Motivation, Opportunities and
Challenges of IoT
of Things” (IoT) refers to the digitization
of the world—the process of embedding microelectronic devices with integrated
sensing, computing, actuation and communication functions in almost any object
on the planet.
provides an unprecedented opportunity for any enterprise to access enormous
amounts of data over the internet for their business/operations optimization.
present two-layer internet—with edge nodes and the cloud—will be overwhelmed by
the massive amounts of data expected to be generated by IoT.
to enable IoT will require a replacing the present two-layer network with a
multi-layered network consisting of edge devices, and a heterogeneous network
of compute nodes, reaching the cloud.
solution, known as Fog Computing,
will enable every segment of industry, including automotive, manufacturing,
healthcare, food processing and agriculture, communication, transportation,
education, defense, and many more, to be engaged in the development and/or the
utilization of IoT. IoT also gives rise to numerous new opportunities and
challenges in technology,
and its impact on society.
massive amounts of data generated by the billions of nodes provides an
unprecedented opportunity for achieving greater economies of scale by
optimizing systems using machine learning and data-analytics. The use of such data-driven
methods raises a multitude of new legal,
also presents difficult technology challenges due to the fact that IoT involves
distributed, real-time computations, that occur over a large and dynamically
changing environment (e.g. processor load, link bandwidth, storage capacity,
fault events, cyber security, power consumption and energy capacity etc.).
and business challenges will arise from the joint
creation of software and hardware components by
multiple entities, and the sharing
and use of
the massive amounts data. These raise
issues of liability, data ownership, IP ownership, ensuring equitable benefits
of the technology, regulatory mechanisms to ensure privacy, security, and
safety, and standardization to enable interoperability and transparency, and
many other unforeseen consequences of IoT.
Additional business challenges include ways to monetize IoT when HW/SW
components and data are created by numerous enterprises.
Vision of NESTT
that IoT will be massively disruptive technology, potentially affecting all
segments of society, the vision
of the proposed effort is to contribute to the creation of an equitable, safe
and secure connected world to improve the quality of life for humanity.
Multiple scientific, engineering
realize the vision, we plan to establish a multi-disciplinary research center
named NESTT—Networked, Embedded, Smart
and Trusted Things.
is to create holistic
IoT solutions from the start (see Fig.
by combining expertise from multiple technology disciplines with expertise in
law, business, medicine and humanities.
address the diversity of the challenges, NESTT will be a multi-university
center, with Arizona State University (ASU), Southern Illinois University
Carbondale (SIUC), the University of Southern California (USC) and the
University of Arizona (UA) being the foundational members.
addition to involving faculty from the traditional disciplines of science and
engineering (electrical, computer), NESTT will also include faculty from the
schools of business, law and humanities to address the many societal and
business challenges that IoT presents.
will be founded on the principles and practices of the National Science
Foundation (NSF) Industry/University Cooperative Research Center model.
Development: The new workforce has to be technically nimble, and have the
skills to rapidly acquire new skills. Technical skills of NESTT students will
be supplemented with strong social skills and skills to collaborate with a wide
range of disciplines outside the traditional science and engineering domains.
