Even with modern physical-layer technologies in 4G networks, the capacity of cellular networks is still insufficient enough to satisfy the insatiable appetite for bandwidth of mobile applications. Owing to the common interest among mobile users, Device-to-Device (D2D) communication has emerged as a promising solution to offload cellular traffic and enable proximity based service. While failing to provide enough incentive to encourage users may greatly affect the wide deployment of D2D communication, and sabotage the huge potential benefit it might bring to us.

Even with modern physical-layer technologies in 4G networks, the capacity of cellular networks is still insufficient enough to satisfy the insatiable appetite for bandwidth of mobile applications. Owing to the common interest among mobile users, Device-to-Device (D2D) communication has emerged as a promising solution to offload cellular traffic and enable proximity based service. While failing to provide enough incentive to encourage users may greatly affect the wide deployment of D2D communication, and sabotage the huge potential benefit it might bring to us.

In this paper, we model this content sharing as an auction game. Trading network is built between eNB and users, and auction is conducted to determine the right amount of award to encourage users, and the allocation of requests. We design a randomized auction mechanism to guarantee both system efficiency and truthfulness. Extensive experiments verify the effectiveness of our mechanism and the significant performance gain of our framework when compared with baseline methods.
