Modeling Data Transport Capacity of Mobile Networks for Mobile Social Services

In this paper, we mainly study the data transport capacity of mobile networks for mobile social services. Specifically, mobile ad hoc social networks (MAHSNs) with infrastructure support are considered the carrier networks. In MAHSNs with infrastructure support, the underlying physical networks and the upper social relationship networks interact with each other and influence the capacity of this hybrid mobile social communication carrier network together. For the physical networks, we introduce a more practical clustered model to depict the social behavior of users. We consider a virtual home point for each mobile user. For the upper social relationship networks, we propose an improved population-based model, in which we map the home points of the mobile users into the social relationship formation, to solve the social formation problem in the mobile environment. This process comprehensively considers the clustering levels of the degree of friendship and friendship distribution. Finally, from a layered networking perspective, the geographical distribution of the social traffic sessions is analyzed to derive the capacity for social-broadcast sessions of MAHSNs with infrastructure support. The results provide deep insights into the impacts of a user' mobility pattern and social relationship formation on the capacity of MAHSNs with infrastructure support.
