“…Social reciprocity is a powerful mechanism to facilitate mutual beneficial cooperation in the absence of social trust, which does not need a strong social connection between two users 26 . For example, when D2D users have no friends in the network, they may help nearby strangers to improve the network performance by providing relay assistance or other services; then, they may also get help due to the mutual psychology of strangers.…”

“…But the reciprocal relationship described in Li et al 27 ignores temporal characteristics such as the reciprocity interval between users. Generally, in a given time, the shorter the reciprocity interval, the higher the trust between two users 26 . Considering the reciprocity interval, we define the trust relation of social reciprocity between two users as

R_{i, j}^{t} = ({, \begin{array}{l} \frac{2}{π} arccot \overset{t_{i, j}^{circle}}{true}, & direct or indirect mutual aid, \\ 0, & other, \end{array})

where

\overset{t_{i, j}^{circle}}{true}

represents the average reciprocity interval between two users.…”

Content sharing via device-to-device (D2D) communications has become a promising method to increase system throughput and reduce traffic load. Due to the characteristic of spectrum sharing in D2D network, confidentiality is becoming a key issue in content transmission. Secure communication in D2D networks is generally guaranteed by a physical-layer security mechanism. However, this method sacrifices the system transmission rate while ensuring security. Since mobile devices are carried by humans, we can leverage their trust relations to enhance the security of communications. As much, considering the psychology structure and social attributes of mobile users, we build a multidimensional trust evaluation mechanism to evaluate the trust relationship between users, and we pick out the trusted users based on the decisiontheoretic rough sets. By sharing content only between trust users, we can enhance the security of content transmissions without relying on physicallayer security measures. Meanwhile, content caching is now widely used to improve accessing efficiency and reduce traffic load on cellular networks. However, caching content for other users incurs additional cost, which results in selfish and noncooperative behavior in users. Considering such selfishness, we introduce a cooperative caching game based on multidimensional trust relations to motivate users to cache contents for other devices. In this game, the trust relations and physical distance between two users are considered to formulate the cost function. Furthermore, we introduce an incentive caching algorithm based on social trust to minimize the total cost in the D2D network.

“…On the other hand, ensuring satisfactory services become even more challenging when the end-users are located at large distances from the transmit source. In this vein, cooperative relaying has emerged as useful means to assist a transmitter to communicate with the intended receiver by guaranteeing an improved coverage and appreciable overall throughput [1], [2].…”

In this paper, we investigate resource allocation and relay selection in a dual-hop orthogonal frequency division multiplexing (OFDM)-based multi-user network where amplifyand-forward (AF) enabled relays facilitate simultaneous wireless information and power transfer (SWIPT) to the end-users. In this context, we address an optimization problem to maximize the end-users' sum-rate subjected to transmit power and harvested energy constraints. Furthermore, the problem is formulated for both time-switching (TS) and power-splitting (PS) SWIPT schemes. We aim at optimizing the users' SWIPT splitting factors as well as sub-carrier-destination assignment, sub-carrier pairing, and relay-destination coupling metrics. This kind of joint evaluation is combinatorial in nature with non-linear structure involving mixed-integer programming. In this vein, we propose a sub-optimal low complex sequential resource distribution (SRD) method to solve the aforementioned problem. The performance of the proposed SRD technique is compared with a semi-random resource allocation and relay selection approach. Simulation results reveal the benefits of the proposed design under several parameter values with various operating conditions to illustrate the efficiency of SWIPT schemes for the proposed techniques.

“…At present, IoT applications include, e.g., smart grids and cities, wireless sensors, internet of vehicles, and so on. In such applications, IoT devices (e.g., smartphones, vehicles) often are utilized as the sink nodes to assist sensing data collection in the manner of end to end communication technology, such as device-to-device (D2D) and machine-to-machine (M2M) communications [2][3][4][5]. As the IoT devices and their applications increase tremendously, mobile data services are also growing rapidly.…”

To satisfy the rapidly growing requirements of wireless data services recently, fog computing which is as an extension of cloud computing is proposed for offloading the Internet of Things (IoT) data services and applications. It depends more on the collaboration of near-located devices, instead of sending the information to remote servers. In this paper, we conceive the idea of utilizing device-to-device (D2D) communications as the infrastructures for computation and communication. In particular, D2D communication technology is one of the most important and innovative revolutions in the development of future cellular networks, which greatly enlarges the system capacity and extensively enriches the service category and application diversity. In computation part, by analyzing the interest difference of users, a Virtual Fog Community (VFC) is established in this paper, which exploits the coalition game based on the transfer effectiveness to adaptively divide users into multiple fog communities. In communication part, by perceiving the importance degrees of users and accordingly employing multidimensional network status parameters such as the local centrality and closeness degree, the best cooperative user can be reasonably selected based on the physical and social attributes of users. Therefore, the corresponding inter-community and intra-community D2D cooperative transmission mechanisms are devised to dramatically optimize the network resource utilization. Simulation results show that the proposed mechanism fully exploits the social relationship between users and effectively enhances the network operational efficiency at the cost of relatively low delay.
