Device-to-device (D2D) communication is becoming an increasingly important technology in future networks with the climbing demand for local services. For instance, resource sharing in the D2D network features ubiquitous availability, flexibility, low latency and low cost. However, these features also bring along challenges when building a satisfactory resource sharing system in the D2D network. Specifically, user mobility is one of the top concerns for designing a cooperative D2D computational resource sharing system since mutual communication may not be stably available due to user mobility. A previous endeavour has demonstrated and proven how connectivity can be incorporated into cooperative task scheduling among users in the D2D network to effectively lower average task execution time. There are doubts about whether this type of task scheduling scheme, though effective, presents fairness among users. In other words, it can be unfair for users who contribute many computational resources while receiving little when in need. In this paper, we propose a novel blockchain-based credit system that can be incorporated into the connectivity-aware task scheduling scheme to enforce fairness among users in the D2D network. Users' computational task cooperation will be recorded on the public blockchain ledger in the system as transactions, and each user's credit balance can be easily accessible from the ledger. A supernode at the base station is responsible for scheduling cooperative computational tasks based on user mobility and user credit balance. We investigated the performance of the credit system, and simulation results showed that with a minor sacrifice of average task execution time, the level of fairness can obtain a major enhancement.

“…is is problematic as most users exhibit a nomadic behavior, staying in the same location for long periods. As a result, such delayed o oading architectures require deadlines in the order of half to a couple of hours to demonstrate performance bene ts [4,18,19]. Instead, when caches are on vehicles, especially in a dense urban environment, a user will see a much larger number of caches within the same amount of time, thus virtually extending the size of the accessible local storage.…”

Densi cation through small cells and caching in base stations have been proposed to deal with the increasing demand for Internet content and the related overload on the cellular infrastructure. However, these solutions are expensive to install and maintain. Instead, using vehicles acting as mobile caches might represent an interesting alternative. In our work, we assume that users can query nearby vehicles for some time, and be redirected to the cellular infrastructure when the deadline expires. Beyond reducing costs, in such an architecture, through vehicle mobility, a user sees a much larger variety of locally accessible content within only few minutes. Unlike most of the related works on delay tolerant access, we consider the impact on the user experience by assigning di erent retrieval deadlines per content. In our paper, we provide the following contributions: (i) we model analytically such a scenario; (ii) we formulate an optimization problem to maximize the tra c o oaded while ensuring user experience guarantees; (iii) we propose a variable deadline policy; (iv) we perform realistic tracebased simulations, and we show that, even with low technology penetration rate, more than 60% of the total tra c can be o oaded which is around 20% larger compared to existing allocation policies.

Last decade has witnessed rapid development in wireless network. The traffic demand is driven by enormous application data that have high‐bandwidth requirement. From the operators perspective, device‐to‐device (D2D) communications are expected to provide an efficient way of offloading cellular traffic. Note that, in the high‐density gathering cases, the redundant traffic in the cellular infrastructure can be drastically offloaded by disseminating the duplicated content through D2D communications. According to this observation, we propose a novel social‐aware content dissemination scheme through D2D communications to effectively offload cellular traffic. We base our proposition on the inherent social aspects of user mobility, exploit three social structural metrics, namely, centrality, contact rate, and intercontact time. The contributions of this paper are two‐fold. First, we integrate the carry‐forward mechanism and multihop forwarding into our D2D content dissemination scheme to fully utilize the potential of D2D networks. Second, based on social pattern, we design a two‐stage social‐aware delay prediction scheme (SADP) to improve the D2D offloading utility gain. The two stages are decision‐making stage and content dissemination stage. Based on real trace data set, we evaluate the proposed method through opportunistic D2D communications, which utilizes the aforementioned metrics to enhance offloading performance and D2D transmission utility gain. By comparing with other two well‐known schemes, SA‐Epidemic and SA‐Prophet, it has been shown that our method is superior to them in terms of offloading ratio and message delay and can substantially enhance the content dissemination performance. Since SADP is designed based on a distributed insight, it ensures that it can be adaptive to mobile network. To that end, we also look forward to the future that SADP is a promising approach applied in the application scenario of 5G network.
