Energy Efficient Estimation of Gaussian Sources over Inhomogeneous Gaussian MAC Channels
In this paper, we first provide a joint source and channel coding (JSCC) approach in estimating Gaussian sources over Gaussian MAC channels, as well as its sufficient and necessary...

On the optimal performance in asymmetric gaussian wireless sensor networks with fading
We study the estimation of a Gaussian source by a Gaussian wireless sensor network (WSN) where L distributed sensors transmit noisy observations of the source through a fading Gau...

Energy efficient lossy transmission over sensor networks with feedback
The energy-distortion function (E(D)) for a network is defined as the minimum total energy required to achieve a target distortion D at the receiver without putting any restricti...
