Abstract: 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 fault-tolerance 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.

Key words: Wireless Sensor Network (WSN), network coding, clustering, link failure tolerance
