Since wireless sensor networks have limited energy resources, energy efficiency and reliable data transmission rate are key issues in designing the topology. In this paper, a new root protocol NCQ-DD is proposed in order to solve the issue of limited performance of DD in wireless sensor networks. NCQ-DD greatly improves traditional DD protocol by utilizing random linear network coding technology and service quality perception. Experimental results show that the new routing protocol can save network bandwidth resources and sensor node's energy, improve data transmission rate and ensure reliable transmission, thus increasing the lifetime of sensor networks.
