1、本科毕业设计(20届)无线传感器网络路由协议研究39摘要【摘要】随着微型传感器技术、无线通信技术、微机电系统和嵌入式技术的飞速发展,集数据采集、处理及通信功能于一体的无线传感器网络开始得到广泛的研究。而路由协议是网络传感器节点互相通信的基础,同时也是网络层的主要功能。所以对路由协议的研究是非常必要的。本文主要对无线传感器网络路由协议进行了研究,主要做的工作有以下几方面:(1)阐述了无线传感器网络的相关概念,如无线传感器网络的特点、体系结构等。重点介绍了无线传感器路由协议,并详细介绍了AOMDV协议和LEACH
2、协议。通过对AOMDV协议与AODV协议进行仿真对比,分析了AOMDV协议的平均延时、分组投递率、吞吐量等性能,同时也对LEACH协议在节能方面进行了分析。(2)介绍了无线传感器网络的MAC层协议,详细分析了SMAC协议,并与802.11协议比较,分析两种协议消耗能量、平均延时等性能,最后对SMAC协议作出总结。(3)本文最后对所有工作做了总结,并进一步展望了无线传感器网络的发展方向和未来。【关键词】无线传感器网络;路由协议;能量消耗;平均时延39Abstract【Abstract】Withtherapidd
