An energy-efficient cooperative MIMO transmission with data compression in wireless sensor networks

Abstract

In this letter, a novel metric for energy-efficient cooperative transmission with data compression in wireless sensor networks (WSNs) is proposed. Under the guidance of the new metric, energy consumption is optimized by considering the correlation between data generated by the sensor nodes. The distance between sensor nodes inside the cluster affecting the data correlation as a key factor is analyzed, and the corresponding optimal value is used to reduce the energy consumption.
