由于普适移动通信和快速增长的在线社交网络的融合，移动社交网络正在渗透到我们的日常生活中。为了系统地了解社会结构和移动通信之间的相互作用，本文利用人类社会网络中的社会联系来加强设备到设备的协作通信。具体地说，由于手持设备是由人类携带的，我们利用两个关键的社会现象，即社会信任和社会互惠，促进设备之间的有效合作。基于这一认识，我们开发了一个联盟博弈论框架来设计基于社会纽带的设备到设备通信的合作策略。我们还开发了一种网络辅助的中继选择机制来实现联盟博弈的解决方案，并证明了该机制不受群体偏差的影响，个体理性和真实。我们使用真实的社会数据踪迹来评估该机制的性能。数值结果表明，与没有D2D协作的情况相比，所提出的机制可以获得高达122%的性能提升。
Thanks to the convergence of pervasive mobile communications and fast-growing online social networking, mobile social networking is penetrating into our everyday life. Aiming to develop a systematic understanding of the interplay between social structure and mobile communications, in this paper we exploit social ties in human social networks to enhance cooperative device-to-device communications. Specifically, as hand-held devices are carried by human beings, we leverage two key social phenomena, namely social trust and social reciprocity, to promote efficient cooperation among devices. With this insight, we develop a coalitional game theoretic framework to devise social-tie based cooperation strategies for device-to-device communications. We also develop a network assisted relay selection mechanism to implement the coalitional game solution, and show that the mechanism is immune to group deviations, individually rational, and truthful. We evaluate the performance of the mechanism by using real social data traces. Numerical results show that the proposed mechanism can achieve up-to 122% performance gain over the case without D2D cooperation.
