An Energy-Efficient Transmission Scheme For Wireless Sensor Network With Dsc And Virtual Mimo

Energy efficiency is one of the primary performance parameters in wireless sensor network (WSN). The data collected by neighboring nodes in the high density WSN tend to have a high correlation which is directly transmitted to the sink node (DGN) will seriously reduce the energy efficiency of wireless sensor networks. For improving the energy efficiency of high node density WSN, We introduce distributed source coding (DSC) which can compress the high correlation source data into WSN based on virtual MIMO. In the simulation results indicate that DSC can effectively reduce the energy consumption in data transmission and improve the energy efficiency of the whole WSN.
