Fordecades,microwavelineofsight(LOS)linkshavebeenoneofthebasictechnolo- gies used to build telephone NetWorks. Until 1980, the fast rollout of high capacity transport NetWorks and deployment of links in areas with challenging geographic characteristics could not be understood without this technology.

Due to the asymmetry between the amount of data traffic in the downlink and uplink direction of nowadays and future wireless NetWorks, a proper design of the transceivers in the broadcast channel is inevitable in order to satisfy the users’ demands on data rate and transmission quality. This book deals with the optimi- zation-based joint design of the transmit and receive filters in a MIMO broadcast channel in which the user terminals may be equipped with several antenna ele- ments.

There is a phenomenal burst of research activities in mobile cloud computing systems, which extends cloud computing functions, ser- vices, and results to the world of future mobile communications applications, and the paradigm of cloud computing and virtualization to mobile NetWorks. Mobile applications demand greater resources and improved interactivity for better user experience.

Mobile multimedia communication is increasingly in demand because of the basic need to communi- cate at any time, anywhere, using any technology. In addition, to voice communication, people have a desire to access a range of other services that comprise multimedia elements—text, image, animation, high fidelity audio and video using mobile communication NetWorks. To meet these demands, mobile communication technologies has evolved from analog to digital, and the NetWorks have passed through a number of generations from first generation (1G) to fourth generation (4G).

Mobile radio NetWorks have risen in prominence over the last few years, primarily by the rise in popularity of cellular phones. It is important to recognise however that mobile radio technology fulfils a far wider range of applications that meet the demands of the modern world. These include the NetWorks that allow police and emergency services to serve the public, military NetWorks for operations and humanitarian support, and the mobile technol- ogies that are vital to the safety of aircraft.

Wireless metropolitan area NetWorks (WirelessMANs) is emerging as a promising broadband wireless access (BWA) technology to provide high-speed, high bandwidth efficiency and high-capacity multimedia services for residential as well as enterprise applications. It is observed that WirelessMAN (e.g., WiMAX) is even regarded as a 4G technology. For the success of the WirelessMANs, international standardization organiza- tions are very actively specifying the standards IEEE 802.16, ETSI HiperMAN and Korea WiBro.

The last decade proved to be hugely successful for the mobile communications industry, characterised by continued and rapid growth in demand, spurred on by new technological advances and innovative marketing techniques. Of course, when we refer to mobile commu- nications, we tend to implicitly refer to cellular systems, such as GSM. The plight of the mobile-satellite industry over the last decade, although eventful, has, at times, been more akin to an out of control roller coaster ride.

In general there are three different techniques for performance evaluation of systems and NetWorks: mathematical analysis, measurements, and computer simulation. All these techniques have their strength and weaknesses. In the literature there are plenty of discussions about when to use which technique, how to apply it, and which pitfalls are related to which evaluation technique.

This paper covers the keynote address delivered by the Chairman of the COST Action 285 at the Symposium. It outlines the studies undertaken by the members of the Action with the objective of enhancing existing modeling and simulation tools and to develop new ones for research in emerging multiservice telecommunication NetWorks. The paper shows how the scope of COST Action 285 has been enriched by the contributions made at the Symposium.
