The significant applications of nanoparticles inspired the development of a mathematical model to analyze mass and heat transfer in magnetically influenced Williamson nanoliquid flow across an exponentially extendable surface by incorporating physical factors of Brownian motion and thermophoresis effects along with Arrhenius activation energy and convective boundary constraints. The fundamental equations describing the mathematical structure are designed in the sense of a highly nonlinear coupled partial differential setup.

Traditional handover algorithms in LTE systems prioritize metrics such as signal strength and load balancing, often overlooking the impact on energy consumption. This study addresses that gap by proposing an intelligent, data-driven handover optimization framework designed to reduce energy usage in heterogeneous LTE environments. The core objective is to enhance network sustainability without significantly compromising Quality of Service (QoS). To achieve this, we introduce a machine learning-based handover decision mechanism that integrates user behavior prediction and workload balancing. Thus, analyzing both user mobility patterns and network conditions, the proposed system identifies optimal timing and target cells for handovers. This proactive strategy minimizes unnecessary signaling and handover attempts, which are common sources of energy waste in traditional approaches. The framework includes a Mobility Load Balancing (MLB) algorithm that extends beyond conventional metrics, incorporating energy-awareness as a key factor in decision-making. Simulations demonstrate that our intelligent handover mechanism delivers substantial energy savings while maintaining service quality at acceptable levels. Specifically, it outperforms standard LTE handover methods by significantly reducing redundant handovers and base station power usage. This research not only contributes to the theoretical understanding of energy-efficient radio network (RN) management but also provides a practical solution for telecom operators aiming to deploy greener LTE infrastructures. Also, leveraging machine learning techniques, the proposed model supports more sustainable operations and helps networks better manage the increasing data demands of the Internet of Things (IoT) era. In summary, our work introduces a novel, intelligent approach to LTE handover management that aligns energy efficiency with service performance. The findings suggest that intelligent, predictive algorithms can play a pivotal role in creating more sustainable and cost-effective wireless networks.</div></div>","PeriodicalId":16920,"journal":{"name":"Journal of Radiation Research and Applied Sciences","volume":"18 3","pages":"Article 101599"},"PeriodicalIF":1.7,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
