基于指数信任的无线传感器网络黑洞攻击检测机制

Exponential Trust Based Mechanism to Detect Black Hole attack in Wireless Sensor Network

Dr. Deepali Virmani, Manas Hemrajani, Shringarica Chandel

摘要:

安全性是无线传感器网络的一个重要特征,但无线传感器网络容易受到多种攻击,黑洞攻击就是其中之一。在黑洞攻击中,所有的数据包都被连续丢弃,这导致网络效率的降低和不必要的电池寿命浪费。在本文中,我们提出了一个指数信任的机制来检测恶意节点。在所提出的方法中,条纹计数器被部署来存储连续的数据包丢失的数量和信任因子是为每个节点维护。信任因子随着每个连续数据包的丢弃而呈指数下降,这有助于检测恶意节点。所提出的方法显示了一个节点被检测为恶意节点之前丢弃的数据包的数量急剧减少。

英文摘要:

Security is a key feature in Wireless Sensor Networks but they are prone to many kinds of attacks and one of them is Black Hole Attack. In a black hole attack all the packets are consecutively dropped which leads to the decrease in the efficiency of the network and unnecessary wastage of battery life. In this paper, we propose an exponential trust based mechanism to detect the malicious node. In the proposed method a Streak counter is deployed to store the consecutive number of packets dropped and a trust factor is maintained for each node. The trust factor drops exponentially with each consecutive packet dropped which helps in detecting the malicious node. The proposed method show a drastic decrease in the number of packets dropped before the node being detected as a malicious node.
