DESCRIPTION
Disruption Tolerant Networks (DTNs) utilize the mobility of nodes and the opportunistic contacts among nodes for data communications. Due to the limitation in network resources such as contact opportunity and buffer space, DTNs are vulnerable to flood attacks in which attackers send as many packets or packet replicas as possible to the network, in order to deplete or overuse the limited network resources. In this paper, we employ rate limiting to defend against flood attacks in DTNs, such that each node has a limit over the number of packets that it can generate in each time interval and a limit over the number of replicas that it can generate for each packet. We propose a distributed scheme to detect if a node has violated its rate limits.

To Lie or to Comply: Defending against Flood Attacks in Disruption Tolerant Networks
ABSTRACT
Disruption Tolerant Networks (DTNs) utilize the mobility of nodes and the
opportunistic contacts among nodes for data communications. Due to the limitation in
network resources such as contact opportunity and buffer space, DTNs are vulnerable
to flood attacks in which attackers send as many packets or packet replicas as possible
to the network, in order to deplete or overuse the limited network resources. In this
paper, we employ rate limiting to defend against flood attacks in DTNs, such that each
node has a limit over the number of packets that it can generate in each time interval
and a limit over the number of replicas that it can generate for each packet. We propose
a distributed scheme to detect if a node has violated its rate limits. To address the
challenge that it is difficult to count all the packets or replicas sent by a node due to lack
of communication infrastructure, our detection adopts claim-carry-and check: each
node itself counts the number of packets or replicas that it has sent and claims the count
to other nodes; the receiving nodes carry the claims when they move, and cross-check if
their carried claims are inconsistent when they contact. The claim structure uses the
pigeonhole principle to guarantee that an attacker will make inconsistent claims which
may lead to detection. We provide rigorous analysis on the probability of detection, and
evaluate the effectiveness and efficiency of our scheme with extensive trace driven
simulations.

What is IEEE?
The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is Incorporated in the State of New York, United States. It was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884). A membership organization comprised of engineers, scientists and students that sets standards for computers and communications. It is a nonprofit organization with more than 365,000 members in around 150 countries.
The IEEE describes itself as "the world's largest technical professional society -- promoting the development and application of electro technology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-being of our members."
Why IEEE based projects?
It grantees for standard
It assured latest solution for problems
It delivers new patented technologies at an ever-increasing pace
It access world-class technical information provided by the IEEE and cut down your
research time.
