MANET中基于置换确认的黑洞攻击检测机制
An Effective Black Hole Attack Detection Mechanism using Permutation Based Acknowledgement in MANET
摘要：
随着无线技术的演进和移动设备的使用，移动自组织网络已经成为研究者们探讨的热点。移动自组织网络（MANET）是一种由无线链路连接的移动路由器（和相关主机）组成的自配置网络。路由器和主机可以自由地随机移动和任意地组织自己。它允许移动节点直接通信，而无需任何集中式协调器。这样的网络场景不能依赖于集中式和有组织的连接，并且可以被设想为移动Ad-Hoc网络的应用。因此，移动自组网是脆弱的，由于其动态的网络拓扑结构，因为任何节点在任何时候都变得不可信。黑洞攻击是指恶意节点利用自身的最短路径攻击任意目的地、伪造数据或进行DOS攻击的一种安全风险。在本文中，有效地检测这样的节点，我们提出了一个基于置换的确认最广泛使用的反应式协议adhoc按需距离矢量路由AODV。该机制是自适应确认（AACK）和TWO-ACK的增强，在这里，我们试图通过减少网络中路由的消息数量来显示效率的提高。
英文摘要：
With the evolution of wireless technology and use of mobile devices, Mobile Ad-hoc Network has become popular among researchers to explore. A mobile ad-hoc network (MANET) is a self-configuring network of mobile routers (and associated hosts) connected by wireless links. The routers and hosts are free to move randomly and organize themselves arbitrarily. It allows mobile nodes to communicate directly without any centralized coordinator. Such network scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of Mobile Ad-Hoc Networks. Thus, MANET is vulnerable due to its dynamic network topology, as any node become untrusted at any time. The Black hole attack is one kind of security risk in which malicious node advertises itself to have a shortest path for any destination, to forge data or for DOS attack. In this paper, to detect such nodes effectively, we propose a Permutation based Acknowledgement for most widely used reactive protocol ad-hoc on demand distance vector routing AODV. This mechanism is enhancement of Adaptive Acknowledgement (AACK) and TWO-ACK, here we have tried to show the efficiency increment by decreasing number of messages routed in the network.
