【摘要】：现阶段用户与用户、终端与大型数据中心之间通信量越来越大，传统网络架构很难满足网络通信效率和安全的高标准要求。基于传统架构的无线传感器网络（WirelessSensor Networks,WSN）同样面临两方面问题，一方面现有WSN只能部署单一路由协议，不能根据网络状况灵活改变路由策略；另一方面随着针对WSN的入侵方式越来越多样化，基于传统架构的WSN入侵检测方式较为单一，检测效果较差。 为了解决传统网络架构对WSN路由传输及安全限制的问题，本文引入了一种新型网络架构---软件定义网络（Software Defined Network, SDN），实现网络传输与逻辑控制相分离，分布式协同计算和集中式管理控制相结合，有效提高网络路由效率，降低节点能耗，提高入侵检测准确度，降低误警率。 论文所做工作如下： 1、全面总结分析了基于传统网络架构的无线传感器网络路由协议，分析了现有无线传感器路由协议的优缺点，指出了其在传统架构下面临的低效率与高能耗问题。 2、将基于OpenFlow的SDN架构引入无线传感器网络中，提出了新型的WSN架构，采用混合型路由机制，使无线传感器网络具备灵活的可编程扩展能力。通过与传统路由算法仿真对比分析，结果表明新型架构下无线传感器网络具有高效率、低能耗的优点。 3、总结分析了传统网络架构下的WSN入侵检测方案，指出了其缺陷，如受节点能量限制只能部署轻量级算法，检测机制单一，无法实现分布式与集中检测相结合，，响应机制不够灵活等。本文提出了一种基于新型架构的漏洞扫描与入侵检测相结合的方案，通过对比分析验证了新型架构下入侵检测模型的优势。
[Abstract]:At present, the communication between users and users, between terminals and large data centers is increasing, and the traditional network architecture is difficult to meet the high standards of network communication efficiency and security. Wireless sensor networks (WirelessSensor Networks,WSN) based on traditional architecture also face two problems. On the one hand, the existing WSN can only deploy a single routing protocol, and can not flexibly change routing policies according to the network conditions. On the other hand, with the diversification of intrusion modes for WSN, the traditional WSN intrusion detection method based on the traditional architecture is relatively simple, and the detection effect is poor. In order to solve the problem that traditional network architecture restricts WSN routing transmission and security, a new network architecture, software defined network (Software Defined Network, SDN), is introduced to separate network transmission from logical control. The combination of distributed cooperative computing and centralized management and control can effectively improve network routing efficiency, reduce node energy consumption, improve intrusion detection accuracy and reduce false alarm rate. The work of this paper is as follows: 1. The routing protocols of wireless sensor networks based on traditional network architecture are summarized and analyzed, and the advantages and disadvantages of existing wireless sensor routing protocols are analyzed. The problems of low efficiency and high energy consumption in traditional architecture are pointed out. Secondly, the SDN architecture based on OpenFlow is introduced into wireless sensor networks, and a new type of WSN architecture is proposed, which adopts hybrid routing mechanism. The wireless sensor network has flexible programmable expansibility. Compared with the traditional routing algorithm, the simulation results show that the wireless sensor network has the advantages of high efficiency and low energy consumption. 3. The WSN intrusion detection scheme under the traditional network architecture is summarized and analyzed. It is pointed out that, for example, limited by node energy, only lightweight algorithm can be deployed, the detection mechanism is single, the combination of distributed detection and centralized detection can not be realized, and the response mechanism is not flexible enough. In this paper, a new architecture based vulnerability scanning and intrusion detection scheme is proposed, and the advantages of the intrusion detection model under the new architecture are verified by comparison and analysis.
