基于WMSNs的图像数据传输系统设计与实现

摘要

无线多媒体传感器网络（ WMSNs）节点存在功耗大、体积大和抗损毁性差等问题，且不适合大规模使用。该研究围绕WMSNs节点的关键技术展开研究，设计并实现了一个图像数据无线传输的低功耗、高效率的系统，该系统采用三层网络结构进行图像数据无线传输，构造了性能优化、结构优良的WMSNs，以此解决了WMSNs的图像传输关键问题。在搭建的开发与测试环境中，完成了节点通信距离的测试和节点功耗测试。测试结果表明：该测试平台性能良好，能够实现图像数据的可靠传输。该研究为WMSNs图像数据传输系统设计提供研究基础和思路。%Nodes of wireless multimedia sensor networks ( WMSNs ) has problems including large power consumption,large size and poor resistance to damage,which is not suitable for large-scale usage,an image data wireless transmission system of low power consumption and high efficiency is designed and realized based on research of key technology of WMSNs node,three-layer network structure is used for image data wireless transmission to form WMSNs with optimized performance and excellent structure,which solve key problems of image transmission of WMSNs. Communication distance test and power consumption test of nodes are completed in development and test system and environment. Test results show that performance of the test platform of is excellent,and image datas can be reliably transmitted. The research provides reaserch basis and ideas for design of WMSNs image data transmission system.
