Going beyond classic networking principles and architectures for
better wireless performance
Written by authors with vast experience in academia and
industry, Wireless Mesh Networks provides its readers with a
thorough overview and in-depth understanding of the
state-of-the-art in wireless mesh networking. It offers guidance on
how to develop new ideas to advance this technology, and how to
support emerging applications and services. The contents of the
book follow the TCP/IP protocol stack, starting from the physical
layer. Functionalities and existing protocols and algorithms for
each protocol layer are covered in depth. The book is written in an
accessible textbook style, and contains supporting materials such
as problems and exercises to assist learning.
Key Features:
* Presents an in-depth explanation of recent advances and open
research issues in wireless mesh networking, and offers concrete
and comprehensive material to guide deployment and product
development
* Describes system architectures and applications of wireless
mesh networks (WMNs), and discusses the critical factors
influencing protocol design
* Explores theoretical network capacity and the state-of-the-art
protocols related to WMNs
* Surveys standards that have been specified and standard drafts
that are being specified for WMNs, in particular the latest
standardization results in IEEE 802.11s, 802.15.5, 802.16 mesh
mode, and 802.16 relay mode
* Includes an accompanying website with PPT-slides, further
reading, tutorial material, exercises, and solutions
Advanced students on networking, computer science, and
electrical engineering courses will find Wireless Mesh
Networks an essential read. It will also be of interest to
wireless networking academics, researchers, and engineers at
universities and in industry.
