Physical-Layer Security via Distributed Beamforming in the Presence of Adversaries with Unknown Locations
Yagiz Savas, Abolfazl Hashemi, Abraham P. Vinod +2
We study the problem of securely communicating a sequence of information bits with a client in the presence of multiple adversaries at unknown locations in the environment. We assu…
Submodular Observation Selection and Information Gathering for Quadratic Models
Abolfazl Hashemi, Mahsa Ghasemi, Haris Vikalo +1
We study the problem of selecting most informative subset of a large observation set to enable accurate estimation of unknown parameters. This problem arises in a variety of settin…
Randomized Greedy Sensor Selection: Leveraging Weak Submodularity
Abolfazl Hashemi, Mahsa Ghasemi, Haris Vikalo +1
We study the problem of estimating a random process from the observations collected by a network of sensors that operate under resource constraints. When the dynamics of the proces…
Near-Optimal Distributed Estimation for a Network of Sensing Units Operating Under Communication Constraints
Abolfazl Hashemi, Osman Fatih Kilic, Haris Vikalo
We study the problem of distributed state estimation in a network of sensing units that can exchange their measurements but the rate of communication between the units is constrain…
A Novel Scheme for Support Identification and Iterative Sampling of Bandlimited Graph Signals
Abolfazl Hashemi, Rasoul Shafipour, Haris Vikalo +1
We study the problem of sampling and reconstruction of bandlimited graph signals where the objective is to select a node subset of prescribed cardinality that ensures interpolation…
