摘　　要：许多紧急事件的应用对无线传感器网络的数据传输的可靠性有比较高的要求,因此对传感器网络数据传输的容错性研究十分重要。传统的1+1数据保护的容错模式带来的额外负载较大地增加了传感器节点的能耗。提出了基于网络编码的分簇结构传感器网络链路容错策略,不仅可以实现对链路的容错,而且可以降低网络中转发的数据包数量,从而降低传感器节点的能耗。In many emergent applications, Wireless Sensor Network （WSN） must be able to guarantee highly reliable data transmission, and therefore it becomes more and more important to study the fault-tolerance of data transmission faulttolerance in WSN. The 1 ＋ 1 data protection model will consumes the energy of sensor node dramatically due to its additional overload. This paper, aiming at reducing the consumption of sensor energy, proposed a scheme based on network coding in clustered WSN, which can not only achieve tolerance of link failure, but also reduce the number of data packets in network. The method has been proved to be more energy-efficient than the model of 1 ＋ 1 data protection.
