Abstract:
Robust network operation and the ability to provide user and data
security while under attack are desirable qualities of network
protocols. However, these qualities require a fundamental understanding
of network protocol vulnerabilities and characterization of the space of
possible attacks. Understanding attacks and their impact is thus a
necessary prerequisite to the design of robust networking protocols.
Wireless ad-hoc and sensor networks present additional challenges to
robust protocol design in the form of resource and computational
constraints, reliance on the wireless medium, and the absence of
pre-existing network infrastructure. In this work, we will consider
modeling the impact of jamming attack on networks that allow multiple
path routing and contain multiple sources and destinations. We show that
by appropriate mapping, this problem can be viewed as a network flow
problem and then provide a constrained optimization formulation of the
problem.
