摘 要

无线传感器网络(Wireless Sensor Network，WSN)作为人与自然界进行信息沟通的一种方式，随着目前传感器节点小型化、多样化的发展，正得到越来越广泛的使用，人们对无线传感器网络各方面的研究也成为目前学术界的研究热点。路由协议是无线传感器网络在网络层上的一个关键研究课题，本文着重研究基于路由表的目的序列距离矢量路由协议。

本文在阐述无线传感器网络概念和特点的基础上，引入了无线传感器网络路由，介绍了现有无线传感器网络路由协议，并结合现有无线传感器网络路由协议，实现了一种基于路由表驱动的路由协议(DSDV)。本文详细分析了DSDV路由协议，实现了DSDV路由协议在NS2上的仿真，对在仿真过程中得到的数据进行分析，从中发现网络拓扑和找到路由路径，并对结果加以分析，进一步深化对DSDV路由协议的认识和了解。

ABSTRACT

Wireless sensor network(WSN)is a way that people communicate with nature. Along with the development of the sensor technology，The sensor is now miniaturization and diver- sification. It is being more and more widely used. More attention has been paid to WSN and the research on eaeh aspect of WSN is also an active field in current aeademe. Routing prot- ocol is a key issue on network layer inWSN. This thesis mainly focuses on Destination-Seq- ueneed Distanee-Veetor(DSDV) routing protocol based on routing table.

This thesis describes the concept of WSN on the basis of the characteristics of the introduction of WSN routing，and generally introduces of the existing WSN routing protocol and achieves a routing protocol based on the kinds of routing table-driven in conjunction with existing WSN routing protocols (DSDV). This thesis anlysizes the DSDV routing protocol in detail, and realized simulation of DSDV routing protocols in NS2, and analysis of the data produced during simulation, then to find the routing path. After that, we analysis the results and results to furtherly deepen our understanding of DSDV routing protocols.
