However, in such a multi-device coexistence environment, efficiently allocating limited time-frequency resources to mitigate communication interference and enhance system performance has become a critical challenge. To address these issues, this article proposes a comprehensive solution that integrates master selection, resource allocation, and task scheduling to optimize resource utilization and service quality in smart home IoT systems. For device management, we propose a hierarchical entropy weight method (HEWM), considering factors such as device parameters, sensing capabilities, communication performance, and device interoperability. This method ensures efficient and stable selection of the primary device, optimizing network topology and communication efficiency. For resource allocation, we introduce a proximal policy optimization (PPO) algorithm that dynamically adjusts time-frequency resource allocation based on the varying device usage, network load, and communication condition. This adaptive strategy reduces interference between devices and improves system throughput. For task scheduling, we develop a task urgency-based queueing (TUQ) mechanism that prioritizes tasks based on urgency. A task preemption mechanism ensures that high-urgency tasks are processed with minimal delay, enhancing scheduling efficiency and service responsiveness. Simulation results show that the proposed approach significantly outperforms traditional methods in smart home IoT scenarios, achieving higher primary device scores, a 3%\u201322% improvement in system throughput, and a 5%\u201336% reduction in task delay.<\/jats:p>","DOI":"10.1145\/3717839","type":"journal-article","created":{"date-parts":[[2025,2,17]],"date-time":"2025-02-17T11:26:21Z","timestamp":1739791581000},"page":"1-24","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Service-Oriented Resource Allocation and Task Scheduling for Wi-Fi and Bluetooth Coexistence in Smart Home IoT Systems"],"prefix":"10.1145","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0511-2381","authenticated-orcid":false,"given":"Di","family":"Zhao","sequence":"first","affiliation":[{"name":"Xidian University State Key Laboratory of Integrated Services Network, Xi'an, China and Xidian University Hangzhou Institute of Technology, Hangzhou, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9234-2714","authenticated-orcid":false,"given":"Tianxu","family":"Niu","sequence":"additional","affiliation":[{"name":"Xidian University State Key Laboratory of Integrated Services Network, Xi'an, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8096-3370","authenticated-orcid":false,"given":"Bin","family":"Song","sequence":"additional","affiliation":[{"name":"Xidian University State Key Laboratory of Integrated Services Network, Xi'an, China and Xidian University Hangzhou Institute of Technology, Hangzhou, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4235-9671","authenticated-orcid":false,"given":"Xiaojiang","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Stevens Institute of Technology, Hoboken, United States"}]}],"member":"320","published-online":{"date-parts":[[2025,3,13]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-016-3335-4"},{"key":"e_1_3_1_3_2","first-page":"1","volume-title":"IEEE Emerging Technologies Symposium on Broadband, Wireless Internet Access","author":"Camp Michael T.","year":"2000","unstructured":"Michael T.
