无线传感器网络，应用于监测物理环境，最近出现的一个重要应用的ad hoc网络的范例。低处理能力和无线连接使这些网络容易受到各种类型的攻击。传感器的密集部署沿着协议的缺陷，使得广播攻击成为可能。针对这些类型的攻击的当前解决方案主要是加密的，并且遭受沉重的计算复杂性或缺乏移动性支持。在本文中，我们提出了一种能量有效的方法来加强传感器网络对广播攻击，使用一些关键功能，如小的传输范围和低接收灵敏度的网络。其主要思想依赖于修改当前MAC子层协议的应答时间，并在广播场景中嵌入两次或三次握手协议，以便对手从网络接收到负面反馈，以响应他在感染节点时的贪婪。仿真结果证实了该对策应用于IEEE 802.15.4的效率。
Wireless sensor networks, applied for monitoring physical environments, have recently emerged as an important application of the ad hoc networks paradigm. Low processing power and wireless connectivity make such networks vulnerable to various types of attacks. The dense deployment of sensors along with the protocol deficiencies, make broadcast attacks feasible. The current solutions for these types of attacks are mainly cryptographic and suffer from either heavy computational complexity or lack of mobility support. In this paper we propose an energy efficient method to fortify sensor networks against broadcast attacks using some key features of such networks like small transmission range and low reception-sensitivity. The main idea relies on modifying the reply timings of current MAC sub-layer protocols and embedding a two or three-way handshake protocol in broadcast scenarios so that the adversary receives a negative feedback from the network in response to his greediness in infecting nodes. The simulations confirm the efficiency of this countermeasure applied to the IEEE 802.15.4.
