Wireless networking is undergoing a transformation from what has been primarily a medium for supporting voice traffic BETWEEN telephones, into what is increasingly becoming a medium for supporting traffic among a variety of digital devices transmitting media of many types (voice, data, images, video. etc.) Wireline networking underwent a similar transformation in the 1990s, which led to an enormous build-up in the capacity of such networks, primarily through the addition of new optical fiber, switches and other infrastructure.

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.

This book paves the path toward fourth generation (4G) mobile communica- tion by introducing mobility in heterogeneous IP networks with both third generation (3G) and wireless local area networks (WLANs), which is seen as one of the central issues in the becoming 4G of telecommunications networks and systems. This book presents a thorough overview of 3G networks and standards and discusses interworking and handover mechanisms BETWEEN WLANs and the Universal Mobile Telecommunication System (UMTS).

Static electricity is the most ancient form of electricity known to humans. More than 2000 years ago, the Greeks recognized the attraction BETWEEN certain mate- rials when they were rubbed together; indeed, the word electricity comes from the Greek elektron, which means amber. During the seventeenth and eighteenth centuries, several key experiments were conducted to understand and measure static electricity. But the discovery of electromagnetism and its formidable break- through has rapidly outgrown interest in static electricity. Even today, where the industrial applications of static electricity are not insignificant, they cannot compare with those of electromagnetism and electrodynamics.

The mature CMOS fabrication processes are available in many IC foundries. It is cost-effective to leverage the existing CMOS fabrication technologies to implement MEMS devices. On the other hand, the MEMS devices could also add values to the IC industry as the Moore’s law reaching its limit. The CMOS MEMS could play a key role to bridge the gap BETWEEN the CMOS and MEMS technologies. The CMOS MEMS also offers the advantage of monolithic integration of ICs and micro mechanical components.

The large-scale deployment of the smart grid (SG) paradigm could play a strategic role in supporting the evolution of conventional electrical grids toward active, flexible and self- healing web energy networks composed of distributed and cooperative energy resources. From a conceptual point of view, the SG is the convergence of information and operational technologies applied to the electric grid, providing sustainable options to customers and improved security. Advances in research on SGs could increase the efficiency of modern electrical power systems by: (i) supporting the massive penetration of small-scale distributed and dispersed generators; (ii) facilitating the integration of pervasive synchronized metering systems; (iii) improving the interaction and cooperation BETWEEN the network components; and (iv) allowing the wider deployment of self-healing and proactive control/protection paradigms.

This book is intended for researchers, teachers, and students willing to ex- plore conceptual bridges BETWEEN the fields of Automatic Control and Power Electronics. The need to bring the two disciplines closer has been felt, for many years, both by Power Electronics specialists and by Automatic Control theorists, as a means of fruitful interaction BETWEEN the two scientific com- munities. There have, certainly, been many steps given in that direction in the last decade as evidenced by the number of research articles in journals, special sessions in conferences, and summer courses throughout the world.

With the rapid development of electric vehicles (EVs) as well as the promotion and application of vehicle-to-grid (V2G) technologies, EVs charging loads, as flexible loads, have the potential to participate in the grid services, including peak shaving and valley filling, frequency regulation (FR), emergency power, energy market participation, and so on. Therefore, great attention has been paid to EVs and V2G. Focusing on the interactions BETWEEN EVs and power system, this book aims to bring readers with basic knowledge of electrical engineering promptly to the frontier of the EVs’ influence on power system and environment. This book may serve as a reference for scientists, electrical engineers, and postgraduate students majoring in electrical engineering or other related fields.

Switched systems are embedded devices widespread in industrial applications such as power electronics and automotive control. They consist of continuous-time dynamical subsystems and a rule that controls the switching BETWEEN them. Under a suitable control rule, the system can improve its steady-state performance and meet essential properties, such as safety and stability, in desirable operating zones.

Today, electric power transmission systems should face many demanding chal- lenges, which include balancing BETWEEN reliability, economics, environmental, and other social objectives to optimize the grid assets and satisfy the growing electrical demand. Moreover, the operational environment of transmission systems is becoming increasingly rigorous due to continually evolving functions of interconnected power networks from operation jurisdiction to control responsibly – coupled with the rising demand and expectation for reliability.
