The surge of mobile data traffic forces network
operators to cope with capacity shortage. The deployment of
small cells in 5G networks is meant to reduce latency, backhaul
traffic and increase radio access capacity. In this context, mobile
edge COMPuting technology will be used to manage dedicated
cache space in the radio access network. Thus, mobile network
operators will be able to provision OTT content providers with
new caching services to enhance the quality of experience of their
customers on the move.
Evolutionary Computation (EC) deals with problem solving, optimization, and
machine learning techniques inspired by principles of natural evolution and ge-
netics. Just from this basic definition, it is clear that one of the main features of
the research community involved in the study of its theory and in its applications
is multidisciplinarity. For this reason, EC has been able to draw the attention of
an ever-increasing number of researchers and practitioners in several fields.
The idea of writing this book entitled “Cognitive Networked Sensing and Big Data”
started with the plan to write a briefing book on wireless distributed COMPuting
and cognitive sensing. During our research on large-scale cognitive radio network
(and its experimental testbed), we realized that big data played a central role. As a
result, the book project reflects this paradigm shift. In the context, sensing roughly
is equivalent to “measurement.”
How will future generations refer to our times? Will it be known as one
of space exploration, genetics, atomic energy or COMPuting? Possibly,
but I think it is more likely to be ‘The age of communications’. Not since
printed books and newspapers were first introduced has there been
such an explosion of communication. None of this technology could
function without modern cables and, just as important, competent
installers.
Digital mobile wireless communication and the Internet have undergone a
fantastic growth in the last few years and, despite originating from two different
worlds, they are converging. This convergence corresponds to the evolution of
mobile systems towards the highest broadband data transmissions (GSM,
EDGE/GPRS, UMTS then HSDPA), while the COMPuting world gets equipped with
wireless technologies such as Wi-Fi or Wi-Max.
A wireless ad-hoc network is a wireless network deployed without any infrastructure. In
such a network, there is no access point or wireless router to forward messages among the
COMPuting devices. Instead, these devices depend on the ad-hoc mode of their wireless net‐
work interface cards to communicate with each other. If the nodes are within the transmis‐
sion range of the wireless signal, they can send messages to each other directly. Otherwise,
the nodes in between will forward the messages for them. Thus, each node is both an end
system and a router simultaneously.
Five years have passed since the first edition of this book was published.Over the five years,the
world has witnessed a technological revolution headlined by an array of exciting consumer and
industrial products such as the Nintendo Wii, Apple iPod/iPad, sensor-rich smart phones,
phones with cameras,new operating systems for mobile phones and apps,e-books,WiFi,voice-
over-IP calls, social networking, 3D animated movies, and cloud COMPuting, to name the major
ones that affect everyday living
The Raspberry Pi has become a COMPuting phenomenon. This single-board miniature
computer, first released in February 2012 by the Raspberry Pi Foundation, has grown into
a series of nearly a dozen models that have sold a total of more than 10 million units in
five years.
Inexpensive to buy and to run, Raspberry Pi computers are great for enthusiasts,
good for games, and fun for children. Raspberry Pi computers are also terrific in the
classroom, enabling you to put on each desk an easily-manageable computer on which
students can do everything from learning Internet use and essential office software skills,
through grasping programming basics in an easy-to-learn format, to performing full-on
programming in Python, Java, C, and other languages. Better yet, you can install all the
software needed for those activities automatically alongside the operating system.
With the proliferation of cloud COMPuting and Internet online services, more and
more data and computation are migrated to geographical distributed Internet data
centers (IDCs), which can provide reliability, management, and cost benefits.
However, IDC operators encounter several major problems in IDC operations, such
as huge energy consumption and energy cost, and high carbon emission. To deal
with the above problems, IDC operators have to efficiently manage the way of
energy consumption and energy supply. Considering the potential of smart grid, we
focus on the energy management of IDCs in smart grid from several perspectives,
i.e., power outage, carbon emission, heterogeneous service delay guarantees, and
operation risk.
Driven by the rapid advancement of technology and the growing need of business
requirements, cyber communications are embedded in many physical systems. The
integration of cyber and physical capabilities leads to the creation of many applica-
tions with enormous societal impact and economic benefit. The emerging systems
that connect the cyber-world of COMPuting and communications with the physical
world are cyber-physical systems (CPS).
