In this paper, we present a new collision-free MAC protocol-Carrier Sense Media Access with ID Countdown (CSMA/IC) for ad hoc wireless networks that can achieve 100% collision-free performance by solving the "hidden terminal" problem and the concurrent sending problem. Compared to CSMA/CA of IEEE 802.11, it also improves the network's performance in decreasing the average delay of packet sending, dropping discard ratio, and increases the network's throughput significantly. Furthermore, it can
more » ... rthermore, it can enable different packets with different priority to access the media and thus gain QoS. I.
