Packet Delay Modeling of IEEE 802.11 Wireless LANs

چکیده
This paper presents a new analytical model for calculation of the average packet delay of the IEEE 802.11 Distributed Coordination Function assuming ideal channel conditions. The new model applies to both basic and Request-to-Send / Clear-to-Send access modes and is based on calculating the average delay of packets successfully transmitted after a specific number of collisions and the corresponding probability. Results indicate that the proposed model is more accurate than a model proposed in the literature that calculates the same components. The accuracy of another model presented in the literature that evaluates the time delay at each backoff stage is studied.

Performance of wireless LANs based on IEEE 802.11 MAC protocols
IEEE 802.11 MAC protocol has been the standard for Wireless LANs, and also adopted in many network simulation packages for wireless multi-hop ad hoc networks. However, it is well known that, as the traffic goes up, the performance of IEEE 802.11 MAC drops dramatically in terms of delay and throughput, especially when the station approaches its saturation state. To explore the inherent problems ...
