This book emphasizes the increasingly important role that
Computational Intelligence (CI) methods are playing in solving a
myriad of entangled Wireless Sensor Networks (WSN) related
problems. The book serves as a guide for surveying several
state-of-the-art WSN scenarios in which CI approaches have been
employed. The reader finds in this book how CI has contributed to
solve a wide range of challenging problems, ranging from balancing
the cost and accuracy of heterogeneous sensor deployments to
recovering from real-time sensor failures to detecting attacks
launched by malicious sensor nodes and enacting CI-based security
schemes. Network managers, industry experts, academicians and
practitioners alike (mostly in computer engineering, computer
science or applied mathematics) benefit from th e spectrum of
successful applications reported in this book. Senior undergraduate
or graduate students may discover in this book some problems well
suited for their own research endeavors.
Optical networks epitomize complex communication systems, and they
comprise the Internet s infrastructural backbone. The first of its
kind, this book develops the mathematical framework needed from a
control perspective to tackle various game-theoretical problems in
optical networks. In doing so, it aims to help design control
algorithms that optimally allocate the resources of these networks.
With its fresh problem-solving approach, Game Theory in Optical
Networks is a unique resource for researchers, practitioners, and
graduate students in applied mathematics and systems/control
engineering, as well as those in electrical and computer
engineering."
This book provides a novel method for topic detection and
classification in social networks. The book addresses several
research and technical challenges that are currently being
investigated by the research community, from the analysis of
relations and communications between members of a community, to
quality, authority, relevance and timeliness of the content,
traffic prediction based on media consumption, spam detection, to
security, privacy and protection of personal information.
Furthermore, the book discusses innovative techniques to address
those challenges and provides novel solutions based on information
theory, sequence analysis and combinatorics, which are applied on
real data obtained from Twitter.
Due to the progress in VLSI technology, integrated circuit chips
are now available that allow video/image signal processing to be
performed with a single VLSI chip or small sets of VLSI chips.
Recent standardization on bandwidth compression schemes for still
images (JPEG) and motion pictures (H.261, R723, MPEG) also
encourage the development of VLSI video/image processors for
cost-effective solutions. Furthermore, recent trends suggest that
the standardization on HDTB bandwidth compression for broadcasting
and storage purposes is just around the corner. In terms of device
technology, however, the progress achieved in increasing speed is
not as high as that achieved by integration. The development of
high speed systems is due to architectural effort, rather than
device technology. This is why high speed architectures, such as
those for special wired logic realization and for multi-processors
are of great interest to VLSI system designers. VLSI Video/Image
Signal Processing is an edited volume of original research
comprising invited contributions by leading researchers.
The book presents a collection of peer-reviewed articles from the
11th KES International Conference on Intelligent Decision
Technologies (KES-IDT-19), held Malta on 17-19 June 2019. The
conference provided opportunities for the presentation of new
research results and discussion about them. It was also an
opportunity to generation of new ideas in the field of intelligent
decision making. The range of topics explored is wide, and covers
methods of classification, prediction, data analysis, decision
support, modelling and many more in such areas as finance,
cybersecurity, economy, health, management and transportation. The
topics cover also problems of data science, signal processing and
knowledge engineering.
Current research fields in science and technology were presented
and discussed at the EKC2008, informing about the interests and
directions of the scientists and engineers in EU countries and
Korea. The Conference has emerged from the idea of bringing
together EU and Korea to get to know each other better, especially
in fields of science and technology. The focus of the conference is
put on the topics: Computational Fluid Dynamics, Mechatronics and
Mechanical Engineering, Information and Communications Technology,
Life and Natural Sciences, Energy and Environmental Technology.
The existence of electrical noise is basically due to the fact that
electrical charge is not continuous but is carried in discrete
amounts equal to the electron charge. Electrical noise represents a
fundamental limit on the performance of electronic circuits and
systems. With the explosive growth in the personal mobile
communications market, the need for noise analysis/simulation
techniques for nonlinear electronic circuits and systems has been
re-emphasized. Even though most of the signal processing is done in
the digital domain, every wireless communication device has an
analog front-end which is usually the bottleneck in the design of
the whole system. The requirements for low-power operation and
higher levels of integration create new challenges in the design of
the analog signal processing subsystems of these mobile
communication devices. The effect of noise on the performance of
these inherently nonlinear analog circuits is becoming more and
more significant. Analysis and Simulation of Noise in Nonlinear
Electronic Circuits and Systems presents analysis, simulation and
characterization techniques and behavioral models for noise in
nonlinear electronic circuits and systems, along with practical
examples. This book treats the problem within the framework of, and
using techniques from, the probabilistic theory of stochastic
processes and stochastic differential systems. Analysis and
Simulation of Noise in Nonlinear Electronic Circuits and Systems
will be of interest to RF/analog designers as well as engineers
interested in stochastic modeling and simulation.
Asynchronous Transfer Mode (ATM) networks are widely considered to
be the new generation of high speed communication systems both for
broadband public information highways and for local and wide area
private networks. ATM is designed to integrate existing and future
voice, audio, image and data services. Moreover, ATM aims to
simplify the complexity of switching and buffer management, to
optimise intermediate node processing and buffering and to limit
transmission delays. However, to support such diverse services on
one integrated communication network, it is most essential, through
careful engineering, to achieve a fruitful balance amongst the
conflicting requirements of different quality of service
constraints ensuring that one service does not have adverse
implications on another. Over recent years there has been a great
deal of progress in research and development of ATM technology, but
there are still many interesting and important problems to be
resolved such as traffic characterisation and control, routing and
optimisation, ATM switching techniques and the provision of quality
of service. This book presents thirty-two research papers, both
from industry and academia, reflecting latest original achievements
in the theory and practice of performance modelling of ATM networks
worldwide. These papers were selected, subject to peer review, from
those submitted as extended and revised versions out of fifty-nine
shorter papers presented at the Second IFIP Workshop on
"Performance Modelling and Evaluation of ATM Networks" July 4-7,
1994, Bradford University. At least three referees from the
scientific committee and externally were involved in the selection
of each paper.
This book focuses on the design and testing of large-scale,
distributed signal processing systems, with a special emphasis on
systems architecture, tooling and best practices. Architecture
modeling, model checking, model-based evaluation and model-based
design optimization occupy central roles. Target systems with
resource constraints on processing, communication or energy supply
require non-trivial methodologies to model their non-functional
requirements, such as timeliness, robustness, lifetime and
"evolution" capacity. Besides the theoretical foundations of the
methodology, an engineering process and toolchain are described.
Real-world cases illustrate the theory and practice tested by the
authors in the course of the European project ARTEMIS DEMANES. The
book can be used as a "cookbook" for designers and practitioners
working with complex embedded systems like sensor networks for the
structural integrity monitoring of steel bridges, and distributed
micro-climate control systems for greenhouses and smart homes.
This book offers a comprehensive report on the technological
aspects of Mobile Health (mHealth) and discusses the main
challenges and future directions in the field. It is divided into
eight parts: (1) preventive and curative medicine; (2) remote
health monitoring; (3) interoperability; (4) framework,
architecture, and software/hardware systems; (5) cloud
applications; (6) radio technologies and applications; (7)
communication networks and systems; and (8) security and privacy
mechanisms. The first two parts cover sensor-based and bedside
systems for remotely monitoring patients' health condition, which
aim at preventing the development of health problems and managing
the prognosis of acute and chronic diseases. The related chapters
discuss how new sensing and wireless technologies can offer
accurate and cost-effective means for monitoring and evaluating
behavior of individuals with dementia and psychiatric disorders,
such as wandering behavior and sleep impairments. The following two
parts focus on architectures and higher level systems, and on the
challenges associated with their interoperability and scalability,
two important aspects that stand in the way of the widespread
deployment of mHealth systems. The remaining parts focus on
telecommunication support systems for mHealth, including radio
technologies, communication and cloud networks, and secure
health-related applications and systems. All in all, the book
offers a snapshot of the state-of-art in mHealth systems, and
addresses the needs of a multidisciplinary audience, including
engineers, computer scientists, healthcare providers, and medical
professionals, working in both academia and the industry, as well
as stakeholders at government agencies and non-profit
organizations.
Synthesis and Optimization of DSP Algorithms describes approaches
taken to synthesising structural hardware descriptions of digital
circuits from high-level descriptions of Digital Signal Processing
(DSP) algorithms. The book contains:
-A tutorial on the subjects of digital design and architectural
synthesis, intended for DSP engineers,
-A tutorial on the subject of DSP, intended for digital
designers,
-A discussion of techniques for estimating the peak values likely
to occur in a DSP system, thus enabling an appropriate signal
scaling. Analytic techniques, simulation techniques, and hybrids
are discussed. The applicability of different analytic approaches
to different types of DSP design is covered,
-The development of techniques to optimise the precision
requirements of a DSP algorithm, aiming for efficient
implementation in a custom parallel processor. The idea is to
trade-off numerical accuracy for area or power-consumption
advantages. Again, both analytic and simulation techniques for
estimating numerical accuracy are described and contrasted. Optimum
and heuristic approaches to precision optimisation are
discussed,
-A discussion of the importance of the scheduling, allocation, and
binding problems, and development of techniques to automate these
processes with reference to a precision-optimized algorithm,
-Future perspectives for synthesis and optimization of DSP
algorithms. A wide body of literature exists covering separately
the areas of DSP, hardware design, and design automation. This book
brings together the fields, concentrating on those transformations,
optimizations, and design techniques that would usually be
considered to cross the domain boundaries between "pure DSP" and
"pure digital implementation." As such, this book forms a valuable
contribution to the existing literature.
Synthesis and Optimization of DSP Algorithms is of use both to
researchers and students in the field of design automation for DSP
systems, and to those wishing to implement state-of-the-art
techniques within an Electronic Design Automation framework.
This book is an introduction to the mathematical description of information in science and engineering. The necessary ma- thematical theory will be treated in a more vivid way than in the usual theoretical proof structure. This enables the reader to develop an idea of the connections between diffe- rent information measures and to understand the trains of thoughts in their derivation. As there exist a great number of different possible ways to describe information, these measures are presented in a coherent manner. Some examples of the information measures examined are: Shannon informati- on, applied in coding theory; Akaike information criterion, used in system identification to determine auto-regressive models and in neural networks to identify the number of neu- rons; and Cramer-Rao bound or Fisher information, describing the minimal variances achieved by unbiased estimators.
This book is an outcome of the second national conference on
Communication, Cloud and Big Data (CCB) held during November 10-11,
2016 at Sikkim Manipal Institute of Technology. The nineteen
chapters of the book are some of the accepted papers of CCB 2016.
These chapters have undergone review process and then subsequent
series of improvements. The book contains chapters on various
aspects of communication, computation, cloud and big data. Routing
in wireless sensor networks, modulation techniques, spectrum hole
sensing in cognitive radio networks, antenna design, network
security, Quality of Service issues in routing, medium access
control protocol for Internet of Things, and TCP performance over
different routing protocols used in mobile ad-hoc networks are some
of the topics discussed in different chapters of this book which
fall under the domain of communication. Moreover, there are
chapters in this book discussing topics like applications of
geographic information systems, use of radar for road safety, image
segmentation and digital media processing, web content management
system, human computer interaction, and natural language processing
in the context of Bodo language. These chapters may fall under
broader domain of computation. Issues like robot navigation
exploring cloud technology, and application of big data analytics
in higher education are also discussed in two different chapters.
These chapters fall under the domains of cloud and big data,
respectively.
A Primer of Signal Detection Theory is being reprinted to fill the
gap in literature on Signal Detection Theory--a theory that is
still important in psychology, hearing, vision, audiology, and
related subjects. This book is intended to present the methods of
Signal Detection Theory to a person with a basic mathematical
background. It assumes knowledge only of elementary algebra and
elementary statistics. Symbols and terminology are kept at a basic
level so that the eventual and hoped for transfer to a more
advanced text will be accomplished as easily as possible. Intended
for undergraduate students at an introductory level, the book is
divided into two sections. The first part introduces the basic
ideas of detection theory and its fundamental measures. Its aim is
to enable the reader to be able to understand and compute these
measures. It concludes with a detailed analysis of a typical
experiment and a discussion of some of the problems which can arise
for the potential user of detection theory. The second section
considers three more advanced topics: threshold theory, the
extension of detection theory, and an examination of Thurstonian
scaling procedures.
In this volume the investigations of filtering problems, a start on
which has been made in 55], are being continued and are devoted to
theoretical problems of processing stochastic fields. The
derivation of the theory of processing stochastic fields is similar
to that of the theory extensively developed for stochastic
processes ('stochastic fields with a one-dimensional domain').
Nevertheless there exist essential distinctions between these cases
making a construction of the theory for the multi-dimensional case
in such a way difficult. Among these are the absence of the notion
of the 'past-future' in the case of fields, which plays a
fundamental role in constructing stochastic processes theory. So
attempts to introduce naturally the notion of the causality
(non-anticipativity) when synthesising stable filters designed for
processing fields have not met with success. Mathematically,
principal distinctions between multi-dimensional and
one-dimensional cases imply that the set of roots of a
multi-variable polyno mial does not necessary consist of a finite
number of isolated points. From the main theorem of algebra it
follows that in the one-dimensional case every poly nomial of
degree n has just n roots (considering their multiplicity) in the
com plex plane. As a consequence, in particular, an arbitrary
rational function cents(."
This book concerns two major topics, smart antenna systems and
wireless local-area-networks (LANs). For smart antenna systems, it
d- cusses the mechanics behind a smart antenna system, the setup of
a smart antenna experimental testbed, and experimental and computer
simulation results of various issues relating to smart antenna
systems. For wireless LAN systems, it discusses the IEEE 802.11
worldwide wi- less LAN standard, the operation of a wireless LAN
system, and some of the technical considerations that must be
overcome by a wireless LAN system designer. These two topics are
combined in the discussion of the Smart Wireless LAN (SWL) system,
which was designed to achieve the benefits which smart antenna
systems can provide for wireless LAN systems while still remaining
compatible with the 802.11 wireless LAN standard. The design of SWL
calls for the replacement of the conv- tional wireless LAN base
station (which are called access points in the 802.11
documentation) with an SWL base station, while leaving the -
dividual terminal operation as unchanged as possible.
Nonlinear optical phenomena can be exploited in advanced devices
for transport, processing, and storage of information. These are
needed as the present-day approach - mainly using on electron-based
technology - faces the challenges of increasing demand on bandwidth
and processing speed. A key role in the development of nonlinear
devices is the availability of novel materials with the required
nonlinear optical properties. With such materials, scientific
creativity and careful design, promising concepts have been
developed resulting in the demonstration of devices. This book
contains the proceedings of NOIS 2000 (Nonlinear Optics for the
Information Society) Annual Meeting of the COST Action P2, held at
the University of Twente, in Enschede, The Netherlands, on 26-27
October, 2000. It comprises a selection of the presentations at the
meeting, reporting state-of-the-art research and developments in
the field of applications of nonlinear phenomena in information
technology.

This book is a collection of invited papers that were presented at
the Ninth IEEE International Symposium on Personal, Indoor and
Mobile Radio Communications, September 5-8, 1998, Boston, MA. These
papers are meant to provide a global view of the emerging
third-generation wireless networks in the wake of the third
millennium. Following the tradition of the PIMRC conferences, the
papers are selected to strike a balance between the diverse
interests of academia and industry by addressing issues of interest
to the designers, manufacturers, and service providers involved in
the wireless networking industry. The tradition of publishing a
collection of the invited papers presented at the PIMRC started in
PIMRC'97, Helsinki, Finland. There are two benefits to this
tradition (1) it provides a shorter version of the proceedings of
the conference that is more focused on a specific theme (2) the
papers are comprehensive and are subject of a more careful review
process to improve the contents as well as the presentation of the
material, making it more appealing for archival as a reference
book. The production costs of the book is subsidized by the
conference and the editors have donated the royalty income of the
book to the conference.
ATM Network Performance describes a unified approach to ATM network
management. The focus is on satisfying quality-of-service
requirements for individual B-ISDN connections. For an ATM network
of output-buffer switches, the author describes how the basic
network resources (switch buffer memory and link transmission
bandwidth) should be allocated to achieve the required
quality-of-service connections. The performance of proposed
bandwidth scheduling policies is evaluated. Both single node and
end-to-end performance results are given. In particular, these
results are applied to resource provisioning problems for
prerecorded (stored) video and video teleconferencing. The flow
control problem for available bit rate traffic is also described.
This book is intended for a one-term course in performance of
Broadband Integrated-Services Digital Networks (B-ISDNs) based on a
type of packet-switched communication network called Asynchronous
Transfer Mode (ATM). The level of presentation is at the first year
of graduate studies and for professionals working in the field, but
it may be accessible to senior undergraduates as well. Some
familiarity with ATM standards is assumed as such standards are
only briefly outlined. All of the required background in
discrete-time queueing theory is supplied. Exercises are given at
the end of chapters. Solutions and/or hints to selected exercises
are given in an Appendix.
This thesis presents a significant contribution to decentralized
resource allocation problems with strategic agents. The study
focused on three classes of problems arising in communication
networks. (C1). Unicast service provisioning in wired networks.
(C2). Multi-rate multicast service provisioning in wired networks.
(C3). Power allocation and spectrum sharing in multi-user
multi-channel wireless communication systems. Problems in (C1) are
market problems; problems in (C2) are a combination of markets and
public goods; problems in (C3) are public goods. Dr. Kakhbod
developed game forms/mechanisms for unicast and multi-rate
multicast service provisioning that possess specific properties.
First, the allocations corresponding to all Nash equilibria (NE) of
the games induced by the mechanisms are optimal solutions of the
corresponding centralized allocation problems, where the objective
is the maximization of the sum of the agents' utilities. Second,
the strategic agents voluntarily participate in the allocation
process. Third, the budget is balanced at the allocations
corresponding to all NE of the game induced by the mechanism as
well as at all other feasible allocations. For the power allocation
and spectrum sharing problem, he developed a game form that
possesses the second and third properties as detailed above along
with a fourth property: the allocations corresponding to all NE of
the game induced by the mechanism are Pareto optimal. The thesis
contributes to the state of the art of mechanism design theory. In
particular, designing efficient mechanisms for the class of
problems that are a combination of markets and public goods, for
the first time, have been addressed in this thesis. The exposition,
although highly rigorous and technical, is elegant and insightful
which makes this thesis work easily accessible to those just
entering this field and will also be much appreciated by experts in
the field.
