many wireless network devices may lead to high-radiation energy.Aiming at these problems,this paper proposes a cooperative smart home network architecture based on Controller Area Network(CAN) and Bluetooth network,which is divided into backbone network and terminal network,and implements the prototype system.The backbone network is built by CAN,and the terminal network is set up by Bluetooth network.Experimental result shows that the system implemented by the proposed architecture has the advantages of wider coverage,higher communication quality and lower energy radiation,which can effectively support the application requirements of green home network.
