摘要

虚拟多输入多输出是一种行之有效的降低无线传感器网络能耗的技术，但它不能解决无线传感器网络的能效问题。在高节点密度的WSN中，传感器节点向汇聚节点传递相关信息，降低了WSN的能量效率。为了提高无线传感器网络的能量利用率，提出了基于虚拟MIMO的分布式源编码方法。在DSC-MIMO中，DSC在发送到虚拟MIMO链路之前压缩从传感器节点传输的冗余数据。仿真结果表明，在不同传输距离下，分布式源编码可以最大限度地降低传感器网络的能量消耗，提高传感器网络的能量效率。仿真结果还表明，在一定范围内，DSC-MIMO可以使无线传感器网络的数据速率提高，从而降低每比特的能量消耗。

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.
