摘要： 针对无线传感器网络与Internet网络的通信协议不兼容问题,利用低功耗蓝牙4.0与第三代移动通信技术,设计一种无线传感器网关。硬件设计方面,使用基于ARM Cortex-A8的S5PV210作为主处理器,使CC2540蓝牙模块与无线传感器节点相连接,控制3G模块进行远程通信。软件设计方面,基于Android操作系统实现无线传感器网络与Internet网络的数据接收、网络协议转换、交互控制等功能。测试结果表明,该网关具有较低的接收与转发数据丢包率、处理时延及功耗,可保证无线传感器网络与Internet网络的高效实时通信。

Abstract: Aiming at the problem that the communication protocol of Wireless Sensor Network(WSN)is not incompatibility with the Internet network,a wireless sensor gateway based on low-power bluetooth 4.0 communication technology and 3G is designed.The primary processor of the gateway is designed by microprocessor S5PV210,which is used to control the communication between CC2540 bluetooth module and wireless sensor node and operate the 3G module to communicate with Internet.The software platform of the gateway is based on Android operating system,which realizes data collection,network protocol conversion,interactive control between WSN and Internet network.Test result shows that the gateway has low packet loss rate of receive and forward data,latency and power consumption,and it can ensure efficient communication between WSN and Internet network.

Key words: Wireless Sensor Network(WSN), bluetooth 4.0, Android system, wireless sensor gateway, TCP/IP protocol
