Abstract :
This paper addresses a distributed throughput- optimal CSMA for wireless networks, which is called the preemptive CSMA. Distinguished from other throughput-optimal CSMAs in the literature, it achieves the optimality even with the throughput loss caused by discrete backoff time, non-zero carrier sense delay and data packet collisions. Moreover, the analysis on the preemptive CSMA provides the understanding on the relationship among the throughput-optimal CSMAs.
