Sensor Selection and Power Allocation via Maximizing Bayesian Fisher Information for Distributed Vector Estimation
Mojtaba Shirazi, Alireza Sani, Azadeh Vosoughi
In this paper we study the problem of distributed estimation of a Gaussian vector with linear observation model in a wireless sensor network (WSN) consisting of K sensors that tran…
On the Combined Effect of Directional Antennas and Imperfect Spectrum Sensing upon Ergodic Capacity of Cognitive Radio Systems
Hassan Yazdani, Azadeh Vosoughi
We consider a cognitive radio system, consisting of a primary transmitter (PUtx), a primary receiver (PUrx), a secondary transmitter (SUtx), and a secondary receiver (SUrx). The se…
On Power Allocation for Distributed Detection with Correlated Observations and Linear Fusion
Hamid R. Ahmadi, Nahal Maleki, Azadeh Vosoughi
We consider a binary hypothesis testing problem in an inhomogeneous wireless sensor network, where a fusion center (FC) makes a global decision on the underlying hypothesis. We ass…
On Distributed Linear Estimation With Observation Model Uncertainties
Alireza Sani, Azadeh Vosoughi
We consider distributed estimation of a Gaussian source in a heterogenous bandwidth constrained sensor network, where the source is corrupted by independent multiplicative and addi…
On M-ary Distributed Detection for Power Constraint Wireless Sensor Networks
Zahra Hajibabaei, Jalil Modares, Azadeh Vosoughi
We consider a wireless sensor network (WSN), consisting of several sensors and a fusion center (FC), which is tasked with solving an M-ary hypothesis testing problem. Sensors make…
On Bayesian Fisher Information Maximization for Distributed Vector Estimation
Mojtaba Shirazi, Azadeh Vosoughi
We consider the problem of distributed estimation of a Gaussian vector with linear observation model. Each sensor makes a scalar noisy observation of the unknown vector, quantizes…
