Abstract

Named-Data Networking (NDN) over Low Power and Lossy Networks (LLNs), employing IEEE 802.15.4 communication technology, is projected to provide native support for mobility and efficient content delivery for the emerging Internet of Things (IoT). While many interest forwarding strategies have been proposed for NDNs over LLNs, most existing studies have relied on software simulations to evaluate their performance due to the lack of analytical modeling tools. This paper introduces the first analytical model for estimating the Interest Satisfaction Ratio (ISR) in NDN over LLNs, which is a crucial metric for assessing the effectiveness of interest forwarding strategies. We develop the analytical model specifically for the broadcast forwarding strategy, which has been extensively studied due to its simplicity and ease of implementation. Simulation results confirm that the proposed model predicts the ISR with reasonable accuracy. The model is then used to elucidate the strong interaction between the CSMA/CA parameters of the IEEE 802.15.4 standard and the achieved ISR.

关于估计基于 IEEE 802.15.4 命名数据网络中的兴趣满足率

采用 IEEE 802.15.4 通信技术的低功耗和有损网络（LLN）上的命名数据网络（NDN）预计将为新兴的物联网（IoT）提供移动性和高效内容交付的本地支持。虽然已经提出了许多通过 LLN 实现 NDN 的兴趣转发策略，但由于缺乏分析建模工具，大多数现有研究都依赖软件模拟来评估其性能。本文介绍了第一个用于估算 LLN 上 NDN 中兴趣满足率（ISR）的分析模型，这是评估兴趣转发策略有效性的一个重要指标。我们专门针对广播转发策略开发了该分析模型，广播转发策略因其简单和易于实施而被广泛研究。仿真结果证实，所提出的模型能合理准确地预测 ISR。然后，我们利用该模型阐明了 IEEE 802.15.4 标准的 CSMA/CA 参数与所实现的 ISR 之间的强烈相互作用。

期刊介绍： Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
