Securing Link State Routing for Wireless Networks against Byzantine Attacks: A Monitoring Approach

Byzantine attacks are constant threats in many applications such as disaster management, and battlefield applications. In this paper, we introduce a monitoring scheme in the link state routing protocol to secure the packets' route against Byzantine attacks. The goal of our proposed scheme is to guarantee communication among connected benign nodes in the network. Specifically, each node monitors the action of neighboring nodes and compares the optimal packet route against the packet route history. Also, our scheme uses a statistical method to know if a node is dropping packets intentionally by analyzing the packet dropping behavior of each node. The proposed scheme provides protection against colluding attacks and other Byzantine attacks.
