Description: Intelligent reflecting surface (IRS) is a promising
technology to enhance the coverage and performance of wireless
networks. We consider the application of IRS to non-orthogonal
multiple access (NOMA), where a base station transmits superposed signals to multiple users by the virtue of an IRS. The
performance of an IRS-assisted NOMA networks with imperfect
successive interference cancellation (ipSIC) and perfect successive
interference cancellation (pSIC) is investigated by invoking 1-
bit coding scheme. In particular, we derive new exact and
asymptotic expressions for both outage probability and ergodic
rate of the m-th user with ipSIC/pSIC. Based on analytical
results, the diversity order of the m-th user with pSIC is in
connection with the number of reflecting elements and channel
ordering. The high signal-to-noise radio (SNR) slope of ergodic
rate for the m-th user is obtained. The throughput and energy
efficiency of IRS-NOMA networks are discussed both in delaylimited and delay-tolerant transmission modes. Additionally, we
derive new exact expressions of outage probability and ergodic
rate for IRS-assisted orthogonal multiple access (IRS-OMA).
Numerical results are presented to substantiate our analyses and
demonstrate that: i) The outage behaviors of IRS-NOMA are
superior to that of IRS-OMA and relaying schemes; ii) The M-th
user has a larger ergodic rate than IRS-OMA and benchmarks.
However, the ergodic performance of the m-th user exceeds
relaying schemes in the low SNR regime; and iii) The IRS-assisted
NOMA networks have ability to achieve the enhanced energy
efficiency compared to conventional cooperative communications Platform: |

Description: This book is now in its fifth edition. Each edition has corresponded to a dif
ferent phase in the way computer networks were used. When the first edition ap
peared in 1980, networks were an academic curiosity. When the second edition
appeared in 1988, networks were used by universities and large businesses. When
the third edition appeared in 1996, computer networks, especially the Internet, had
become a daily reality for millions of people. By the fourth edition, in 2003, wire
less networks and mobile computers had become commonplace for accessing the
Web and the Internet. Now, in the fifth edition, networks are about content dis
tribution (especially videos using CDNs and peer-to-peer networks) and mobile
phones are small computers on the Internet.
New in the Fifth Edition
Among the many changes in this book, the most important one is the addition
of Prof. David J. Wetherall as a co-author. David brings a rich background in net
working, having cut his teeth designing metropolitan-area networks more than 20
years ago. He has worked with the Internet and wireless networks ever since and
is a professor at the University of Washington, where he has been teaching and
doing research on computer networks and related topics for the past decade.
Of course, the book also has many changes to keep up with the: ever-changing
world of computer networks. Among these are revised and new material on
Wireless networks (802.12 and 802.16)
The 3G networks used by smart phones
RFID and sensor networks
Content distribution using CDNs
Peer-to-peer networks
Real-time media (from stored, streaming, and live sources)
Internet telephony (voice over IP)
