| Abstract: | In Internet of Things( IoT),physical objects can build their own social networks. How do social networks of physical objects generate,and what characteristics do the social networks have. In order to solve these problems,according to the interaction of physical objects in IoT,this paper presents a growing social network model of physical objects and researches the attachment mechanism of the model that includes three modes,physical distance,social distance and preference.Through the simulation realizations of the model,the characteristics( e. g. degree distribution,community structure) of social network are analyzed. The model can forecast the growth of social networks of physical object in IoT and simulate social networks of physical objects in the large scale IoT. |
