Social-aware peer discovery and resource allocation for device-to-device communication

Abstract

Device-to-device (D2D) communication has been regarded as a major technology to improve spectrum utilization and to offload the traffic from cellular base station. D2D peer discovery, as a critical procedure, attracts a lot of attentions. Furthermore, combination with the mobile social network (MSN) is an efficient solution to improve the establishment of D2D pairs. However, limited work has been considered about the D2D peer discovery based on MSN. In this paper, we propose an efficient D2D communication scheme for jointly considering D2D peer discovery and resource allocation. Firstly, D2D peer discovery and match mechanism is studied under a D2D communication scenario with MSN. Particularly, residual energy of nodes is taken into account from the concept of green communication. Then based on the matched results, a resource allocation problem is formulated where sub-carries and power resource are jointly allocated. Finally, simulation results are presented to verify effectiveness of our studies.
