“…Considering a small cell with dense users [22], [43], all the users are homogeneous PPP distributed in an area with a radius of 100 m, and the effective transmission distance between the SBS and users is set to 50m, i.e., R = 50 m. Assume that the D2D communication range is set to no more than 10m, i.e., R D2D ≤ 10 m. Meanwhile, we assume that the total number of video files is N = 100, and the number of different video files to be cached at the D2D transmitters is m = 15.…”

“…Consequently, SBSs with caching cannot satisfy the transmission rate of all the devices simultaneously, especially the edge users [1], [21]. Thus, D2D communications can be utilized at the edge of the small cells, which enables two close users to exchange data directly without the help of SBSs [22]- [25]. For the D2D communications of cellular networks, they can be divided into underlay and overlay modes [26]- [28].…”

Small-cell network is a promising solution to high video traffic. However, with the increasing number of devices, it cannot meet the requirements from all users. Thus, we propose a caching device-to-device (D2D) scheme for small-cell networks, in which caching placement and D2D establishment are combined. In this scheme, a limited cache is equipped at each user, and the popular files can be prefetched at the local cache during off-peak period. Thus, dense D2D connections can be established during peak time aided by these cached users, which will reduce the backhaul pressure significantly. To do this, first, an optimal caching scheme is formulated according to the popularity to maximize the total offloading probability of the D2D system. Thus, most edge users can obtain their required video files from the caches at users nearby, instead from the small-cell base station. Then, the sum rate of D2D links is analyzed in different signal-to-noise ratio (SNR) regions. Furthermore, to maximize the throughput of D2D links with low complexity, three D2Dlink scheduling schemes are proposed with the help of bipartite graph theory and Kuhn-Munkres algorithm for low, high and medium SNRs, respectively. Simulation results are presented to show the effectiveness of the proposed scheme.

“…The eNBs which shares channels in both uplink (UL) and downlink (DL) phases are contrived by the interference. Hence channel assignment and power control algorithms place an important role to mitigate interference problem in D2D communication [13]. The throughput and channel capacity can be increased by controlling the transmission power of all eNBs and CUs in LTE-A networks [15].…”

Interference and Mobility management are the main parameters which affect the signal capacity and reduce the transmission efficiency for D2D communication in LTE-A networks. When the users are in the same spectrum, due to the coexistence of D2D pairs and cellular users interference management becomes a critical issue. In this paper, we introduce an interference management algorithm that maximizes the performance of D2D communication in LTE-A networks for both uplink and downlink transmissions. Optimal routing selection techniques reduce the total path distance which helps to minimize the interference and improve the overall network capacity. Mobility management is also a challenging issue in IP-mobile networks. When two DUEs change their locations from one BS to the other, handover delay calculation becomes very important to maintain the communication without interruption. In this paper we show power control techniques which helps to reduce the effect of interference and also we addressed a method for the lower delay under complex mobility issues with uninterrupted D2D communication.

“…In [1], the aim of controlling and limiting the interference of a D2D communication to the cellular network was investigated. There are basically two extensive categories of power control in D2D underlaying cellular networks which include distributed [8,9] and centralized approaches [10,11]. In the distributed approach resource allocation and power control are performed independently by the UEs, whereas they are both carried out at the BS in the centralized approach.…”
