Abstract :
We investigate a new collision-free MAC protocol for ad hoc wireless networks, namely carrier sense media access/ID countdown (CSMA/IC), which can achieve 100% collision-free performance by solving both the "hidden terminal" and the concurrent sending problems. Furthermore, we propose an efficient ID assignment mechanism for CSMA/IC. With the new ID assignment mechanism, the length of the medium competition period before data transmission is greatly decreased. This further leads to an increase in network throughput, especially in high speed wireless networks.
