摘要
WSN无线通信节点传输可靠性测试是物联网开发研究中重要理论与实践问题;因此提出了一种基于新型串口级联HUB总线通信与星型WSN网络对比的实践方案;文章阐述该WSN组网可靠性测试系统的基本思路、有线通信硬件SCI-HUB集线器的硬件设计、无线通信WSN节点的软硬件设计及PC机方通信测试软件设计;理论分析及实践表明,该方案可有效测试WSN无线通信节点的丢包率,测试样本的丢包率一般在98%以上,为分析WSN网络性能提供了一种切实有效的技术方案。
The reliability evaluating of WSN network is an important theoretical and practical issues. In that case, it shows and describes a practices based on a new SCI--HUB. This paper describes the idea of reliability evaluating of WSN network, the hardware design of the SCI-- HUB, the hardware and software design of WSN node and the software of PC. Theoretical analysis and practice shows that the system can effectively test the loss rate of the WSN packet, and the loss rate of the sample in the paper is generally more than 98 %, and provides an effective technical solution for the WSN network performance analysis.
