A Network Delay Model based on IEEE 802.11 WLANs

摘要：

With the popularity of the IEEE 802.11 standards, many analytical delay studies for the Distributed Coordination Function (DCF) have been reported. In this paper, we address the problem of analyzing the additional idle durations that a tagged node needs to wait due to other nodes transmissions. Separating the distributed inter-frame space (I)IFS) and extended inter-frame space (EIFS) durations from the full time of a successful transmission, we provide a correct function analysis of the DIFS and EIFS durations and build a more accurate delay model for the IEEE 802.11 DCF. The theoretical analysis and simulation results prove that the proposed delay model is coincident with the real performance When the node number increases.
