Издательство Springer, 2007, -476 pp. Today’s wireless services have come a long way since the roll out of the conventional voice-centric cellular systems. The demand for wireless access in voice and high rate data multi-media applications has been increasing. New generation wireless communication systems are aimed at accommodating this demand through better resource management and improved transmission technologies. The interest in increasing S...

A volume in the IEEE Communications Society series: The ComSoc Guides to Communications Technologies. IEEE Press - John Wiley & Sons, Inc., 2011, - 217 pages. This book provides an overview of the current state-of-the-art in modeling and simulation (M&S) tools and discusses many of the pitfalls most commonly encountered by network engineers. A bottom-up approach is taken in describing network M&S, following the Transport Control Prot...

John Wiley & Sons Ltd, 2009. – 362 pages. Wireless communications and networks have experienced booming growth in the past few decades, with billions of new wireless devices in use each year. In the next decade we expect the exponential growth of wireless devices to result in a challenging shortage of spectrum suitable for wireless communications. Departing from the traditional approach to increase the spectral ef?ciency of physical layer tra...

IEEE Signal Processing Magazine, Vol. 25 No 6, November 2008, pp. 12-23. In recent years, the development of intelligent, adaptive wireless devices called cognitive radios, together with the introduction of secondary spectrum licensing, has led to a new paradigm in communications: cognitive networks. Cognitive networks are wireless networks that consist of several types of users: often a primary user (the primary license-holder of a spectrum band...

Издательство Springer, 2007, -458 pp. Cognitive radio has emerged as a promising technology for maximizing the utilization of the limited radio bandwidth while accommodating the increasing amount of services and applications in wireless networks. A cognitive radio (CR) transceiver is able to adapt to the dynamic radio environment and the network parameters to maximize the utilization of the limited radio resources while providing flexibility in...

619 pages. Cambridge University Press 2011. With the rapid growth of new wireless devices and applications over the past decade, the demand for wireless radio spectrum is increasing relentlessly. The development of cognitive radio networking provides a framework for making the best possible use of limited spectrum resources, and it is revolutionising the telecommunications industry. This book presents the fundamentals of designing, implementing,...

John Wiley & Sons, Inc., 2006. – 488 pages. This book is about making radios so smart that they can autonomously discover how, when, and where to use radio spectrum to obtain information services without having previously been programmed to do so. Cognitive radio integrates machine perception software into wireless systems—radio nodes and networks. Radios today are evolving from awareness (e.g., of location) toward cognition: the self-aware r...
