This book reviews the concept of Software-Defined Networking (SDN)
by studying the SDN architecture. It provides a detailed analysis
of state-of-the-art distributed SDN controller platforms by
assessing their advantages and drawbacks and classifying them in
novel ways according to various criteria. Additionally, a thorough
examination of the major challenges of existing distributed SDN
controllers is provided along with insights into emerging and
future trends in that area. Decentralization challenges in
large-scale networks are tackled using three novel approaches,
applied to the SDN control plane presented in the book. The first
approach addresses the SDN controller placement optimization
problem in large-scale IoT-like networks by proposing novel
scalability and reliability aware controller placement strategies.
The second and third approaches tackle the knowledge sharing
problem between the distributed controllers by suggesting adaptive
multilevel consistency models following the concept of continuous
Quorum-based consistency. These approaches have been validated
using different SDN applications, developed from real-world SDN
controllers.
This book introduces the reader to the MIMO-OFDM system, in
Rayleigh frequency selective-channels. Orthogonal frequency
division multiplexing (OFDM) has been adopted in the wireless
local-area network standards IEEE 802.11a due to its high spectral
efficiency and ability to deal with frequency selective fading. The
combination of OFDM with spectral efficient multiple antenna
techniques makes the OFDM a good candidate to overcome the
frequency selective problems.
