“…Scenarios where services are enabled by the occurrence of direct (and automated) interactions among "things" represent one of the most interesting opportunities for the 5G Device-to-Device technology. Indeed, such scenarios allow alleviating the traffic load from base stations by taking advantage of the proximity among devices, which not only contributes to improve parameters such as throughput, latency and power usage, but also increases the overall capacity of the network [7] and its reliability.…”

The imminent pervasive adoption of vehicular communication, either localized (ETSI ITS G5, IEEE WAVE or cellular D2D), long range (5G) or hybrid, will foster a richer service ecosystem for vehicular applications. The appearance of new cryptography-based solutions envisaging digital identity and currency exchange are set to stem new approaches for existing and future challenges. This paper presents a novel tolling architecture that harnesses the availability of 5G C-V2X connectivity for open road tolling using smartphones, IOTA as the digital currency, and Hyperledger Indy for identity validation. An experimental feasibility analysis is used to validate the proposed architecture for secure, private, and convenient electronic toll payment.

The imminent pervasive adoption of vehicular communication, based on dedicated short-range technology (ETSI ITS G5 or IEEE WAVE), 5G, or both, will foster a richer service ecosystem for vehicular applications. The appearance of new cryptography based solutions envisaging digital identity and currency exchange are set to stem new approaches for existing and future challenges. This paper presents a novel tolling architecture that harnesses the availability of 5G C-V2X connectivity for open road tolling using smartphones, IOTA as the digital currency and Hyperledger Indy for identity validation. An experimental feasibility analysis is used to validate the proposed architecture for secure, private and convenient electronic toll payment.

“…This problem was transformed into a SOOP via the epsilon method, and a two-stage iterative solution was proposed. Furthermore, in [15], a multiobjective cell association optimization for arranging several D2D links in a multi-cell network based on the fractional frequency reuse scheme was considered. However, because of the interference experienced by DUs in each cell, and also the effect of the received interfering power from CUs on the DUs' achievable rate, a non-trivial tradeoff between DUs and CUs would be expected.…”

“…Contrary to [2]- [9], [14], [15], we investigate in this paper the performance tradeoff between DUs and CUs in OFDMA D2D networks underlaying CUs, by optimizing the EE and throughput using a MOOP. This performance tradeoff can enhance the load balancing between DUs and CUs.…”

Optimal Multi-Objective Resource Allocation for D2D Underlaying Cellular Networks in Uplink Communications

et al. 2021

In this paper, we study a resource allocation problem in orthogonal frequency division multiple access (OFDMA)-based Device-to-Device (D2D) communications. To this end, we propose a multi-objective optimization problem (MOOP) framework, which jointly maximizes the sum rate of D2D users (DUs) and cellular users (CUs) in uplink communications and minimizes the total transmit power. The proposed problem formulation takes into account the minimum data-rates and the maximum transmitted power budget for both DUs and CUs. We transform this MOOP into a single-objective optimization problem (SOOP) using the weighted sum method and then propose an approach to solve this SOOP via a monotonic approach yielding an efficient optimal solution. Furthermore, a suboptimal solution based on the successive convex approximation (SCA) is presented to compromise complexity and performance gain. This is done to reveal that the proposed suboptimal solution closely approaches an optimal solution through simulation analysis. Numerical results unveil an interesting tradeoff between D2Ds CUs and demonstrate the superiority of our proposed solution compared to other baseline schemes.
