ABSTRACT
The growing capabilities of sensing, computing and communication devices are leading to an explosion of Internet of Things (IoT) infrastructures. In the meantime, advances in technologies such as autonomous systems and artificial intelligence promise enormous economic and societal benefits. Naturally, it is desirable to deploy these technologies in IoT infrastructures. However, such deployments present daunting changes for increasingly scaled-up IoT infrastructures in mission-critical applications such as medical, energy, transportation, and industrial-automation systems. These challenges stem from several major aspects in terms of scalability. First, the number of edge devices can be enormous, often in the order of billions, which makes centralized management infeasible. Second, there are multiple layers of heterogeneity. An IoT system can consist of heterogeneous computing subsystems; each subsystem can have heterogeneous computing devices; and each single device can be composed of different kinds of computing components. Third, mission-critical applications have stringent requirements in correctness, resilience, timeliness, security and safety. It is difficult for a large-scale IoT system to satisfy these requirements due to increasing opportunities for adversarial activity.
To tackle these challenges, this project aims to develop a cross-layer and full hardware/software stack solution, referred to as the S3-IoT framework, for the design and deployment of scalable, secure, and smart mission-critical IoT systems. The S3-IoT framework will span three different computation layers, including data centers, gateways/aggregators, and edge devices, and cover four research foci, i.e., resource management, security and privacy, computer architecture/systems, and algorithms. In this planning project, an initial version of the S3-IoT framework will be developed. The S3-IoT framework will (i) leverage a layered structure - data centers, gateways/aggregators, and edge devices to accommodate the huge number of edge devices; (ii) develop cross-layer techniques to deal with the heterogeneity among these layers; and (iii) propose hardware and software co-design approaches that embrace the heterogeneity among computing components to improve the performance of all components within an individual layer. The S3-IoT framework will be evaluated by developing simulators with the layered structure as well as a small scale, comprehensive experimental testbed. The success of this planning project will lead to a convincing path to effective deployment of mission-critical IoT systems and infrastructures, particularly in terms of improving resilience to environmental uncertainties, system internal errors and faults, and malicious attacks.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

PROJECT OUTCOMES REPORT

This project has generated innovations for designing scalable, secure and smart IoT systems in the following aspects.
(1) Resource management: We have developed several network resource management techniques for Industrial IoT (IIoT) systems. These techniques successfully tackle several fundamental challenges in such systems, including (i) ensuring real-time Quality of Services (QoS), especially in the presence of unexpected external (i.e., application-side) and internal (i.e., network-side) disturbances, (ii) removing an unrealistic assumption used in many existing works, i.e., all wireless links are reliable, and (iii) supporting scalable deployment of the network resource management techniques.
(2) Security & privacy: We have developed novel attack detection and recovery methods to defend against sensor attacks in distributed devices in the field. These methods provide real-time and resilient defense through improving both the detection delay and accuracy, and safely recovering the devices to desired states before serious consequences occur.
(3) Computer architecture/systems: We have designed energy-efficient brain-inspired hyperdimensional computing architecture using voltage scaling. By leveraging the inherent error tolerance of hyperdimensional computing models, we are able to reduce the energy by 60%. We have also designed in-memory computing methods based on emerging memories to accelerate emerging applications.
We have developed simulators and extended experimental testbeds, and used them to evaluate and show the effectiveness of the proposed methods.
Through the support of this project, we have organized a workshop on Scalable Design of Resilient Mission-Critical IoT Systems. The workshop has allowed the PIs, other researchers and students to present their research results and initiate new collaborations.
