The Internet of things (IoT) has been realized as one of the most promising networking paradigms that bridges the gap between the cyber and physical world. Developing green deployment scheme for IoT is a challenging issue since IoT achieves larger scale and reaches more complex so that the most of current schemes for deploying Wireless Sensor Networks (WSNs) cannot be reused. This paper addresses this challenging issue and proposes Gemini, a Green deployment scheme for internet of Things, that emphasizes modeling and optimization on green IoT deployment. The contributions made in this paper include: (i) A hierarchical system framework for general IoT deployment. (ii) An optimization model on the basis of proposed system framework to realize the IoT toward green. And (iii) a minimal energy consumption algorithm for solving the optimization model. Through numerical experiments, the results show that the Gemini proposed in this paper can work flexibly and energy-efficiently with both deterministic and random networking settings, thus is applicable to the green IoT deployment.
