Abstract
Aiming at the bad video quality which caused by the diversity of user's cooperation willingness and the limited transmission rate of multicast due to the worst channel quality of user, a model for cooperative D2D communications that combines social relationships and physical conditions between users is proposed. The corresponding D2D pairing for cooperative video transmission algorithm based on stable matching in this model is also given. Unicast throughput is derived by considering the social relationships and wireless propagation conditions. The preference information are generated by designing the utility function of cooperation, the users form a stable matching by dynamic negotiation. Simulation results demonstrate that D2D communications can be enhanced by considering social aspects, the performance of the proposed algorithm can be improved with higher throughput compared to the traditional cooperative scheme.
