In underlay D2D communications, cellular users share resource with D2D users, which may cause severe interference. When cellular cells have light loads, overlay D2D communications can be applied to avoid interference. In this paper, we adopted overlay D2D mode under which D2D resource is orthogonal to cellular user resource. We proposed two location-based D2D resource allocation algorithms for V2V...
In this paper, we investigate the physical layer security scheme in heterogeneous Device-to-Device (D2D) and cellular networks. More specifically, we aim to optimize the secrecy capacity of D2D users in a single cell where the D2D users share downlink resource with cellular users. We assume that base station is equipped with multiple antennas while other nodes are equipped with single antenna, and...
