The series Internet Of Things - Technologies, Communications and Computing
publishes new developments and advances in the various areas of the different
facets of the Internet of Things.
The intent is to cover technology (smart devices, wireless sensors, systems),
communications (networksandprotocols) andcomputing(theory,middleware and
applications) of the Internet of Things, as embedded in the fields of engineering,
computer science, life sciences, as well as the methodologies behind them. The
series contains monographs, lecture notes and edited volumes in the Internet of
Things research and development area, spanning the areas of wireless sensor
networks, autonomic networking, network protocol, agent-based computing,
artificial intelligence, selforganizing systems, multi-sensor data fusion, smart
objects, and hybrid intelligent systems.

Preface
Communication environments of the future will be fundamentally different than
those in use today. One basic assumption underlies all of the reasoning of this
book—software is acquiring a definitive role in almost every sector of virtually
everyindustry,includingcommunications.Inparticular,theintegrationofnewICT
capabilities will determine and shape the evolution of communication systems
toward a new smart environment supporting and enriching the human need to
“communicate”.Thisintegrationwillundoubtedlyshakethetraditionalfoundations
of the telecoms industry.
The main focus of the book is to determine whether the communications
industry is undergoing a structural transformation or a consolidation of the current
technologies, systems, and business models based on connectivity. Its basic state-
mentisthatthereisatechnologicalparadigmshiftunderwaycalledsoftwarization.
The possibility that the ICT ecosystem is moving toward the adoption of new
technologiesthatcouldenablenewscenariosandapplicationdomainsbackedupby
networking (e.g., smart environments) is thoroughly analyzed.
This book distinguishes itself by its use of a user-centric approach, i.e., an
analysis of the technological evolution as driven by the need to satisfy the
requirementsofpeople(customersandusers).Adoptingtheuser’sviewpointoffers
atotally different perspectiveofthetechnological evolution andcanstimulatenew
and more compelling choices intheserviceandnetwork frameworks. Specifically,
the book shows how different technologies can be integrated with a user-centric
approach and how that process offers the possibility of creating a new kind of
network enabling new, appealing scenarios.
Covering a range of pertinent subjects, this book presents an analysis of the
major technological trends that have (and that will have) an impact on the
telecommunications ecosystem, such as software-defined networking, virtualiza-
tion, and cloud computing. These technologies can be combined in different ways

to support “traditional” or more advanced technological infrastructures. Specific
business considerations related to technological choices are put forward, followed
by a set of possible scenarios characterized by the prevalence of specific tech-
nologies and their related business models.

a bit of credit. Here we have to thank those people who shared their insights and
suggestions: Antonio Manzalini and Corrado Moiso. Discussions with them were
fruitful and rich with new hints and inspiration for further research.
During that same period, an enlightened CEO and his Strategy Vice President
found our outlook interesting and listened to our story. One result of that meeting
can be summarized in a single sentence: there is a need for a book about new
services and new networks. We wish to thank them even if we must keep them
anonymous. But we can publicly thank Roberto Saracco, at the time in Telecom
Italia,forsupportingtheworkandgivingusthefreedomtosayhowthingsstandin
this ever-changing telecommunications world. We are honored to have his preface
to our book.
Thisprocessmadeitcleartousthattheworkweweredoingonmy(Roberto’s)
doctoral thesis could have a general value beyond the normal scientific audience,
and so we decided to make it into a book. In the meantime, the scientific sugges-
tions and criticisms (because we needed to have qualified people play the role of
devil’s advocate) of Prof. Tiziana Margaria, Prof. Djamal Zeghlache, and subse-
quently Prof. Stéphane Frenot and especially Prof. Yvon Kermarrec were funda-
mental for strengthening the approach and the results. On a more business and
deployment perspective, Max Michel’s input made the material more consistent,
includingfrom theperspectiveofindustry. Wegladlythank themall for theirhelp
