无线传感网络路由策略研究(任务书,开题报告,论文12000字)
摘 要
无线传感器网络已经不在跟过去一样是一个单独的领域了,现在一直逐步发展的在各种各样的领域都有所涉及,并且在各个领域都占有非常重要的地位,尤其是学术界与工业界。它涉及到的学科众多,应用范围宽阔,并且按照目前的发展趋势,很快就有希望成为最有发展前景的网络研究技术之一。无线传感器网络的组成说复杂也不复杂,说简单也并不是很简单,它是由多个具有检测功能的传感器节点融合而成的,这些节点各有各的作用,有的是为了采集数据,有的则是具有通信和储存的功能,他们互相之间通过无线通信技术进行连接,并建立一个自组织并且多跳的网络系统,将传感器数据传播到远程处理、可视化、分析和存储系统。节点之间需要有稳定的数据传输,而如何把数据稳定的从开源节点传输到目的节点,就就需要一个良好的路由协议来完成了。选取一个良好的路由协议的有时能决定整个系统的效率和稳定,它能确保数据的高效传输和寻找最优路径。
我写这篇论文就是想要能够弄清楚路由协议在整个无线传感网络中的作用,并且还要弄清楚它是以什么样的形式在OPNET上执行仿真的,并且灵活运用已经学过的WSNs的工作原理来搞清楚OPNET仿真平台是怎么工作的。还要通过分析不同路由协议的案例,将目前人们熟知的关于无线传感网络的路由协议分出不同的类别,以便于接下来工作和学习。还要灵活运用已有知识对路由策略的原理深入了解,分析总结优缺点,用数据图像分析得出较为优秀的路由协议。我们期待一个好的无线传感网络应当是以负载均衡、路由安全、支持移动性、跨层协议优化为发展趋势。

Abstract
Wireless Sensor Network (wsn) has been paid much attention in many fields, especially in academia and industry. It involves a wide range of disciplines, applications, has been one of the most popular network research technology. Wireless Sensor Network (wsn) is composed of several monitoring sensor nodes with functions of data acquisition, communication and storage in a certain area. They form a multi-hop, self-organizing network system through wireless communication, and transmit sensor data to remote processing, visualization, analysis and storage systems. The data transmission is dependent on the reliable routing between the source node and the destination node, which is accomplished by the routing protocol. The implementation of routing process will affect the efficiency of the whole network, it can ensure the efficient transmission of data and find the optimal path.
The purpose of this paper is to study the routing protocol in Wireless Sensor Network, including how to simulate on OPNET, how to use existing knowledge to study OPNET simulation platform, and how to combine the working principle of WSNs Several classical routing protocols are used as examples to classify the existing Wireless sensor network. Make a visual topology of wireless sensor, learn how to use OPNET, deeply understand the principle of routing strategy, analyze and summarize the advantages and disadvantages, use data image analysis to get a better routing protocol. We expect a good Wireless sensor network to be load balancing, routing security, support for mobility, and cross layer protocol optimization.
