Software-Defined Networking (SDN) is a new network architecture with flexibility and scalability, researchers introduced the core idea of SDN into wireless network, and a cooperative communication system based on network coding is proposed. In this paper, we carry on an investigation in differentiated service strategy of network coding cooperative communication system. The meaning of differentiated services is for the different applications take different power for data transmission and the transmission power is associated with their reliability needs. In other words, transmission power control is performed in the presence of known reliability, we named the scheme Reliability-Bounded Transmission Power Control (RTPC) scheme. The RTPC scheme changes the way in which all the applications in the past have been able to maintain the power to be transmitted, but the reliability requirements of different applications will be transmitted with different transmission power. In addition, because of the nodes that far away from the sink node still exist a lot of energy when the network died, so consider to improve the transmission power of non-hotpots nodes in order to increase the reliability of data transmission. The experimental results show that the RTPC scheme can greatly improve the transmission reliability without affecting the network lifetime.
