A 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 کاملAchieving proportional fairness with a control theoretic approach in error-prone 802.11e WLANs
This letter proposes a control theoretic approach to achieve proportional fairness amongst access categories (ACs) in an error-prone EDCA WLAN for provision of distinct QoS requirements and priority parameters. The approach adaptively adjusts the minimum contention window of each AC to derive the station attempt probability to its optimum which leads to a proportional fair allocation of station...
متن کاملA 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 کاملMeta-heuristic approach to proportional fairness
Proportional fairness is a concept from resource sharing tasks among n users, where each user receives at least 1/n of her or his total value of the infinitely divisible resource. Here we provide an approach to proportional fairness that allows its extension to discrete domains, as well as for the direct application of evolutionary computation to approximate proportional fair states. We employ ...
