Embedded Wireless Sensor Network Gateway Design and Remote Maintenance
In order to solve the maintenance inconvenient problem of software system of wireless sensor network gateway,a wireless sensor network gateway based on ARM CortexA-8 embedded platform is developed.The hardware design of the gateway and the software implementation method on Linux operating system platform are expounded,and the interaction between the wireless sensor network and the Internet is realized.Besides,in the C/S mode,the remote maintenance software of the gateway is developed,which adopts TCP/IP protocol to ensure the reliability of data transmission.Online upgrade or update of the software system are implemented by u sing MTD.The experimental results show that the gateway operats stable and reliable,and system maintenance is convenient and efficient.
