The position estimation in the time domain is complicated, and the time-frequency transform is first performed on the received time-domain signal to establish an equivalent frequency-domain RSS model, which simplifies the signal representation and problem solving. To realize robust VLP under limited receiving FOV, we consider the joint estimation of the receiver coordinate, light emitting diode (LED) validity indicator vector, signal phase vector and receiving coefficient based on the frequency-domain RSS vector. The original estimation problem is equivalently transformed into the optimization problem that maximizes the angle between the valid RSS modulus vector and the valid RSS feature vector. Experimental and simulation results verify the effectiveness of the proposed scheme under limited receiving FOV.

To meet Quality of Service (QoS), resource scheduling for distributed vehicle DTs is carried out. However, existing works mainly respond to service demand based on one-to-one DT synchronization and computation offloading, which limits the service response quality and is not sustainable. Meanwhile, twin objects need to be frequently transferred at edges in parallel with the moving vehicles, the IoV service demand response under high-dynamic DT resource distribution is challenging. In this paper, a novel digital twin function virtualization (DTFV) architecture based on Open Radio Access Networks (O-RAN) is proposed. In DTFV, multiple vehicle DTs following one-to-one synchronization are decoupled and reorganized as a Virtualized Digital Twin (VDT) following dissemination-based synchronization for dynamic service response, without needs for offloading service to additional edge devices. Besides, to optimize the overall IoV service response profit, we propose an asynchronous hierarchical reinforcement learning (AHRL)-based DTFV resource scheduling scheme to find optimal VDT orchestration and synchronization strategies. Finally, experimental results show our scheme achieves 8.48% higher service response profit and 6.8% lower VDT synchronization delay over the best baseline scheme.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"8 3","pages":"1049-1060"},"PeriodicalIF":5.3,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142090868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering a multiuser (MU) multiple-input single-output (MISO) broadcast channel (BC) system, we derive a generalized expression of the achievable rate for each user, in a way that the derived expression is generically applicable, e.g., for both underloaded and overloaded cases. Building upon the achievable rate expression, we formulate a multi-objective problem that maximizes the weighted sum rate (WSR) of the considered system, which incorporates with the optimization of the RS precoder for both common and private symbol streams in RSMA. The emphasis here is that our derivation of the achievable rate expression, the problem formulation of the WSR and the optimization of the RSMA precoder all involve the finite alphabet constellation constraint. An iterative gradient descent algorithm with alternative optimization and line search methods is applied to solve the optimization problem. Numerical results show that RSMA can reach the maximum achievable WSR, under both underloaded and overloaded scenarios, with less transmit power compared to the traditional schemes, e.g., space division multiple access (SDMA) and power-domain non-orthogonal multiple access (NOMA). Moreover, thanks to its flexibility, RSMA subsumes both SDMA and NOMA as its subset to fit into different scenarios such as underloaded and overloaded cases with different constellation sizes.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"8 4","pages":"1293-1307"},"PeriodicalIF":5.3,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents the critical role of BCN-SSI in the O-RAN system architecture and promises an authentication process to provide insights into the robust security measures used to seamlessly establish the identification of users and entities within the O-RAN ecosystem in the post-quantum era. We show that the integration of BCN-SSI enhances security protocols and ensures the integrity of communication networks in the evolving technological landscape. As an illustrative use case, spectrum sharing, is also presented to demonstrate the practicality and the impact of the proposed framework. Furthermore, we address the potential threats posed by quantum attacks on BCN-based SSI systems by investigating Post-Quantum Cryptography (PQC). Simulation results confirm the effectiveness of the proposed BCN-based DIM and highlight its role in securing identity management processes within the O-RAN context. Finally, we address the use of efficient computational techniques in the context of PQC, which holds significant potential in terms of reducing energy consumption overall.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"8 3","pages":"895-909"},"PeriodicalIF":5.3,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142091077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Open RAN paves the way for standardized interfaces and enables the integration of network applications from diverse vendors, thereby enhancing network management flexibility. However, control decision conflicts occur when components from different vendors are deployed together. This article provides an overview of various types of conflicts that may occur in Open RAN, with a particular focus on intra-component conflict mitigation among Extended Applications (xApps) in the Near Real Time RAN Intelligent Controller (Near-RT-RIC). A QoS-Aware Conflict Mitigation (QACM) method is proposed that finds the optimal configuration of conflicting parameters while maximizing the number of xApps that have their Quality of Service (QoS) requirements met. We compare the performance of the proposed QACM method with two benchmark methods for priority and non-priority cases.

Privacy-preserving techniques aim to learn knowledge from sensitive data to improve services without compromising privacy. However, as the data scale increases, enforcing privacy-preserving techniques on sensitive data may consume a considerable amount of system resources and impose performance penalties. To reduce system resource consumption, we present NetDP, an in-network architecture for privacy-preserving techniques by leveraging programmable switches to improve resource efficiency (i.e., CPU cycles, network bandwidth, and privacy budgets). The key idea of NetDP is to accommodate and exploit cryptographic operators to reduce resource consumption rather than repetitively and exhaustively suppressing the impact of these techniques. To the best of our knowledge, this is the first time that privacy-preserving techniques in a large-scale data processing system have been enforced on programmable switches. Our experiments based on Tofino switches indicate that NetDP significantly reduces computation latency (e.g., 40.2%-55.8% latency in computations) without impacting fidelity.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"8 3","pages":"1076-1089"},"PeriodicalIF":5.3,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142090869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A widely adopted deployment scenario of 5G FWA includes edge cloud that supports computing services and Radio Access Network (RAN) functions. Such edge cloud requires network and energy resources for 5G FWA. This paper proposes renewable energy powered and Open RAN-based architecture for 5G FWA serving LDRAs using three-level closed-loops. Open RAN is a new 5G RAN architecture allowing Open Central Unit and Open Distributed Unit to be distributed in virtualized environment. The first closed-loop distributes radio resources to Open RAN instances and slices at the edge cloud. The second closed-loop allocates radio resources to houses. We design a new energy model that leverages renewable energy. We jointly optimize radio and energy resource allocation in closed-loop 3. We formulate ultra-small and small-time scale optimization problems that link closed-loops to maximize communication utility while minimizing energy costs. We propose reinforcement learning and successive convex approximation to solve the formulated problems. Then, we use solution data and continual learning to improve resource allocation on a large time scale.

To maximize the covert communication rate, which is characterized by the shared common rate and private rate of the covert user, the transmit beamforming, reflection/refraction beamforming, and common rate allocation need to be jointly optimized. By decoupling the original covert communication rate maximization problem into three sub-problems, an alternating optimization (AO) algorithm is designed to obtain the optimized solution to achieve the maximum covert communication rate. For the sub-problem of optimizing the common rate allocation, a closed-form expression is derived for the optimal common rate allocation. For the multiple-ratio fractional programming sub-problems of optimizing the transmit beamforming and reflection/refraction beamforming, Lagrangian dual formulation and quadratic transformation are utilized to reconstruct the objective function in the form difference of convex functions. Then, a penalized successive convex approximation is utilized to tackle the rank-one constrained beamforming optimization. Simulation results clarify the effectiveness of the proposed AO algorithm to achieve the maximum covert communication rate. Compared to the benchmark scheme in which the common rate allocation is missing, it is verified by simulation results that the STAR-RIS-aided MISO-RSMA scheme effectively increases the covert communication rate.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"8 4","pages":"1318-1331"},"PeriodicalIF":5.3,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
