“…In Zhang et al, 22 a green cooperative D2D communication is designed to avoid noncooperative behavior by adopting the social‐aware cooperative D2D MAC protocol. Wu et al 23 proposed a user‐centric video transmission mechanism by considering user sharing willingness, user location distribution, and user quality of experience (QoE) requirements. These works have established some reliable D2D cooperative communication mechanisms based on objective factors rather than social factors.…”

“…When a user helps others transmit content via the D2D link, there must be a directional connection between them. Therefore, the BS can build a reciprocal relationship between two users 23 . But the reciprocal relationship described in Li et al 27 ignores temporal characteristics such as the reciprocity interval between 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.

“…In this paper, we consider the scenario in which some idle users will firstly be recruited as CH and pre-cache some popular contents in off-peak period to relieve the offloading of SBSs in the peak period [5], [6]. The CRs on task will request needed data packets from CHs, SBSs or MBS, to perform corresponding operations.…”

“…If the content delivery procedure requires downloading redundant contents repeatedly during a period, enormous pressure will be posed to the traffic load at the base stations (BSs). Intuitively, if the popular contents can be pre-stored into the intermediate nodes, known as caching, the redundant content transmission will be avoided to a certain extent [5]. In [6], the authors studied the caching in Social IoT scenario, where IoT devices can pre-cache some desired contents and share them socially with surrounding devices, which inspired us to integrate it in IIoT scenario.…”

As a new Internet of Things (IoT) paradigm where smart devices work socially by exploiting social tie with adjacent devices, the Social IoT (SIoT) can effectively meet the real-time data sharing demands in Industrial IoT (IIoT) scenario, with the inter-device social relations being incentives. Besides, precaching on device level can potentially combat the backhaul capacity bottlenecks. Considering the limited cache memory, we may not use the whole capacity for caching, but leave a fraction for buffering data packets. In this paper, we investigate how to maximize the quality of experience (QoE) while minimizing the energy consumption. Firstly, we design a proactive cache placement scheme for cost minimization. Next, we conceive the content sharing procedure with the framework of tripartite graph and propose a ternary stable matching algorithm to let devices self-organize the content sharing. Finally, we prove that inconspicuously manipulation with domino effect can further improve the system performance.

Fuzzy vault‐based three‐factor authentication and key exchange for 5G‐integrated wireless sensor networks

The integration of the wireless sensor networks (WSNs) and the advanced 5G networks has greatly enriched applications of the Internet of Things. However, the open access to sensor nodes whose resources are limited makes the entire WSNs potentially insecure. It is impending to authenticate the identities of the communication participants to prevent various attacks such as eavesdropping, capturing, and tampering. Recently, an authentication and key exchange protocol for 5G‐integrated WSNs was proposed by Shin et al. However, we have found that the scheme cannot defend against offline password guessing attacks and de‐synchronization attacks. Therefore, we put forward an enhanced authentication and key exchange protocol, which can resist known attacks and shows more fitness for the scenario of 5G‐integrated WSNs. In addition, we have analyzed that our scheme is provably secure under the random oracle model with a strict adversarial hypothesis and possesses a better performance than Shin et al's scheme.
