摘要
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,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 issue.In that case,it shows and describes 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 sys-tem can effectively test the loss rate of the WSN packet,and provides an effective technical solution for the WSN network performance a-nalysis.
