Distributed Estimation in Energy-Constrained Wireless Sensor Networks
Junlin Li,Ghassan AlRegib +1 more
TL;DR: The theoretical energy-distortion performance bound for distributed estimation of a noise-corrupted deterministic parameter in energy-constrained wireless sensor networks is addressed and it is shown that the proposed algorithm is quasi-optimal within a factor 2 of the theoretical lower bound.
