Internet-of-Things (IoT) can provide ubiquitous connectivity for things and devices in the physical world and the related information in the digital world. IoT applications are anticipated to reduce costs, improve productivity, and provide new revenue sources. IoT spending will maintain a double-digit annual growth rate throughout the forecast period till 2022 and the global spending will surpass US$1 trillion in 2022 [IDC forecast in 2019]. Wireless technologies are a key enabler in the IoT era. To support future massive IoT applications scattering in large areas, there exist several critical challenges in addressing the high-reliability, low-latency, and wide-coverage requirements. Traditional layered Internet architecture and wireless solutions have difficulty dealing with the stringent delay and reliability requirements of IoT applications. Considering the new features and requirements of IoT data traffic, we propose to develop a novel network architecture built on the concept of wireless pipeline. Wireless signals can propagate along a multi-hop wireless pipeline, where synchronized transmissions are scheduled so the information can be forwarded within the pipeline close to the propagation speed. Such a virtual-circuit switching type architecture can ensure low-latency, high-reliability transmissions over long distances. Different from classic virtual-circuit switching networks where the resources of each wired communication links are orthogonal to each other, for wireless pipelines, mutual interferences within the pipeline and among different pipelines are unavoidable. Given the wireless impairments and mutual interference, we will develop advanced signal processing technologies, effective protocols, and optimized control mechanisms to ensure low latency, high reliability, and high efficiency, based on the software-defined networking and network function virtualization platform. Another challenge for IoT systems is mobility and dynamic topology. We will investigate fast and robust pipeline establishment and maintenance protocols for effective topology control and mobility management. Finally, IoT technologies for cyber-physical systems should be agile to deal with the system control objectives, so the IoT control strategies and the wireless pipeline communication protocols will be jointly designed and optimized. The proposed wireless pipeline architecture and protocols will form the basis for future academic-industry collaborations in IoT research, and for developing software-defined radio and software-defined networking-based test platform for validation, performance evaluation, and technology transfer.

Things Internet（IoT）可以为物理世界中的事物和设备以及数字世界中的相关信息提供无处不在的连接性。预计物联网应用程序将降低成本，提高生产率并提供新的收入来源。物联网支出将在整个预测期间保持两位数的年增长率，直到2022年，全球支出将超过2022年的1万亿美元[IDC预测2019年]。无线技术支持未来大规模的物联网应用在大面积的散射，在满足高可靠性，低延迟和广泛覆盖要求方面存在一些关键挑战。传统的分层互联网架构和无线解决方案很难处理物联网应用程序的严格延迟和可靠性要求。考虑到物联网数据流量的新功能和要求，我们建议开发一种基于无线管道概念的新型网络体系结构。无线信号可以沿多跳线无线管道传播，该管道安排了同步传输，以便可以在接近传播速度的管道中转发信息。这样的虚拟电路开关类型架构可以确保长距离长距离的低延迟，高可靠性传输。与经典的虚拟电路交换网络不同，每个有线通信链接的资源彼此之间是正交的，对于无线协议，需求中的相互作用和不同配方之间的相互作用是不可避免的。鉴于无线障碍和相互干扰，我们将根据软件定义的网络和网络功能虚拟化平台，开发高级信号处理技术，有效的协议和优化的控制机制，以确保低延迟，高可靠性和高效率。物联网系统的另一个挑战是移动性和动态拓扑。我们将研究快速，强大的管道建立和维护协议，以进行有效的拓扑控制和移动性管理。最后，针对网络物理系统的物联网技术应敏捷地处理系统控制目标，因此IoT控制策略和无线管道通信协议将共同设计和优化。拟议的无线管道体系结构和协议将构成IoT研究中未来学术行业协作的基础，并开发软件定义的无线电和软件定义的基于网络的测试平台，以验证，性能评估和技术传输。
