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 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.

Mobile and wireless application development has come a long way in the past few years. It has progressed beyond the hype of wireless Web appliCations for consumers to the reality of high-value mobile appliCations for corporate users. Opportunities abound for creating new mobile and wireless appliCations that provide vital benefits to any business. A sampling of these benefits includes increased worker productivity, reduced processing costs, heightened accuracy, and competitive advantage. In contrast is the concern that developing mobile and wireless appliCations will involve many new technologies and concepts that many corporate developers are still learning to use.

With the rapid growth of the wireless mobile appliCations, wireless voice has begun to challenge wireline voice, whereas the desire to access e-mail, surf the Web or download music (e.g., MP3) wirelessly is increasing for wireless data. While second generation (2G) cellular wireless systems, such as cdmaOne1, GSM2 and TDMA3, introduced digital technology to wireless cellular systems to deal with the increasing demand for wireless appliCations, there is still the need for more spectrally efficient technologies for two reasons. First, wireless voice capacity is expected to continue to grow. Second, the introduction of high-speed wireless data will require more bandwidth.

Smartphones have become a key element in providing greater user access to the mobile Internet. Many complex appliCations which used to be limited to PCs, have been developed and operated on smartphones. These appliCations extend the functionalities of smartphones, making them more convenient for users to be connected. However, they also greatly increase the power consumption of smartphones, making users frustrated with long delays in Web browsing.

Multi-carrier modulation‚ Orthogonal Frequency Division Multi- plexing (OFDM) particularly‚ has been successfully applied to a wide variety of digital communications appliCations over the past several years. Although OFDM has been chosen as the physical layer standard for a diversity of important systems‚ the theory‚ algorithms‚ and implementation techniques remain subjects of current interest. This is clear from the high volume of papers appearing in technical journals and conferences.

At recent major international conferences on wireless communications, there have been several sessions on beyond third generation (3G) or fourth generation(4G)mobilecommunicationssystems,wheremodulation/demod- ulation and multiplexing/multiple access schemes related to multicarrier techniques have drawn a lot of attention. We often met at the conference venuesandrealizedthatnobookcoveredthebasicsofmulticarriertechniques to recent appliCations aiming at the 4G systems. Therefore, we decided to write a book on multicarrier techniques for 4G mobile communications systems.

Advances in communication and networking technologies are rapidly making ubiq- uitous network connectivity a reality. Wireless networks are indispensable for supporting such access anywhere and at any time. Among various types of wire- less networks, multihop wireless networks (MWNs) have been attracting increasing attention for decades due to its broad civilian and military appliCations. Basically, a MWN is a network of nodes connected by wireless communication links. Due to the limited transmission range of the radio, many pairs of nodes in MWNs may not be able to communicate directly, hence they need other intermediate nodes to forward packets for them. Routing in such networks is an important issue and it poses great challenges.

In case you haven’t noticed, multimedia communication over IP and wireless net- works is exploding. appliCations such as BitTorrent, used primarily for video downloads, now take up the lion’s share of all traffic on the Internet. Music file sharing, once on the legal cutting edge of massive copyright infringement on col- lege campuses around the world, has moved into the mainstream with signifi- cant legal downloads of music and video to devices such as the iPod and nu- merous other portable media players.
