Cross-layer Analysis for Detecting Wireless MisbehaviorTweetSpeaker: Anand Patwardhan Start: Wednesday, October 19, 2005, 10:30AM End: Wednesday, October 19, 2005, 12:00PM Location: ITE 325 Abstract: Intrusion Detections
Systems(IDSs) in ad hoc networks monitor other devices for
intentional deviation from protocol, i.e., misbehavior. This process
is complicated due
to limited radio range and mobility of nodes. Unlike conventional
IDSs, it is not
possible to monitor nodes for long durations. As a result IDSs suffer from
a large number of false positives. Moreover other environmental conditions like
radio interference and congestion increase false positives,
complicating classification
of legitimate nodes and attackers.
We present a scheme that helps in accurate diagnosis of malicious
attacks in ad hoc
networks. Our scheme employs cross-layer interactions based on
observations at various
networking layers to decrease the number of false positives. Our
simulations show
that our scheme is more effective and accurate than those based on
isolated observations
from any single layer. Tags: cross-layer analysis, intrusion detection, manet Part of: Assertions:
