摘要：

We design a cooperative retransmission scheme in the MAC layer which utilizes the UWB unique properties such as fine ranging and immunity to small scale fading in order to exploit the multiuser diversity in UWB networks. We analyze the optimal cooperation strategy to maximize the system throughput in proactive and reactive settings. We also perform simulations to show that the proposed UWB-based Coperative Retransmission Scheme, (UCoRS), achieves a considerable diversity gain in spite of its implementation simplicity. UCoRS also minimizes the number of control packets that is required for cooperation In order to provide energy efficiency in the UWB receivers.
