We consider a power-constrained sensor network, consisting of multiple sensor nodes and a fusion center (FC), that is deployed for the purpose of estimating a common random parameter of interest. In contrast to the distributed framework, the sensor nodes are allowed to update their individual observations by (linearly) combining observations from neighboring nodes. The updated observations are communicated to the FC using an analog amplify-and-forward modulation scheme and through a coherent…

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 is considered, and it is shown that it is always beneficial to sample as frequently as possible, despite the fact that the samples get increasingly noisy due to the power-constrained nature of the problem.

Resource Management for Distributed Estimation via Sparsity-Promoting Regularization

A sparsity-aware optimization framework is presented for the joint design of optimal sensor collaboration and selection schemes, and it is shown that the presence of sensor collaboration smooths out the observation noise, thereby improving the quality of the signal and eventual estimation performance, and there exists a trade-off between sensor selection and sensor collaboration.
