Wireless Sensor Networks have a wide range of applications in
different areas. Their main constraint is the limited and
irreplaceable power source of the sensor nodes. In many
applications, energy conservation of the sensor nodes and their
replacement or replenishment due to the hostile nature of the
environment is the most challenging issue. Energy efficient
clustering and routing are the two main important topics studied
extensively for this purpose. This book focuses on the energy
efficient clustering and routing with a great emphasis on the
evolutionary approaches. It provides a comprehensive and systematic
introduction of the fundamentals of WSNs, major issues and
effective solutions.
This book is very useful for the scholars who are interested in the
field of parallel computing at large and specifically in
Opto-electronic Interconnection system (OTIS). OTIS has attracted
many scientists and researches because of hybrid structure and
hierarchical properties and extensive literature is also available.
In this book, we have presented various parallel algorithms for
problems including Lagrange interpolation, Durand-Kerner root
finding, sorting, all-to-all communication, single-source shortest
path routing and conflict graph construction on different OTIS
models. In mapping these algorithms, intensive data movements are
required over the intra-group links (electronic) as well as
inter-group links (optical). Therefore, to analyze the time
complexity of the proposed algorithms, we count the data movements
through the electronic links as electronic moves and through the
optical links as OTIS moves. We have also compared our work with
the existing algorithms proposed by other scholars. This book will
definitely motivate the scholars to explore all possible ways, an
algorithm can be mapped on an OTIS model to improve the overall
time complexity.
Recent innovation in the field of Very Large Scale Integration has
resulted into fabrication of high speed processors. The sequential
computers, equipped with such high speed processors, are unable to
meet the challenges of various real-life and real- time
computational problems in the areas of image processing, climate
modeling, remote sensing, medical science etc., that require to
process massive volume of data. Parallel processing is one of the
most appropriate technologies that can meet the challenges of such
application areas. A variety of numeric and non-numeric problems
are often required to be solved in the above mentioned areas.
Prefix computation, polynomial root finding, matrix-matrix
multiplication, conflict graph construction are some of the very
important computations, which are frequently used for solving such
problems. In this thesis, we mainly focus on the design of parallel
algorithms for such computations to map them efficiently on
suitable interconnection networks. We also study a specific
interconnection network, called OTIS-Mesh of trees. We establish
its various topological properties and propose several parallel
algorithms on it.
This book includes a collection of peer-reviewed best selected
research papers presented at the Third International Conference on
Advances in Distributed Computing and Machine Learning (ICADCML
2022), organized by Department of Computer Science and Engineering,
National Institute of Technology, Warangal, Telangana, India,
during 15-16 January 2022. This book presents recent innovations in
the field of scalable distributed systems in addition to cutting
edge research in the field of Internet of Things (IoT) and
blockchain in distributed environments.
