Summary: In order to execute transactions on the Ethereum Mainnet and other blockchains, users need to pay fees in the form of cryptocurrency. While Ether can be purchased for the Ethereum blockchain, test networks and research blockchains distribute free Ether to users. Due to the consumption of blockchain resources, Ether is distributed in fixed small amounts. To address different user requirements and ensure fairness, a more general distribution mechanism based on Max-min Fairness is proposed. This research presents an algorithm and Solidity smart contract implementation that achieves low transaction costs independent of the number of users.

Summary: This paper investigates a multiuser multiple-input single-output wireless power transfer system assisted by reconfigurable intelligent surfaces, using a constant-envelope analog beamformer to jointly optimize ET beamforming and RIS phase shifts in order to maximize minimum received power. The non-convex max-min problem is iteratively solved using the successive convex approximation (SCA) method and alternating direction method of multipliers (ADMM) algorithm, demonstrating the effectiveness of the proposed algorithm and the performance gain brought by RISs.

Summary: LoRa has become a promising networking technology for IoT applications. However, the low data rate used by distant end devices to reach a LoRa gateway results in long transmission time and high energy consumption. This paper proposes EF-LoRa, a networking solution that achieves energy fairness among end devices by allocating network resources carefully. Extensive simulation results demonstrate that EF-LoRa improves energy fairness by 177.8% compared to existing solutions.

Summary: This study focuses on fairness-aware resource management in a multi-user and multi-server mobile edge computing network, aiming to minimize task execution latency while considering resource constraints. It proposes a low-complexity iteration based algorithm to find the global optimum of the problem by solving a convex feasibility problem in each iteration. Simulation results demonstrate that the proposed resource management strategy can reduce the maximum task execution latency of users by more than 15% compared to baseline approaches.

Summary: Fairness and efficiency are critical metrics for users in modern data center computing systems. To balance these two factors, we propose a new fairness-efficiency scheduler called QKnober, which uses a tunable fairness knob to achieve flexible balance. QKnober maximizes system efficiency and guarantees fairness properties such as sharing incentive.

Summary: The open-radio access network (O-RAN) utilizes cloudification and network function virtualization to process base-band functions through dis-aggregated radio units (RUs), distributed units (DUs), and centralized units (CUs). This paper proposes and compares the performances of min-max fairness and Vickrey-Clarke-Groves (VCG) auction-based x-haul and DU-CU resource allocation mechanisms, aiming to create a sustainable multi-tenant O-RAN ecosystem. The study considers TWDM PON-based x-haul interfaces and designs efficient heuristics for better economic efficiency and network resource utilization.
