With smart sensing devices becoming a ubiquitous part of our connected world, the need to support large-scale communication involving Internet-of-Things (IoT) devices is becoming a reality. IoT traffic needs to be carried over cellular networks as it is the primary wide-area wireless communication infrastructure. However, the current 3GPP architecture and protocols are inefficient and difficult to scale, even if a small fraction of all IoT devices are mobile and have to be addressable/reachable through the Internet. In addition, link layer operations, traffic scheduling, and transport protocols currently in use are not well suited for typical short, periodic and bursty IoT communication patterns. This project aims to address these limitations by re-designing core operations and protocols involved in IoT data communication over cellular networks. The issues that the project will address are not only central to the efficient operation of current 3G/4G and future 5G networks, but must be solved to make the grand vision of the Internet-of-Things a reality. Through participation by industrial partners, the team will maximize the relevance and outreach of research to practice. The PIs will involve undergraduate students in their research, and integrate findings from this research into graduate courses, and encourage participation of under-represented students.Addressing the limitations of IoT data communication over cellular networks is challenging, as it requires supporting stringent requirements on limited capability (such as low power) end-systems, and maintaining only small amounts of state in the cellular network on a per-device basis. To address these challenges, the project will investigate novel mechanisms to eliminate cellular network tunnels by leveraging the locality of typical IoT mobility patterns and the capabilities of protocols that separate location-from-identity. Second, the project will investigate cross-layer mechanisms for adaptive optimization of Radio Resource Control (RRC) configurations towards attaining an ideal balance between end-device energy efficiency and information exchange overhead in the network. Third, the project will investigate new mechanisms for efficient traffic scheduling over the air-interface. Finally, the project plans to design a new transport that can dynamically adapt based on IoT application requirements, and is flexible enough to effectively handle the varying size of data transfers. The solutions will take into account the specific properties in IoT communication.

随着智能传感设备成为我们连接世界中无处不在的一部分，支持涉及涉及Thing Internet（IoT）设备的大规模沟通的需求已成为现实。物联网流量需要在蜂窝网络上携带，因为它是主要的广阔无线通信基础架构。 但是，即使所有物联网设备中的一小部分都是移动的，并且必须通过Internet可以解决/可以通过互联网，即使当前的3GPP体系结构和协议效率低下且难以扩展。此外，链接层操作，流量调度和当前正在使用的运输协议不太适合典型的简短，周期性和爆发的物联网通信模式。该项目旨在通过重新设计蜂窝网络上的物联网数据通信中涉及的核心操作和协议来解决这些限制。该项目将解决的问题不仅是当前3G/4G和未来5G网络的有效运行的核心，而且必须解决以使The Internet的宏伟愿景成为现实。通过工业合作伙伴的参与，团队将最大程度地提高与实践研究的相关性和宣传。 PI将使本科生参与他们的研究，并将这项研究的发现整合到研究生课程中，并鼓励参与不足的学生的参与。补充物联网数据通信对蜂窝网络的局限性是具有挑战性的，因为它需要对有限的能力（例如低功率）的责任基础，并在小组中维持众多的网络，并支持有限的能力（例如低功率）。为了应对这些挑战，该项目将通过利用典型的物联网迁移率模式的局部性以及分开位置与身份位置的协议的能力来调查消除细胞网络隧道的新型机制。其次，该项目将研究跨层机制，以自适应优化无线电资源控制（RRC）配置，以在网络中的最终设备能源效率和信息交换开销之间达到理想的平衡。第三，该项目将研究新机制，以在空气接口上进行有效的流量调度。最后，该项目计划设计一种可以根据IoT应用程序要求动态适应的新运输，并且足够灵活，可以有效地处理数据传输的不同大小。该解决方案将考虑物联网通信中的特定属性。
