Book Description

This book is a comprehensive guide to understanding the design of wireless multimedia communications systems. Covering mobile video, voice, and data communications, it provides both professionals and students with an introduction to the problems and solutions of communicating multimedia traffic at high data rates over a radio channel for short distances. Wireless Multimedia Communications begins with an examination of the physical layer of the Open Systems Interface (OSI) stack, modeling the radio channel impairments, including path loss and multipath distortion. The book addresses infrared and satellite wireless channels and the digital modulation approaches used to convey information over these channels. It compares possible approaches to transmitting multimedia traffic, including equalization, multicarrier modulation, and spread spectrum. The book also presents an in-depth discussion of error control, with a look at the emerging and promising field of turbo coding. At the data link layer, the book presents an evaluation of Medium Access Control (MAC) protocols-such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Code Division Multiple Access (

Book Description

Multimedia communications poses a number of challenges to the wireless networks. Traditional multiple access mechanisms in wireless local area networks (WLANs) are not suitable for conveying voice and video traffic. Various interferences, like intra-flow and inter-flow interference, detrimentally affects video streaming quality. Recently standardized multiple-input multiple-output (MIMO) technology in WLAN, IEEE 802.11n, although increases the data rate, its rate adaptation schemes cannot effectively support video streaming rates. On the other hand, the lossy nature of wireless networks results in inaccuracies in quality evaluation of video streaming. Such inaccuracies create hurdles for future development of multimedia communications in wireless networks. We propose to consider the characteristics of the multimedia application and that of wireless communications together, and take the advantages of these properties to develop communication protocols which can support multimedia delivery effectively. We propose a new multiple access protocol, Time Division Carrier-Sensing Multiple Access (TD-CSMA). Using the predictability of real-time traffic, TD-CSMA doubles the capacity of co-located multiple WLANs compared with the legacy CSMA. We also propose a new rate adaptation scheme, Video-aware Rate Adaptation (VARA). Based on the streaming rate variation of videos, VARA achieves the perfect quality for the high-definition (HD) video streaming in MIMO WLANs. Finally, by taking the impact of packet loss in wireless networks on video quality into account, we propose new video quality metrics. The new metrics can accurately evaluate the spatial and temporal quality of video streaming in wireless networks. From extensive experiments and subjective tests, our metrics show an correlation greater than 0.9 with the Mean Opinion Score (MOS) of human subjects. With the proposals in this thesis, we can greatly improve the performance of multimedia communications over wireless networks.

Book Description

During 12-15 of September 1999, 10th International Symposium on P- sonal, Indoor and Mobile Radio Communications (PIMRC’99) was held in Osaka Japan, and it was really a successful symposium that accommodated more than 600 participants from more than 30 countries and regions. PIMRC is really well organized annual symposium for wireless multimedia commu- cation systems, in which, various up-to-date topics are discussed in the invited talk, panel discussions and tutorial sessions. One of the unique features of the PIMRC is that PIMRC is continuing to publish, from Kluwer Academic Publishers since 1997, a book that collects the hottest topics discussed in PIMRC. In PIMRC’97, Invited talks were sum- rized in “Wireless Communications –TDMA versus CDMA – (ISBN 0-7923- 8005-3),” and it was published just beforePIMRC’97. This book was also distributed to all the PIMRC’97 participants as a part of proceedings for the conference. In PIMRC’98, extendedversion of the invited papers were s- marized in Wireless Multimedia Network Technologies (ISBN 0-7923-8633- 7) and published in September 1999, which is almost the same timing for the PIMRC’99. In the case of PIMRC’99, to produce more informative book, we have - lected topics that attracted many PIMRC’99 participants during the conf- ence, and invited prospective authors not only from the invited speakers but also from tutorial speakers, panel organizers, panelists, and some other exc- lent PIMRC’99 participants.

Book Description

In bringing to the readers the book 5G Multimedia Communication: Technology, Multiservices and Deployment, the aim is to present current work and direction on the challenging subject of multimedia communications, with theoretical and practical roots. The past two decades have witnessed an extremely fast evolution of mobile cellular network technology. The fifth generation of mobile wireless systems has achieved the first milestone toward finalization and deployment by 2020. This is vital to the development of future multimedia communications. Also, it is necessary to consider 5G technology from the performance point of view by analyzing network capabilities to the operator and to the end user in terms of data rate, capacity, coverage, energy efficiency, connectivity and latency. The book is divided into three major parts with each part containing four to seven chapters: • Critical enabling technology • Multiservices network • Deployment scenarios The first part discusses enabling technologies, such as green communication, channel modeling, massive and distributed MIMO and ML-based networks. In the second part, different methodologies and standards for multiservices have been discussed. Exclusive chapters have been dedicated to each of the open research challenges such as multimedia operating in 5G environment, network slicing optimization, mobile edge computing, mobile video multicast/broadcast, integrated satellite and drone communication. The third part paved the way to deployment scenarios for different innovative services including integration of a multienergy system in smart cities, intelligent transportation systems, 5G connectivity in the transport sector, healthcare services, 5G edge-based video surveillance and challenges of connectivity for massive IoT in 5G and beyond systems. The book is written by experts in the field who introduced scientific and engineering concepts, covering the 5G multimedia communication areas. The book can be read cover-to-cover or selectively in the areas of interest for the readers. Generally, the book is intended for novel readers who could benefit from understanding general concepts, practitioners who seek guidance into the field and senior-level as well as graduate-level engineering students in understanding the process of today’s wireless multimedia communications.
