Analysing the performance of WLANs in non-ideal channel conditions is a fundamental consideration in practical situations since wireless channels are error-prone. This paper presents a closed form analytical solution for the non-saturated throughput of a QoS differentiated p-persistent CSMA protocol that takes into account the capture effect in a Rayleigh multipath fading environment. The results...
In this paper, a comprehensive and new closed form analytical approach to calculate the saturated throughput and delay of a differentiated p-persistent CSMA protocol with a multirate capability is presented for the first time. The p-persistent analysis can be used to model accurately 802.11e EDCA for WLAN applications. The analysis allows 802.11e to be characterised in the case of multirate operation...
With the rapid development of 802.11 wireless local area networks (WLANs) and the need for better quality of service (QoS) the 802.11e MAC with service differentiation was developed. Analysing the effect of transmission errors on the performance of 802.11 is a fundamental consideration in practical situations since the wireless channels are error-prone. This paper modifies the p-persistent CSMA protocol...
With the extensive deployment of 802.11 wireless local area networks (WLANs) and the need for better quality of service (QoS), the 802.11e MAC with service differentiation was developed. Analysing the effect of fading, shadowing and near-far effect on the performance of 802.11 is a fundamental consideration in practical situations since the wireless channels are errorprone.This paper develops a p-persistent...
