IoT connects a large number of physical objects with the Internet that capture and exchange real-time information for service provisioning. Traditional network management schemes face challenges to manage vast amounts of network traffic generated by IoT services. Software-defined networking (SDN) and information-centric networking (ICN) are two complementary technologies that could be integrated to solve the challenges of different aspects of IoT service provisioning. ICN offers a clean-slate design to accommodate continuously increasing network traffic by considering content as a network primitive. It provides a novel solution for information propagation and delivery for large-scale IoT services. On the other hand, SDN allocates overall network management responsibilities to a central controller, where network elements act merely as traffic forwarding components. An SDN-enabled network supports ICN without deploying ICN-capable hardware. Therefore, the integration of SDN and ICN provides benefits for large-scale IoT services. This article provides a comprehensive survey on software-defined information-centric Internet of Things (SDIC-IoT) for IoT service provisioning. We present critical enabling technologies of SDIC-IoT, discuss its architecture, and describe its benefits for IoT service provisioning. We elaborate on key IoT service provisioning requirements and discuss how SDIC-IoT supports different aspects of IoT services. We define different taxonomies of SDIC-IoT literature based on various performance parameters. Furthermore, we extensively discuss different use cases, synergies, and advances to realize the SDIC-IoT concept. Finally, we present current challenges and future research directions of IoT service provisioning using SDIC-IoT.

使用软件定义的信息中心网络补充物联网服务：综合调查


物联网将大量物理对象与互联网连接起来，捕获和交换实时信息以提供服务。传统的网络管理方案面临着管理物联网服务产生的大量网络流量的挑战。软件定义网络（SDN）和信息中心网络（ICN）是两种互补的技术，可以集成起来解决物联网服务提供不同方面的挑战。 ICN 提供了一种全新的设计，通过将内容视为网络原语来适应不断增加的网络流量。它为大规模物联网服务的信息传播和交付提供了一种新颖的解决方案。另一方面，SDN将整体网络管理职责分配给中央控制器，其中网络元件仅充当流量转发组件。支持 SDN 的网络无需部署支持 ICN 的硬件即可支持 ICN。因此，SDN和ICN的集成为大规模物联网服务提供了好处。本文对用于物联网服务提供的软件定义的以信息为中心的物联网 (SDIC-IoT) 进行了全面的调查。我们介绍国投物联网的关键支持技术，讨论其架构，并描述其对物联网服务提供的优势。我们详细阐述了关键的物联网服务提供要求，并讨论了国投物联网如何支持物联网服务的不同方面。我们根据各种性能参数定义了国投物联网文献的不同分类法。此外，我们还广泛讨论了实现 SDIC-IoT 概念的不同用例、协同效应和进步。最后，我们提出了使用 SDIC-IoT 提供物联网服务的当前挑战和未来研究方向。
