Throughput Evaluation of CSMA Assuming Carrier Detection Probability in Wireless Ad Hoc Networks

In performance evaluations of wireless ad hoc networks, both successful data reception and carrier detection probabilities are assumed to be 1 within a circle with certain radius and 0 outside the circle. In real systems, however, those probabilities are gradually changes from 1 to 0 as the distance between a terminal and access point increases. In this paper, we evaluate the throughput of wireless ad hoc networks assuming successful data reception and carrier detection probabilities to be continuous functions of the distance between a terminal and access point. We also show that new additional factors which decrease the throughput will appear under these assumptions, compared to the case where only probabilities 1 and 0 are assumed
