Energy-efficient reading of correlated wireless sensors

Abstract

The objective of this research is to design and analyze data fusion schemes for energy efficient reading of correlated wireless sensors using cooperative communications. A spatially correlated sensor network is read by a collector or fusion center using the semi-cooperative spectrum fusion (SCSF) scheme, where a cluster of sensors simultaneously transmit to the fusion center in response to a beacon transmission by the fusion center. In this research, the SCSF scheme is considered for parameter estimation and binary integration problems. The main contributions of the research are the theoretical analysis of estimation and detection performance, and energy consumption.
