In this paper, the authors study the optimal differentiated subsidies from a Mobile Network Operator (MNO) to form a shared small cell network using social network information. It is a win-win strategy for the MNO to offload data and for Small cell Users (SUs) to receive enhanced QoS. They formulate the problem as a Stackelberg game: in stage I, the MNO sets differentiated subsidies and maximizes a subsidy elasticity of sharing metric, which captures the goal of using the least subsidies to obtain the most shared network; in stage II, each SU decides the degree of sharing by maximizing a utility function, which is a tradeoff between proportional-fair capacity and subsidy.
