Summary: This paper investigates the resource allocation problem in a NOMA-based Wireless Energy Harvesting Sensor Network (WEHSN) to improve energy efficiency and system throughput. By converting the problem to a parametric form and applying the KKT conditions, a closed-form expression for optimization is derived. Numerical results show that the NOMA-based WEHSN outperforms the OFDMA and TDMA-based methods in terms of energy efficiency and throughput.

Summary: This article investigates the deployment of federated learning in an energy harvesting wireless network. A joint energy management and user scheduling method is proposed to minimize the training loss of federated learning. The original optimization problem is simplified and solved based on the analysis of federated learning convergence rate. Simulation results show that the proposed algorithm can reduce the training loss.

Summary: This paper proposes an energy-efficient resource allocation algorithm (EERAA) to prolong the lifetime of a WSN-based smart irrigation system under realistic scenarios. In the proposed algorithm, power allocation and subcarrier assignment are performed consecutively, considering the impact of intercarrier interference (ICI) caused by timing offset. The obtained results reveal that the proposed algorithm can reduce the network energy consumption by up to 30% while maintaining a high level of system performance in terms of secondary users' (SUs) averaged capacity.

Summary: Energy harvesting provides an attractive and promising mechanism for powering low-energy devices. However, it alone cannot achieve energy-neutral operation. To address this challenge, we propose a framework that optimizes energy allocation using a sequential algorithm, achieving higher utility under energy-limited scenarios.

Summary: To enhance network performance and improve energy efficiency in energy harvesting wireless sensor networks (EH-WSNs), a novel energy efficiency model and relay deployment scheme are proposed in this letter. The minimum relay maximum energy efficiency (MRMEE) problem, which is NP-hard, is formulated and solved using a particle swarm optimization-genetic algorithm (PSO-GA). Simulation results demonstrate that the proposed approach can improve energy efficiency and prolong network lifetime compared with other methods.

Summary: In traditional federated learning (FL), edge devices jointly train a machine learning model by communicating learning updates without exchanging data samples. In this study, a two-tier FL network is considered, where IoT nodes are the core clients, low altitude aerial platforms (UAVs) serve as model aggregators at the middle tier, and a high-altitude aerial platform (UAV with relatively high altitude) acts as the top-most layer aggregator. The energy-efficient computation and communication resource allocation in this network is addressed using an iterative algorithm that solves separate subproblems and then jointly solves the entire problem. Offline and online client scheduling schemes are proposed for optimal edge node selection and workload assignment based on data quality and workload constraints. Extensive simulations with real data verify the effectiveness of the proposed resource allocation scheme and highlight the importance of considering both computation, communication, and model divergence weight in FL performance.
