Denial in DTNs

Disruption-Tolerant Network (DTN) is an intermittently connected network where the traditional end-to-end data communication between a source-destination pair is hardly possible. Instead, nodes opportunistically replicate the same packet several times and try to deliver them through multiple paths. Due to this multi-copy forwarding scheme, Denial of Service (DoS) attacks in DTN is believed to be a non-trivial task. Unlike classical DoS attacks for the Internet where an attacker renders some service at a particular node unavailable for legitimate users, in DTN, attackers do not have any node-level attack objective.
