To address this, on-demand charging from an external power source is fundamental for the effective operation of energy-critical WRSNs. In this article, the wireless charging of the independent WRSNs in a network is modeled as a service in a common competitive market, where multiple charging service providers (CSPs) indulge in a pricing war to maximize their profits by achieving fair market share based on area division. A competitive market scenario is considered where multiple non-cooperative CSPs are strategically located at their fixed grounded stations, and the most economical CSP gets requested from a WRSN for charging. The CSPs are associated with UAV-enabled chargers (UAVEC), which are dispatched to the concerned WRSNs with known positions and recharged wirelessly in a time-bound manner. This paper study a suitable pricing strategy for on-demand charging of the WRSNs in a competitive market scenario; and investigate the existence of Nash equilibrium (NE) for prices and profits of CSPs using a game-theoretic approach. The closed-form expressions of NE conditions and the CSP selection criterion for WRSNs are obtained, and the results are verified through simulations.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"9 2","pages":"459-470"},"PeriodicalIF":5.3,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117181","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}

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}

To address this issue, incorporating phase errors, spatial correlation, and imperfect CSI into a unified outage-constrained beamforming optimization framework can be extended from i.i.d. Rician model to correlated Rician model. Subsequently, the outage constrained power minimizing problem is first transformed into a convex problem through Bernstein-type inequality method. Then, precoder and reflection beamforming are iteratively optimized under the alternate optimization (AO) framework. Especially, the scheme adopts semidefinite relaxation (SDR) technology and element iteration method to optimize the passive beamforming and achieve better performance than Gaussian randomization scheme. The simulation results demonstrate the effectiveness of the proposed scheme in two models. Compared to i.i.d. model, which is more sensitive to CSI errors, correlated model can provide more robust QoS guarantees for large CSI uncertainty sets. Phase errors undermine transmission power under the two models, especially in the i.i.d. model. Further, deploying more RIS elements can effectively improve the transmission power. Ultimately, the proposed approach has the potential to improve transmission robustness in practical scenarios.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"9 2","pages":"658-669"},"PeriodicalIF":5.3,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117183","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}

To address this issue, we propose an energy-latency tradeoff scheme for the joint optimization of vehicle selection and resource allocation in UAV-assisted VEC. Our investigation focuses on maximizing long-term training rewards for vehicle selection and resource allocation in FL, while considering constraints such as UAV energy consumption, vehicular energy consumption, bandwidth, and vehicle mobility. This problem is formulated as a Mixed-Integer Nonlinear Programming (MINLP) problem and modeled as a Markov Decision Process (MDP). We proposed an algorithm based on AdamW and Butterfly Optimization Algorithm (BOA) for Double-Depth Q-networks (AB-DDQN) to determine the optimal decisions. To expedite algorithm convergence, we replace the stochastic gradient descent (SGD) algorithm with AdamW algorithm and employ BOA to select hyperparameters, enhancing algorithm performance.

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}

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.
