Wireless Mesh Networks (WMN) are believed to be a highly promising
technology and will play an increasingly important role in future
generation wireless mobile networks. WMN is characterized by
dynamic self-organization, self-configuration and self-healing to
enable quick deployment, easy maintenance, low cost, high scalability
and reliable services, as well as enhancing network capacity, connect-
ivity and resilience.

This chapter provides extensive coverage of existing mobile wireless technologies. Much of the
emphasis is on the highly anticipated 3G cellular networks and widely deployed wireless local
area networks (LANs), as the next-generation smart phones are likely to offer at least these two
types of connectivity. Other wireless technologies that either have already been commercialized or
are undergoing active research and standardization are introduced as well. Because standardization
plays a crucial role in developing a new technology and a market, throughout the discussion
standards organizations and industry forums or consortiums of some technologies are introduced.
In addition, the last section of this chapter presents a list of standards in the wireless arena.

Welcome to the third volume of the book entitled Technologies for the Wireless Future, which
is produced by WWRF. The idea is to take the most important outputs from the working
groups and special-interest groups that compose the Forum and bring them together in a series
of one-volume surveys. The latest of these will give the reader a good overview of the WWRF
approach to analyzing the future of wireless and mobile communications, as well as an insight
into the trends themselves and the key technologies that will be deployed.

HIS IS THE THIRD —and most likely the last—book
in the series on information technology for
energy managers and web based energy infor-
mation and control systems. This book concentrates on
web based enterprise energy and building automation
systems, and serves as a capstone volume in this series.
The thrust here is that the highest level functions of a
building and facility automation system are provided
by a web based EIS/ECS system that provides energy
management, maintenance management, overall facility
operational management, and ties in with the enterprise
resource management system for the entire facility or
the group of facilities being managed. If there were ever
to be a fourth volume in this series, it would follow
the logical progression of the first three volumes, and
would probably be titled Web Based Enterprise Resource
Management Systems.

Electricity has been chosen as the most convenient and useful form of energy, due
to its ease of transportation over large distances and easy conversion to other
energy forms. The biggest inconvenience with electricity is that it cannot be stored
and must be utilized at the moment of generation. The storage of a large amount of
electrical energy is usually connected with its conversion to other types of energy,
which significantly reduces the efficiency of such processes. The aim of the power
system, often treated as the biggest and the most complex machine ever built, is to
deliver uninterruptible electric energy of demanded quality parameters to
consumers.

This book is written for engineers involved in the operation, control, and
planning of electric power systems. In addition, the book provides information and
tools for researchers working in the fields of power system security and stability. The
book consists of two volumes. The first volume provides traditional techniques for the
stability analysis of large scale power systems. In addition, an overview of the main
drivers and requirements for modernization of the traditional methods for online
applications are discussed. The second volume provides techniques for online security
assessment and corrective action studies. In addition, the impact of variable generation
on the security of power systems is considered in the second volume. The first volume
may be considered as a background builder while the second volume is intended for
the coverage of edge techniques and methods for online dynamic security studies.

A revolution in power industries, including generation, transmission and distribution, driven by
environmental and economic considerations, is taking place all over the world. The smart grid allows for
integration of diverse generation and storage options, reduced losses, improved efficiencies, increased
grid flexibility, reduced power outages, allowing for competitive electricity pricing and integration of
electric vehicles and overall becoming more responsive to market, consumer and societal needs. It is
bringing profound changes to both power systems and many related industries.

The use of renewable energy systems, such as wind power, hydropower, tidal
power, solar power, geothermal power and biomass burn is growing. Research in
electric power generation from renewable sources is continuously expanding and
stands for an area of high technological and financial importance. The implemen-
tation of new technologies for the functioning and management of renewable
energy systems will help to further develop the renewable energy sector.

Commercial energy storage has moved from the margins to the mainstream as it
fosters flexibility in our smarter, increasingly integrated energy systems. The
energy density, availability, and relatively clean fossil profile of natural gas ensure
its critical role as a fuel for heating and electricity generation. As a transportation
fuel, natural gas continues to increase its market penetration; much of this has been
enabled by emerging developments in storage technology.
