An energy-efficient data transmission scheme based on DSC-MIMO for wireless sensor network
The Virtual MIMO scheme is a proven technique to reduce energy consumption in WSN but it cannot resolve the energy efficiency problem in WSN. In high node density WSN, sensor nodes transmitted correlated information to sink node that will decreases the energy efficiency of WSN. For enhancing the energy efficiency of WSN, we propose distributed source coding based on virtual MIMO. In DSC-MIMO, DSC compresses redundant data, transmitted from sensor nodes before sending it to virtual MIMO link. The simulation results indicate that distributed source coding can minimize the energy consumption and enhance the energy efficiency of the WSN at different transmission distances. The simulation results also show that DSC-MIMO causes to decrease energy consumption per bit for increasing data rates up to a certain range in WSN.
