Despite its merits, it often leads to resource-intensive deployments, which raise energy concerns. These concerns are further amplified by the limited availability of resource orchestration strategies capable of addressing the multi-faceted nature of distributed AI. This work targets energy consumption minimization of distributed AI services by proposing a custom meta-heuristic, two-tier hierarchical genetic algorithm (HGA) that integrates a divide-and-conquer strategy to provide effective chained decision-making. The first tier of HGA determines the optimal placement of model partitions within an AI service on the underlying network, while the second tier focuses on strategic resource allocation for each partition, ensuring that service latency requirements are met. A safe strategy selection is proposed, applying a custom repair mechanism and a penalty function that discourages constraints violation. Evaluation results show the effectiveness and robustness of the proposed HGA, compared to two state-of-the-art baseline solutions, on different network environments and evaluation scenarios. HGA achieves up to 94.1% decrease in the total energy consumption per service compared to the baselines, while entirely eliminating infeasible strategies.</div></div>","PeriodicalId":55224,"journal":{"name":"Computer Communications","volume":"246 ","pages":"Article 108371"},"PeriodicalIF":4.3,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145618716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These networks comprise a control plane and a user plane. While the control plane is responsible for managing the network and its devices, the user plane forwards data and directly influences the experienced Quality of Service. A key network function in the user plane is the User Plane Function (UPF), which forwards packets between cellular network devices and the data network, such as the Internet or an edge data center. However, the extent to which existing UPF implementations can provide sufficient Quality of Service for emerging applications remains largely unexplored. In this work, we analyze and compare various UPF implementations from both theoretical and practical perspectives. We consider both software-based and hardware-accelerated implementations and compare them in terms of performance and latency under load.

Traditional approaches often fail to balance fault tolerance, communication latency, and task execution efficiency under such dynamic and adversarial conditions. This paper proposes the Consensus-based Information Sharing Framework (CISF), a novel solution specifically designed to ensure information consistency in dynamic disaster environments. CISF integrates a Stratified Parallel Byzantine Fault Tolerance (SPBFT) mechanism — optimized via a dynamic capability-reputation evaluation model — with a Multi-Round Search and Patrol Model (MSPM) based on an improved Cuckoo Search algorithm. MSPM employs a multi-objective fitness function to jointly optimize temporal efficiency, spatial coverage, and task priority, enabling comprehensive area exploration and continuous information validation. Theoretical analysis derives the optimal hierarchical ratio and the maximum fault tolerance threshold for CISF. Simulation results show that CISF maintains 93.8% consistency under Byzantine interference and reduces consensus latency by up to 56.2%, while remaining effective in highly dynamic environments. Overall, this study establishes a robust and efficient framework for achieving real-time, fault-tolerant information consistency in interference-prone UAV networks, offering broad applicability for future swarm-based disaster response systems.</div></div>","PeriodicalId":55224,"journal":{"name":"Computer Communications","volume":"247 ","pages":"Article 108408"},"PeriodicalIF":4.3,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145925932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the nonconvexity of the original problem and the interdependencies among multiple optimization variables, the problem is decomposed into three subproblems to optimize power and bandwidth allocation. To increase resource utilization and address user pairing challenges, a serial-optimized communication scheme is proposed, which leverages an optimized block coordinate descent (OP-BCD) method to sequentially solve the subproblems. Specifically, the power allocation strategy is optimized using an optimized deep Q-network (DQN) combined with a gradient ascent approach, whereas the intergroup bandwidth is optimized via a sequential least squares programming (SLSQP).

Unfortunately, single connectivity (SC) communications frequently fail to fulfill these stringent requirements. To address these challenges, employing a multi-connectivity (MC) solution appears to be a promising technique. In this paper, in the context of Horizon Europe COMMECT project, we seek to develop a multi-connectivity solution that intelligently integrates cellular and satellite networks for the purpose of monitoring livestock transport in rural regions where 5G coverage is limited. Multi-connectivity can be helpful for meeting EU regulations requiring seamless communication between transport units and the operational center to ensure animal welfare during transit. To achieve this, we employ machine learning (ML) models within a Classification and Regression framework in the proposed multi-connectivity solution. The ML models process radio-related key performance indicators (KPIs) as inputs to estimate network throughput and latency. The outputs of the model are used to decide whether to continue with the cellular link or activate the backup satellite link in the multi-connectivity setup, ensuring an almost uninterrupted connection. This capability is particularly crucial in regions where 5G coverage is limited, and maintaining a reliable connection is essential. To evaluate the proposed framework, we used a hybrid emulation setup based on experimental data collected in the northern part of Denmark. The emulation results demonstrate that the MC solution significantly outperforms the cellular SC. Although our solution is designed for livestock transport monitoring, it can be adapted for other applications, such as precision farming, in areas with insufficient 5G availability.</div></div>","PeriodicalId":55224,"journal":{"name":"Computer Communications","volume":"246 ","pages":"Article 108366"},"PeriodicalIF":4.3,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
