摘要无线传感器网络（Wireless Sensor Networks, WSNs）是一种新兴的技术。如今，伴随着无线传感网的发展和产业化，其安全问题备受关注，安全性是无线传感器网络面对的主要挑战之一。由于传感器节点大多部署在无人值守的环境中，因而传感器网络更容易受到各种潜在的攻击。一旦安全受到威胁，可能会带来严重的后果，比如信息窃取、隐私泄露。有效防御这些攻击，降低攻击对传感器网络造成的破坏和影响，是维护传感器网络安全的重要手段。60138

本文设计了一个仿真系统，实现了无线传感网中典型的三种攻击模型：黑洞攻击、选择性转发攻击和节点复制攻击，并实现了相应的检测和防御方法。该仿真平台很好地解决了现有的一些仿真平台操作不便、可扩展性差、没有图形界面的问题，可以很方便地设置实验参数，观察到中间过程，产生统计结果。本平台不依赖于具体的操作系统，且易于扩展。

Title   Design and Realization of Typical Wireless Sensor    Network Attack and Defense Simulation System          

Abstract

Wireless sensor networks is an emerging technology. Now, with the development and industrialization of the wireless sensor network, the security concerns. Security is one of the major challenges faced by the wireless sensor networks. Since most of the sensor nodes are deployed in unattended environments, the sensor network is more vulnerable to a variety of potential attacks, causing serious consequences, such as theft or loss of privacy. Effective defense against these attacks and reducing the damage caused by the attacks on sensor networks is an important means to maintain the sensor network security. 

This paper presents several kinds of typical attack and defenses：black hole attacks, selective forwarding attacks and node replication attacks.The simulation platform is designed to solve some of the existing problems,such as inconvenience, scalability, no graphical interface.You can easily set up an experiment parameters to produce statistical results.The platform does not depend on the specific operating system, and is easy to expand.
