Abstract: In this paper we analyze the effects of the probabilities of detection, of false alarm, and of frame survival (in the presence of simultaneous transmissions) on MAC protocols using impulse radio-ultra wideband (IRUWB) energy collection non-coherent receivers. The MAC protocols considered are all IEEE 802.15.4 compatible, namely the IEEE 802.15.4a optional UWB CCA mode, the IEEE 802.15.4a ALOHA mode, and a protocol termed preamble sense multiple access (PSMA). The impact on the network throughput, energy consumption, and delay are derived analytically and verified by simulation. The results show that these effects have a considerable impact on the performance of IR-UWB MAC protocols and a classical analysis does not properly evaluate the protocols performances. The results compare the performances of the MAC protocols as well as highlight a number of issues regarding adapting narrowband protocols to UWB systems. The probability of frame survival on simultaneous transmissions is shown to have a significant impact on a MAC protocol performance. The comparison shows superior performance of the PSMA protocol under
