Relaying is seen as an advanced technique to improve
the throughput, to exploit the spatial diversity, and
most importantly to increase the coverage area in
wireless networks. This work proposes several
signaling protocols in relay networks and analyzes
the performance limits of these protocols. It is
shown that compared to a non-cooperative mode of
transmission, throughput and/or reliability are
immensely enhanced. The reader of this work will get
familiar with the principles of relay networks. A
summary of the techniques used in relay networks is
first provided. The relaying schemes of
decode-and-forward and compress-and-forward are
studied within a novel generalized relay channel
model. Then, the idea of relay selection is
highlighted and two novel relay selection schemes are
presented. Finally, relaying in interference networks
is considered, where multiple source-destination
pairs attempt to communicate together and they are
assisted by a dedicated relay station. The protocols
presented in this work have applications in military
communications, ad-hoc and sensor networks, and
broadband wireless systems.
