  User-behavior-aware communications will be a key feature of future generation
cellular networks, so user experience is enhanced with greater benefit to
users. In this paper, a user-behavior-aware Stackelberg (U-BeAS) game for
device-to-device (D2D) communications overlaying cellular communications is
proposed. Our proposed game provides an optimal trade-off between minimizing
transmit power and maximizing packet delivery ratio (PDR), with respect to D2D
user-behavior for all D2D pairs. The Stackelberg leader, base station (BS),
selects its satisfaction with the social welfare of the D2D followers by
considering the reaction of the followers to the price it charges. All
followers (D2D pairs) select transmit power so as to guarantee a desired
quality-of-experience (QoE), where each follower enacts one of three possible
behaviors: (i) casual; (ii) intermediate; or (iii) serious. Analysis shows that
there exists a sub-game perfect Stackelberg Equilibrium across all players.
Analysis and simulation demonstrates that the BS leader rapidly converges to an
optimal satisfaction while guaranteeing social welfare across D2D users, and
all D2D followers then rapidly converge to a Pareto-efficient outcome with
respect to transmit power and PDR.
