摘要： 针对在无线传感器网络中节点能量有效性较低的问题，利用分布式信源编码方法，去除冗余并压缩节点发送的数据。将分布式信源编码方法与对应网络结构相结合，提出基于簇的无线传感器网络实现分布式信源编码方法。实验结果表明，该方法能节省网络中25%~30%的能量消耗。

Abstract: In Wireless Sensor Networks(WSN), it is not energy efficient to transfer the redundant information. This paper distributes source coding which is utilized to compress the information, but the method needs the suitable network structure. The cluster based network and distributed source coding method are combined to meet the requirement of energy efficiency of WSN. Simulation results show that there is about 25%-30% less energy consumption than the conventional routing method.
