With the increased popularity of Wireless Sensor Networks (WSN) and an increasing development in the research fields of Complex and Dynamical Networks (CDN) in the last decade, up to now there have been no applications or systems used both prosperities between WSN and CDN. In this paper, the author creates an improved system-Intelligent Gain System (IGS) and intends to outline the framework of IGS based on the scale-free model of CDN. In view of hardware improvements, WSN would typically be used for longer periods of time and for multiple purposes [1]. In some cases they may even undergo evolutionary development and continuous adaptation. But how to enhance networks robustness with the increasing numbers of sensor nodes, which have directly led to more and more complex in networks, was presented in recent researches on WSN. To improve the networks robustness and communicated effectiveness of IGS, the topology of IGS based on the scale-free model of Complex and Dynamical Networks was introduced. The author suggests that the assessment for IGS should include the effectiveness and robustness. It was concluded that the comprehensive design applied in both between WSN and CDN would enhance further the communicated effectiveness and the network robustness.
