1、（20_一届）本科毕业设计基于无线传感网络的数据采集系统设计无线传感器网络(WSN,WirelessSensorNetwork)是综合了传感器技术、嵌入式计算机技术、分布式信息处理技术、微电子技术和通信技术等各种先进现代技术为一体的，能够协作地进行实时监测、感知和采集网络分布区域内的各种环境或监测对象的信息，并对其进行处理，传输给用户终端的网络技术。本文将首先介绍无线传感器网络的概念和特点，并对无线传感器网络的发展历程现状和应用前景进行阐述。再探讨无线传感器网络技术发展屮面临的--些技术难点和挑战。然后重点的介绍了无线传感网络屮的路由协议。对已有主要的路由协议和

2、算法都做出了简要性的列举和介绍，并且对各种路由算法的性能优缺点进行了分析，通过对现有路由算法的归纳和比较，总结出了无线传感器路由协议和算法所需要具备的基本特征。最后针对传感节点的结构特点进行分析，提出传感器节点的低功耗设计策略。通过对无线传感器网络节点的各组成环节的功耗进行分析提出相应降低节点功耗的措施和方法。关键词：无线传感器网络，传感节点，协议栈，路由协议，低功耗DataAcquisitionSystemBasedonwirelesssensornetworksAbstractWirelesssensornetworkisacombinationofsens
