Abstract

The rapid growth of the Internet of Things (IoT) has driven the demand for efficient indoor monitoring systems that can provide reliable connectivity, low latency, and high energy efficiency. Traditional wireless approaches based solely on radio frequency (RF) suffer from spectrum congestion and interference, while visible light communication (VLC) systems are constrained by line-of-sight requirements and limited coverage. To address these challenges, this paper proposes a hybrid VLC/RF network architecture integrated with distributed deep learning for IoT-based indoor monitoring. In the proposed framework, IoT devices leverage VLC links for high-speed data transmission in favorable conditions and seamlessly switch to RF links to maintain connectivity in non-line-of-sight scenarios. A distributed deep learning framework is deployed across edge nodes to enable scalable and privacy-preserving analytics, reducing reliance on centralized processing while improving adaptability to dynamic indoor environments. Experimental evaluation demonstrates that the proposed system achieves higher monitoring accuracy, reduced latency, and improved energy efficiency compared to single-mode VLC or RF systems. These findings highlight the potential of hybrid communication networks combined with distributed intelligence to enhance the performance and robustness of IoT indoor monitoring applications in smart homes, healthcare, and industrial environments.
在混合VLC/RF网络架构中,通过分布式深度学习实现高效物联网室内监控
物联网(IoT)的快速增长推动了对高效室内监控系统的需求,这些系统可以提供可靠的连接、低延迟和高能效。传统的仅基于射频(RF)的无线方法受到频谱拥塞和干扰的困扰,而可见光通信(VLC)系统则受到视距要求和有限覆盖范围的限制。为了解决这些挑战,本文提出了一种结合分布式深度学习的混合VLC/RF网络架构,用于基于物联网的室内监测。在提议的框架中,物联网设备利用VLC链路在有利条件下进行高速数据传输,并无缝切换到RF链路,以保持非视距场景下的连接。跨边缘节点部署分布式深度学习框架,以实现可扩展和隐私保护分析,减少对集中处理的依赖,同时提高对动态室内环境的适应性。实验评估表明,与单模VLC或RF系统相比,该系统具有更高的监测精度、更低的延迟和更高的能量效率。这些发现突出了混合通信网络与分布式智能相结合的潜力,可以提高智能家居、医疗保健和工业环境中物联网室内监控应用的性能和稳健性。
