Complex network-based growth and evolution model for Internet of Things

Currently, there are lacks of relational networks consistent with the characteristics of IOT (Internet of Things). According this situation, this paper proposes a GEM model based on the analyses of the popular IoT theories and the corresponding modeling methods as well as the newest applications of the complex network theory. First, we establish an original growth model, then the model is modified and optimized according to some special characteristics of the practical IoT in terms of preferential attachment, communication difficulty and weighted connection. At last, simulation of the model proposed by this article indicates that this model yields the power-law distribution, strength of interactions and shows a good performance of community structure, which conforms to the development law of IoT.
