【摘要】 无线传感器网络的测试工具对于传感器网络的深入研究和应用具有重要意义。提出了一种非打扰式的无线传感器网络测试方法,并介绍了基于该方法的无线传感器网络测试仪的设计思路和详细实现。该测试仪采用可编程逻辑阵列(FPGA)高速采集传感器节点的内部互连信息,并将采集的信息通过额外网络传输到测试服务器进行集中处理,还原节点状态信息和获取整个无线网络的通信情况,避免了对传感器网络节点运行和无线通信的影响。实验测试表明,该测试仪可以很好地获取节点状态,并在数据采集的过程中不干扰节点的正常工作。更多还原

【Abstract】 Wireless sensor network test tool is great significant for the wireless sensor network’s in-depth research and applications.A testing method of non-intrusive wireless sensor network was proposed,and the design and implementation of a wireless sensor network tester based on this method were introduced.This tester uses the FPGA to speedily collect the signal of the node inner communication without intrusive to work of the node,and then send the signal to the center servicer.With processing these signals,the center servicer can revert the communication of the node or all wireless sensor network.The experiment proved that this tester can be very good at collection of the nodes communication data without interference to the work of nodes.更多还原
