Abstract
This paper presents an analytical model for the performance evaluation of an IEEE 802.11e network in non-saturation environments. We first characterize the probability distribution of the MAC layer packet service time. Based on the probability distribution model of the MAC layer packet service time, we then study the queuing performance of the wireless local area networks (WLANs) at different traffic loads based on the IEEE 802.11e MAC protocol. The numerical results show that we can choose a feasible number and bandwidth of the node which determines the system performance that a user demands.
Highlights
The widespread implementation of IEEE 802.11 as the standard for wireless local area networks (WLANs) has given reliability to the notion that WLANs may soon spread over a large number of multiservice communication networks
The hybrid coordination function (HCF) provides an efficient mechanism for centrally coordinated medium access and it uses the enhanced distributed coordination function (EDCF) for the distributed coordination of medium access
Based on the probability distribution model of the medium access control (MAC) layer packet service time, we study the queuing performance of WLANs at different traffic loads based on the IEEE 802.11e MAC protocol
Summary
The widespread implementation of IEEE 802.11 as the standard for wireless local area networks (WLANs) has given reliability to the notion that WLANs may soon spread over a large number of multiservice communication networks. The primary difficulty faced in the use of IEEE 802.11 in multiservice wireless networks is the lack of quality of service (QoS) functionality as required by real‐time voice and video applications [1] To resolve this problem, the IEEE 802.11 Working Group created Task Group E to design medium access control (MAC) layer QoS enhancements according to the IEEE 802.11 standard [2]. There have been attempts to construct a mathematical model for the throughput performance of IEEE 802.11e [4, 5] These papers do not present the queue analysis results. Based on the probability distribution model of the MAC layer packet service time, we study the queuing performance of WLANs at different traffic loads based on the IEEE 802.11e MAC protocol.
