“…Unlike conventional cellular technology that conveys information between two user equipments (UEs) via evolved NodeB (eNB), D2D communications allows UEto-UE data exchange on direct links. By relieving the eNBs from too much relaying, D2D communications improves the overall system capacity and end user data rates [3]. The idea is that the eNB shall help the two UEs in establishing a direct connection between them, and then let the communication session evolve on one-hop D2D link.…”

“…In the overlay mode, CUEs and DUEs operate at two different frequency sub-bands. While the overlay technique works best in reducing interference, it results in the underutilization of the frequency resource [3,10]. Almost all previous works on D2D communications prioritize the underlay technique because it can accommodate more UEs on a given frequency band.…”

Device-to-device (D2D) communication-enabled cellular networks allow cellular devices to directly communicate with each other without any evolved NodeB (eNB). D2D communication aims to improve the spectral efficiency and increases the overall system capacity. For future mobile networks, intelligent radio resource allocation and power control schemes are required to accommodate the increasing number of cellular devices and their growing demand of data traffic. In this paper, a combined resource allocation and power control scheme for D2D communication is proposed. In the proposed scheme, D2D communication reuses the uplink (UL) resources of conventional cellular user equipments (CUEs); therefore, we have adopted single-carrier frequency division multiple access (SC-FDMA) as UL transmission scheme. The proposed scheme uses fractional frequency reuse (FFR)-based architecture to efficiently allocate the resources and mitigate the interference between CUEs and D2D user equipments (DUEs). In order to guarantee the user fairness, the proposed scheme uses the well-known proportional fair (PF) scheduling algorithm for resource allocation. We have also proposed an intelligent power control scheme which provides equal opportunity to both CUEs and DUEs to achieve a certain minimum signal-to-interference and noise ratio (SINR) value. The performance evaluation results show that the proposed scheme significantly improves the overall cell capacity and achieves low peak-to-average power ratio (PAPR).

Abstract-The area of mobile communication is fast developing as a result of the technological advancement in the field of mobile and wireless communication. Obviously, 3G was once acclaimed as a recent technology in the field of wireless and mobile communication until the arrival of 4GLTE. The quest for a faster speed, lower latency, better QoS and ability to interoperate with all existing network are some of the factors that brought up the emergence of 4GLTE network. In this paper we provide an overview of all network generations from the first generation to the fourth generation as well as the differentiating features that supports the superiority of the 4GLTE network to the 3G network are well stated. We use self-analytical tools like bar charts to compare the features of 4GLTE and 3G networks. The concluding part of this paper presents improvements needed in 4GLTE.Index Terms-3G, 4GLTE, OFDMA, comparison of 3G and 4GLTE networks.

“…A mobile phone user with dying battery may for example refuse to contribute the scarce battery resource to D2D communications just to improve the downloading speed of others, and many users may not be pleased to devote part of the limited buffer of their mobile devices to safeguarding the interests of strangers. Unfortunately, current researches have assumed that UEs are always willing to act in a cooperative way and fail to consider the inherent selfishness of UEs in the D2D communication systems [1], [3], [5], [10], [11], which may lead to overestimation of the system performance and misinterpretation of the relevant properties. Obviously, if most users are unwilling to participate in D2D transmission, the resources cannot be utilized sufficiently, and a D2D underlaying cellular system will not able to operate successfully.…”

Abstract-In a device-to-device (D2D) communication underlaying cellular network, user equipment are required to operate cooperatively and unselfishly to transmit data as relays. However, most users more or less behave in a selfish way, which makes user selfishness a key factor that affects the performance of the whole communication system. We focus on the impact of user selfishness on D2D communications. By separating the user selfishness into two types in accordance with two D2D transmission modes, which are connected D2D transmission and opportunistic D2D transmission, we propose a time-varying graph model that characterizes the impacts of both individual and social selfishness on the D2D communications. Simulation results obtained under the realistic networking settings indicate that the interaction between connected and opportunistic selfishness worsens the impairment caused by individual selfishness. Additionally, when concerning social selfishness, inside-community selfishness can be ignored in some occasions, while otherwise its role is heavily influenced by community numbers.
