We investigate an asymmetric connections model with a dynamic network formation process, using an agent based simulation. We permit heterogeneity of agents’ value. Valuable persons seem to have many links on real social networks. We focus on this point of view, and examine whether valuable agents change the structures of the terminal networks. Simulation reveals that valuable agents diversify t...

Cellular networks are facing severe traffic overloads due to the proliferation of smart handheld devices and traffic hungry applications. This paper tries to offload the cellular network traffic through Opportunistic Communications and Social Participation formed by the short-range communication technologies in the smart phones (e.g., Wi-Fi, Bluetooth). We design an Enhanced Greedy algorithm fo...

Location sharing is a fundamental service in mobile Online Social Networks (mOSNs), which raises significant privacy concerns in recent years. Now, most location-based service applications adopt client/server architecture. In this paper, a location sharing system, named CSLocShare, is presented to provide flexible privacy-preserving location sharing with client/server architecture in mOSNs. CSL...

this study has been conducted to examine the impact of the increasing use of virtual social networks on family structure. to achieve more accurate results, the research is carried out using the mixed method (qualitative and quantitative) and to collect the required date, first, 30 married individuals active in virtual social networks were selected and interviewed. then, a questionnaire was util...

Online social networks serve as a promising platform for social eliteness and financial gain. With such a promise or dream, zombie accounts, behind which stand no real users, become prevalent. The detection of such accounts has been games of cat and mouse, with more and more sophisticated methods used by zombie account managers. In this work, we propose a new zombie account detection technique ...
