Wireless cooperative networks

Relay selection is a new method currently used to develop and improve
cooperative wireless networks. One of the main advantages of this new
technology is that it can achieve cooperative diversity gain without installing
multiple antennas in the transmitter or receiver. Relay selection algorithms
can be used to select one node to become a relay node from a set of N
candidate relays with optimization criteria as the outage probability or frame
error rate. The selection process is preferable to operate in a distributed
fashion and offers only reasonable costs in terms of manufacturing
complexity and flexible handling over wireless cooperative networks. In this
work, different relay selection schemes are proposed to enhance the
cooperative wireless networks in terms of different approaches including: 1)
relay selection-based destination feedback scheme, 2) relay selection based a

ready-to-send/clear-to-send (RTS/CTS) messages scheme, 3) relay selection-
based identification messages (IDM) table scheme, and 4) relay selection-
based relay power consuming scheme. The experimental results via

suggested case study show that the performance of overall cooperative
network is enhanced in terms of increasing throughput, energy saving
(efficiency maximization), blocking reduction and outage reduction (PER
minimization).
