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.
