Optimized Sensor Collaboration for Estimation of Temporally Correlated Parameters
Sijia Liu, Swarnendu Kar, Makan Fardad +1
In this paper, we aim to design the optimal sensor collaboration strategy for the estimation of time-varying parameters, where collaboration refers to the act of sharing measuremen…
Controlled Collaboration for Linear Coherent Estimation in Wireless Sensor Networks
Swarnendu Kar, Pramod K. Varshney
We consider a wireless sensor network consisting of multiple nodes that are coordinated by a fusion center (FC) in order to estimate a common signal of interest. In addition to bei…
Linear Coherent Estimation with Spatial Collaboration
Swarnendu Kar, Pramod K. Varshney
A power constrained sensor network that consists of multiple sensor nodes and a fusion center (FC) is considered, where the goal is to estimate a random parameter of interest. In c…
Cramér-Rao Bounds for Polynomial Signal Estimation using Sensors with AR(1) Drift
Swarnendu Kar, Pramod K. Varshney, Marimuthu Palaniswami
We seek to characterize the estimation performance of a sensor network where the individual sensors exhibit the phenomenon of drift, i.e., a gradual change of the bias. Though esti…
Spatial Whitening Framework for Distributed Estimation
Swarnendu Kar, Pramod K. Varshney, Hao Chen
Designing resource allocation strategies for power constrained sensor network in the presence of correlated data often gives rise to intractable problem formulations. In such situa…
Optimal Identical Binary Quantizer Design for Distributed Estimation
Swarnendu Kar, Hao Chen, Pramod K. Varshney
We consider the design of identical one-bit probabilistic quantizers for distributed estimation in sensor networks. We assume the parameter-range to be finite and known and use the…
