In this paper, we address the problem of routing disruption attacks in Cognitive Radio Networks (CRNs). In routing disruption attacks, the malicious node intentionally drop data packets to consume more network resources or degrade routing performance. We propose a trust management model to mitigate such attacks in CRNs. Through monitoring forwarding behaviors of secondary users (SUs), trusts of SUs...

DTN is particularly useful for the areas in which there are no direct connection (either physical or wireless) between source and destination over a long distance, as it can overcome the...
