%X An Impulse Radio UWB (IR-UWB) system uses very narrow pulses with time-hopping and time diversity to transmit data, where the signals have very low duty cycle. In this paper the cause of data frame transmission failure is analyzed in a distributed IR-UWB network using the ALOHA protocol, and the failure probability is derived. Based on queuing analysis of the data frame generating-buffering-sending process, the network throughput and frame transmission delay in closed-form expressions are obtained. Simulation results show that the throughput, frame transmission delay and stability of the ALOHA IR-UWB network is much better than those of the ALOHA network based on carrier modulation technology.
