本文基于ARM9平台,设计并实现了一种能与多种通信网络进行数据交换的无线传感网网关。该网关通过多种通信模块的接入,应用多线程技术控制各种通信方式并行执行,实现了无线传感器网络与以太网、GPRS移动通信网、无线局域网等多种网络的互联互通。系统性能测试表明,该网关在吞吐量、时延、丢包率等性能指标上都有较为优越的表现,完全可以在实际网络环境下高性能的运行。
We design a wireless sensor network gateway based on ARM9 platform that meets the aata exchange demand of multi-communication mode. In order to realize the communication between wireless sensor networks and other networks such as Ethernet, GPRS and WLAN, the gateway makes use of multi-thread technology to control all means of communication executing in parallel through a variety of communication modules access, The result of simulation show that the gateway has a satisfactory performance in throughput, latency, packet loss rate, etc and runs with a high efficiency in real network environment.
