Abstract: Aiming at the QoS assurance requirement of real-time network application on wireless sensor network (WSN), a WSN model based on network coding was proposed. The new model applies the network coding characteristics to the Differented Service(DiffServ) mechanism. The same type of data flows with DiffServ classifying were encoded and composed by encoding nodes before transmitting, which reduced the amount of data to be forwarded and improved the QoS performance. The QoS performance of the new model was analyzed by the stochastic network calculus theory. By numerical analysis, we conclude that our model can improve the QoS performances of an DiffServ WSN, such as delay and data backlog.
