Enhance device-to-device communication with social awareness: a belief-based stable marriage game framework

By allowing each UE or network service provider to access the information of social networks, socially aware D2D communication has been introduced recently as a new paradigm to improve the performance of D2D communication. One of the key technical challenges for socially aware D2D communication is to convert the social relationship among UEs into the information that is useful for the decision making processes of the corresponding physical D2D communication system. In this article, we propose a novel framework referred to as belief-based stable marriage game to analyze socially aware D2D communication. In this framework, each UE can establish a belief function about its social relationship with others and use this belief function to develop a socially aware preference over all possible actions. We first review existing D2D communication strategies and discuss the issues and strategies that will be involved in the enhancement of D2D communication using social networks. We then introduce the concept of the belief-based stable marriage game and consider the spectrum sharing problem for in-band socially aware D2D communication as an example to demonstrate how to apply the proposed framework to optimize a socially aware D2D communication system. We present numerical results to verify the performance improvement brought by our proposed framework. We also outline some potential research directions and extensions.
