摘要：
In this letter, we present a random access protocol with success priority, success prioritized distributed coordination function (SP-DCF), based on IEEE 802.11 DCF. Success stations (STAs) are prioritized contentionlessly to transmit the next data frame in the transmit queue in a random manner. We develop a performance analysis model of SP- DCF which enables us to estimate a variety of performance indexes such as the throughput or the frame discard rate (FDR) in a high accuracy for saturated wireless networks. The numerical analysis and simulation results show that the proposed SP-DCF achieves higher throughput and lower FDR as compared with the conventional DCF especially for heavily-congested wireless networks.
