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 multi-user diversity as well as cooperative diversity. It even makes a fair scheduling possible. Performance analysis is done analytically and by means of simulation.
