Dr. Paul Cotae, Professor of Electrical and Computer Engineering has more than 25
years of experience in the communication field (research and education). He received a Dipl. Ing.
and a M.S. degrees in communication and electronic engineering in 1980 from the Technical
University of Iassy and a Ph.D. degree in telecommunications from “Politechnica” University of
Bucharest, Romania in 1991, and a Master in Applied Mathematics in 1998 from the University
of Colorado at Boulder. From 1994 to 1998 he spent four years at the University of Colorado at
Colorado Springs and the University of Colorado at Boulder as a Fulbright Scholar and Visiting
Associate Professor doing research and teaching in ECE department and APPM department. He
served also as a consultant to Navsys Corp., Colorado Springs, in 1997. From 2002 to 2008 he
was with the Department of Electrical and Computer engineering at the University of Texas at
San Antonio (UTSA). From 1984 to 2001, he was with the Department of Electrical Engineering,
Technical University of Iassy, where he conducted research and teaching in the area of digital
communications as a Full Professor at the same department. Since 2008, he has been with the
University of the District of Columbia as a Professor. His current research interests
include multiple access, modulation and coding, mobile communications, and digital
communication systems. He has authored or coauthored more than 150 papers in these areas and
four books. Dr. Cotae serves as an Associate Editor for IEEE Communication Letters, EURASIP
Journal on Signal Processing, Elsevier International Journal of Computers and Electrical
Engineering (JCEE), and he has been on the Technical Program Committee and Session chair of
the IEEE Conferences GLOBECOM (2003-2011), VTC Spring 2005, 2006 and ICC 2005-2011.
He is a Senior Member of IEEE, member of ASEE, member of HKN (Eta Kappa Nu) and SIAM.
He is cited in Who’s Who in American Education, Who’s Who in America, and in Who’s Who in
the World. He is Faculty Fellow for the ONR-ASEE Summer Faculty Research Program 2009-2018.

Abstract

In this paper, we focus on the computer network security by finding the vulnerable components of the networks which are very critical for protecting infrastructure and network system performances. In a typical attack case, an attacker would first exploit the weak elements on a network, and then he/she only needs to target some critical edges or nodes. As a case of study, we choose which nodes or edges would be attacked on a social network by using four centrality measures such as: degree, closeness, eigenvector and betweenness centrality. Our priority is to enhance the over-all network performance and to prevent undesired future attacks. We will use several types of network topology and different form of graph centrality to show the most important nodes by ranking them. We balance all the above concepts by using similar ideas as in Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) which is a Multi-Attribute Decision Making (MADM) technique focusing on node importance and asset criticality. This technique will help us to demonstrate and distinguish critical nodes which will help us the right decision for the network security.
