摘 要
无线传感器网络是计算机科学技术的新研究领域，是传感器技术、嵌入式计算技术、分布式信息处理技术和无线通信技术相结合的产物。与传统网络相比，无线传感器网络具有成本低、功耗低、布局灵活性强、监控精度高等特点，在军事、医疗、家庭等领域具有广阔的应用市场。
基于无线传感器网络的洪水路由协议，无线传感器网络节点数量庞大，单个节点资源有限。路由协议设计的主要目标是提高能量有效性，延长网络寿命。本文总结了WSN分析了概念、结构和特征WSN关键技术问题术问题和网络协议；WSN分析比较了国内外学者提出的几种具有代表性的路由协议及其性能优缺点；选择了flooding根据传感器节点能量和传输范围有限等特点，分析了路由算法的具体实现情况，提出了一种基于延迟的自适应洪水路由算法。首先，路由是通过源节点在网络中使用较小的路由请求报告和路由回复报告来建立的。在路由建立过程中，自适应地确定等待时间，以转发更好的路由请求报告，然后源节点沿建立的路径转发较大的数据报告。并采用MATLAB网络模拟工具对路由协议进行了整体模拟，并对其数据进行了分析。并采用MATLAB网络模拟工具对路由协议进行了整体模拟，并对其数据进行了分析。模拟实验表明，新算法比较Flooding节能，能更好地克服Flooding报文冗余度高，能耗能耗大等不足。

Abstract
Wireless sensor networks are a new research field of computer science and technology. They are the integration of sensor techniques, nested computation techniques, distributed computation techniques and wireless communication techniques. Comparing with traditional networks, the wireless sensor networks features with low cost, low power loss, flexible layout and high monitor precision, therefore the sensor networks can be used for various application are as such as military, chemical, home.
This article focus on wireless sensor networks based on the Pan Hung-routing protocol, wireless sensor network nodes large number of individual nodes with limited resources, the routing protocol designed first and foremost objective is to improve energy efficiency and extend the network lifetime. This paper summarizes the WSN the concept, structure and characteristics of the WSN the key technical problems and network protocols; study of the WSN system and network routing protocol agreement the classification, analysis and comparison of the current domestic and foreign scholars have proposed several representatives The routing of the agreement and its performance advantages and disadvantages; chosen the flooding focus on routing protocols, analysis of the routing algorithm to achieve the specific, the sensor nodes the limited scope of energy and transmission characteristics, a delay bas
