Decentralized Resource Allocation for Multicast D2D Communications Using Stochastic Geometry

In this paper, we discuss on the device-to-device (D2D) communication to fulfill the exponentially growing demands of the high data rate services. Multicast D2D communication is envisioned as a promising solution due to its advantages of high data rates and high spectrum efficiency. However, integrating D2D communication severely degrades the quality of service (QoS) of the network. To improve the QoS, we formulate a self-organizing resource allocation scheme using a stochastic algorithm for multicast D2D communication. Using the proposed algorithm, each uplink cellular resource can be simultaneously reused by the active D2D users in a network. Theoretical analysis and simulation results validate the proposed scheme.
