Abstract :
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/IC of IEEE 802.11, it also improves the network\´s performance in decreasing the network\´s throughput significantly. Furthermore, it can enable different packets with different priority to access the media and thus gain QoS.
