Channel adaptive scheduling for cooperative relay networks

We consider a wireless network consisting of several active source/destination pairs and several idle nodes. All nodes are equipped with one antenna. The communication between source/destination pairs takes place over two-hop links. Idle nodes are used as amplify-and-forward relays assisting the communication. We investigate the benefits and potential of joint cooperative diversity and channel adaptive scheduling in such a network. We show that this scheme is able to exploit multiuser diversity as well as cooperative diversity. It even makes fair scheduling possible. Performance analysis is done analytically and by means of simulation.
