标题： MOHAF: A Multi-Objective Hierarchical Auction Framework for Scalable and Fair Resource Allocation in IoT Ecosystems

摘要： 物联网（IoT）生态系统迅速增长，加剧了在高度动态、分布式环境中高效分配异构资源的挑战。传统的集中式机制和单一目标拍卖模型，仅关注成本最小化或收益最大化等指标，难以实现平衡的系统性能。本文提出了多目标分层拍卖框架（MOHAF），这是一种分布式资源分配机制，可联合优化成本、服务质量（QoS）、能效和公平性。MOHAF结合了分层聚类以降低计算复杂度，并采用贪心、子模优化策略，保证（1-1/e）的近似比。一种动态定价机制能够实时适应资源利用率，提高市场稳定性和分配质量。在包含3,553个请求和888个资源的Google集群数据跟踪上进行的大量实验表明，MOHAF的分配效率（0.263）优于贪婪（0.185）、第一价格（0.138）和随机（0.101）拍卖，同时实现了完美的公平性（Jain指数=1.000）。消融研究表明，成本和QoS组件在维持平衡的多目标结果中起着关键作用。具有近线性可扩展性、理论保证和稳健的实证性能，MOHAF为大规模物联网部署提供了一个实用且适应性强的解决方案，有效协调分布式资源协调中的效率、公平性和可持续性。 显示英文摘要

摘要： The rapid growth of Internet of Things (IoT) ecosystems has intensified the challenge of efficiently allocating heterogeneous resources in highly dynamic, distributed environments. Conventional centralized mechanisms and single-objective auction models, focusing solely on metrics such as cost minimization or revenue maximization, struggle to deliver balanced system performance. This paper proposes the Multi-Objective Hierarchical Auction Framework (MOHAF), a distributed resource allocation mechanism that jointly optimizes cost, Quality of Service (QoS), energy efficiency, and fairness. MOHAF integrates hierarchical clustering to reduce computational complexity with a greedy, submodular optimization strategy that guarantees a (1-1/e) approximation ratio. A dynamic pricing mechanism adapts in real time to resource utilization, enhancing market stability and allocation quality. Extensive experiments on the Google Cluster Data trace, comprising 3,553 requests and 888 resources, demonstrate MOHAF's superior allocation efficiency (0.263) compared to Greedy (0.185), First-Price (0.138), and Random (0.101) auctions, while achieving perfect fairness (Jain's index = 1.000). Ablation studies reveal the critical influence of cost and QoS components in sustaining balanced multi-objective outcomes. With near-linear scalability, theoretical guarantees, and robust empirical performance, MOHAF offers a practical and adaptable solution for large-scale IoT deployments, effectively reconciling efficiency, equity, and sustainability in distributed resource coordination.
