The explosive increase of network-enabled sensors, actuators, and other cyber-physical systems, referred to as the Internet of Things (IoT), together with the proliferation of proprietary network infrastructures that largely bypass the public Internet, requires new solutions for interconnecting large numbers of heterogeneous networks. This project seeks to develop an internetworking architecture that is based on self-organizing application-layer networks. Self-organizing means that devices use all their communication modalities to detect and establish connectivity with other devices to form a network. All nodes of an application-layer network participate in relaying data between sources and destinations of information. Application-layer internetworking refers to the interconnection of devices with attachment points in different network infrastructures at the level of application programs. The long-term objective of this project is to explore the foundations of application-layer internetworking and develop new protocol solutions that enable and facilitate such internetworking. The project will address challenges of integrating low-power IoT devices into the novel internetworking architecture, and addresses scalable routing, resilience to failures, and network policies. The proposed research program seeks to make contributions to a future of highly interconnected networks of IoT and legacy devices. A separate thrust, but an integral part of the project, is the development of new traffic control algorithms using the framework of network calculus theory. Novel trends in technology, such as the ultra-reliable low-latency communication (URLLC) service in 5G networks, have increased the demand for novel scheduling and shaping algorithms. We seek to design algorithms that are based on the sound mathematical principles of the network calculus and that allow an efficient implementation in deployed systems. Doing so we seek to develop theoretical underpinnings for  scheduling and shaping algorithms in modern communication networks. By providing implementations of the developed scheduling and shaping methods, the project seeks to close the gap between the outcome of academic research and deployable technologies. Research activities of this project involve theoretical and experimental research, including the design of algorithms, protocol design and implementation, as well as analytical performance evaluation, simulations, and measurement experiments.

支持网络的传感器、执行器和其他网络物理系统（称为物联网（IoT））的爆炸性增长，以及在很大程度上绕过公共互联网的专有网络基础设施的激增，需要用于互连大量异构网络的新解决方案。本项目旨在开发一种基于自组织应用层网络的互联网络架构。自组织意味着设备使用其所有通信模式来检测并建立与其他设备的连接以形成网络。应用层网络的所有节点都参与在信息源和目的地之间中继数据。应用层互联是指设备与不同网络基础设施中的连接点在应用程序级别上的互连。这个项目的长期目标是探索应用层互联的基础，并开发新的协议解决方案，使这种互联和促进。该项目将解决将低功耗物联网设备集成到新型互联网络架构中的挑战，并解决可扩展路由、故障恢复能力和网络策略等问题。拟议的研究计划旨在为物联网和传统设备高度互连网络的未来做出贡献。 一个单独的推力，但该项目的一个组成部分，是新的交通控制算法的开发使用网络微积分理论的框架。技术的新趋势，例如5G网络中的超可靠低延迟通信（URLLC）服务，增加了对新型调度和整形算法的需求。我们寻求设计的算法，是基于健全的数学原理的网络演算，并允许在部署的系统中有效的实施。这样做，我们寻求在现代通信网络中的调度和整形算法的理论基础。通过提供开发的调度和成形方法的实现，该项目旨在缩小学术研究成果与可部署技术之间的差距。该项目的研究活动涉及理论和实验研究，包括算法设计，协议设计和实现，以及分析性能评估，模拟和测量实验。
