Abstract

The throughput of the Elimination Yield Non-pre-emptive Priority Multiple Access (EY-NPMA) protocol, which has been chosen as the medium access control (MAC) protocol for HIPERLAN, is simulated. Connection between users is based on a statistical model of path loss with power law against distance and 6 dB log-normal shadowing. It is shown that the throughput performance of the EY-NPMA protocol in networks of moderate size and with small proportion of hidden nodes is satisfactory. For a fully connected network, the throughput reaches 0.85 at an offered traffic of 1 and remains at this level. The maximum throughput reduces gradually when the number of hidden node pairs in the network is increased. With 11% of hidden nodes in the network the peak throughput falls to 0.6.
