“…In particular, we consider how to efficiently use D2D communications for enhancing the quality of wireless multicast services in cellular networks. There are several other studies that address similar issues, see for instance [11], [12], [13], [5], [6]. In these papers several paradigms for multicast content delivery in LTE systems based on the joint use of cellular and short-range D2D communications have been proposed.…”

Abstract-In this paper device-to-device (D2D) communication is proposed as a tool for enhancing the services provided by mobile cellular networks. The proposed approach is tailored to mobile services with high bandwidth demands (e.g., real time streaming services). The technique we discuss relies on the cooperation among the mobile users that participate in the service delivery process, under the control of the base station. In particular, the paper proposes an incentive mechanism encouraging terminals to organize into an optimal number of clusters from the point of view of both bandwidth capacity and power saving. The aspects inducing users to collaborate are analyzed and modelled, e.g., the amount of mobile battery power drained during collaboration, to better design incentives to switch to D2D. The proposed technique allows the base station to estimate the incentives to grant to the mobile terminals to optimize its cost. Through both analysis and simulations, we show that our scheme achieves a significant gain in terms of costs while increasing the bandwidth capacity of the whole cell.
