A Control Theoretic Approach for Throughput Optimization in IEEE 802.11e EDCA WLANs
The MAC layer of the 802.11 standard, based on the CSMA/CA mechanism, specifies a set of parameters to control the aggressiveness of stations when trying to access the channel. However, these parameters are statically set independently of the conditions of the WLAN (e.g. the number of contending stations), leading to poor performance for most scenarios. To overcome this limitation previous work...
متن کاملCall Admission Control in IEEE 802.11e EDCA-based WLANs
The random access MAC protocol of WLANs is a key aspect in the actual rapid deployment of WLANs. However, the lack of a hard centralized control of the transmission resources, complicating an efficient implementation of QoS mechanisms without losing the inherent advantages of the distributed access scheme. To solve this difficulties, the EDCA IEEE 802.11e proposal has been released but, critica...
متن کاملA control theoretic approach to achieve proportional fairness in 802.11e EDCA WLANs
This paper considers proportional fairness amongst ACs in an EDCA WLAN for provision of distinct QoS requirements and priority parameters. A detailed theoretical analysis is provided to derive the optimal station attempt probability which leads to a proportional fair allocation of station throughputs. The desirable fairness can be achieved using a centralised adaptive control approach. This app...
متن کاملFlow-level QoS guarantees in IEEE 802.11e-EDCA based WLANs
Wireless LANs provide a broadband and mobile access to Internet, allowing multimedia mobile services to become a reality by using an alternative network to actual cellular systems. Simultaneously, the Internet user behavior is evolving to include VoIP and P2P services to the already traditional Web browsing, file transfer or e-mail. However, in this scenario, WLANs show several performance limi...
متن کاملSaturated Throughput Analysis of IEEE 802.11e EDCA
IEEE 802.11e standard has been published to introduce quality of service (QoS) support to the conventional IEEE 802.11 wireless local area network (WLAN). Enhanced Distributed Channel Access (EDCA) is used as the fundamental access mechanism for the medium access control (MAC) layer in IEEE 802.11e. In this paper, a novel Markov chain based model with a simple architecture for EDCA performance ...
