Intelligent Content Sharing Based on Cooperative Crowdsensing

Mobile crowdsensing (MCS) has become a promising solution to support the location-based content sharing applications. To meet users' demand on personalized content sharing, a general region of interest (RoI) distribution model that allows each user to have its specific RoI needs to be considered. In this context, how to deal with the asymmetry of cooperation caused by different RoI distribution is of significance for achieving the full benefits of personalized content sharing. Thus motivated, we propose an intelligent content sharing scheme based on cooperative crowdsensing, which ensures both efficiency and fairness. Specifically, users' decision-making of whether to participate in MCS is cast as a MCS participation game (MPG). The game captures the impact of different RoI distributions on the collective cooperation of MCS. By computing the Nash equilibrium of MPG with desirable properties, we develop a cooperation scheme that maximizes the overall system utility and is acceptable to all users. The system efficiency of the proposed scheme is further quantified by numerical simulations over various parameters.
