Abstract

Defending the data from malicious attacks is an important yet demanding security issue. In this paper, we describe clarification for such network that protects both the routing and data forwarding functions. It guards the data by detecting and reacting to the malicious nodes. Although methods have been proposed to mitigate routing misbehavior in mobile ad hoc networks, they cannot be directly applied to DTNs because of the flashing connectivity between nodes. To overcome the problem, we propose a scheme to detect packet dropping in DTNs. In our proposal, a node is required to keep a few signed contact records of its previous contacts, based on which the next contacted node can detect if the node has dropped any packet. Since unruly nodes may misreport their contact records to avoid being detected, a small part of each contact record is scattered to a certain number of witness nodes, which can collect appropriate contact records and detect the misbehaving nodes. We address a scheme to mitigate routing misbehavior by off-putting the number of packets forwarded to the misbehaving nodes. Trace-driven simulations show that our solutions are efficient and can effectively mitigate routing misbehavior.
