“…The proposed scheme achieved a higher sum rate and lower computational complexity. However, it needs a global CSI of all DUs at the BS, which imposes a huge overhead. Integer linear program (ILP) 116 : Jaafar et al 116 investigated caching and channel allocation for content delivery network in D2D assisted HetNets. The 5G‐based HetNets are incorporated due to its advantage to alleviate the traffic burden from the BS and to make the content delivery faster.…”

Summary Device‐to‐device (D2D) communication is an emanating and robust technology for next‐generation wireless networks. It aims to minimize load from the centralized base station (BS) and lets the device communicate directly in the presence or absence of it. Further, to increase the spectral efficiency, it operates in an underlay mode, where D2D devices/users reuse the spectrum of cellular users (CUs), resulting in unusual intercell/intracell interferences. Managing resources efficiently can drastically reduce the effect of interference but on the cost of high energy consumption. The research community is diligently studying the optimal methods for energy‐efficient resource allocation in D2D systems. As per the literature, there exists no comprehensive survey that studied the existing energy‐efficient resource allocation schemes in the D2D environment. Motivated from this, we present a survey on recently adopted solutions for energy‐efficient power, channel, and spectrum allocation in D2D communication, which includes artificial intelligence (AI), optimization, dynamic programming, heuristic approach, game theory, and graph models. In addition, we also highlighted the open research issues and technical challenges while allocating resources to D2D users (DUs).

“…Consequently, power conservation and reduction in latency was achieved. In [8], the authors focused on joint optimization of data caching and channel allocation. The authors proposed a two-step heuristic scheme to perform channel allocation in the first stage and data caching in the second stage.…”

Mobility-Aware Data Caching to Improve D2D Communications in Heterogeneous Networks

et al. 2022

User Equipment (UE) is equipped with limited cache resources that can be utilized to offload data traffic through device-to-device (D2D) communications. Data caching at a UE level has the potential to significantly alleviate data traffic burden from the backhaul link. Moreover, in wireless networks, users exhibit mobility that poses serious challenges to successful data transmission via D2D communications due to intermittent connectivity among users. Users’ mobility can be exploited to efficiently cache contents by observing connectivity patterns among users. Therefore, it is crucial to develop an efficient data caching mechanism for UE while taking into account users’ mobility patterns. In this work, we propose a mobility-aware data caching approach to enhance data offloading via D2D communication. First, we model users’ connectivity patterns. Then, contents are cached in UE’ cache resources based on users’ data preferences. In addition, we also take into account signal-to-interference and noise ratio (SINR) requirements of the users. Hence, our proposed caching mechanism exploits connectivity patterns of users to perform data placement based on users’ own demands and neighboring users to enhance data offloading via cache resources. We performed extensive simulations to investigate the performance of our proposed mobility-aware data caching mechanism. The performance of our proposed caching mechanism is compared to most deployed data caching mechanisms, while taking into account the dynamic nature of the wireless channel and the interference experienced by the users. From the obtained results, it is evident that our proposed approach achieves 14%, 16%, and 11% higher data offloading gain than the least frequently used, the Zipf-based probabilistic, and the random caching schemes in case of an increasing number of users, cache capacity, and number of contents, respectively. Moreover, we also analyzed cache hit rates, and our proposed scheme achieves 8% and 5% higher cache hit rate than the least frequently used, the Zipf-based probabilistic, and the random caching schemes in case of an increasing number of contents and cache capacity, respectively. Hence, our proposed caching mechanism brings significant improvement in data sharing via D2D communications.
