Abstract
Quality of service (QoS) guarantees are becoming increasingly
relevant for mobile networks, too, as they have to support, e.g.,
more and more audio and video applications with real-time
requirements. Therefore, recent extensions of WLANs, namely IEEE
802.11e, are introducing new mechanisms to enable the provisioning
of QoS guarantees, in particular by means of resource reservation.
This paper suggests to diminish the inefficiencies of the resource
reservation approach as taken by IEEE 802.11e. The solution
advocated is to embed the authors' earlier abstract approach for a
dynamic resource redistribution into 802.11e based WLANs. By means
of analytical and simulation models it is demonstrated that the
extension of 802.11e based networks by a dynamic resource
redistribution can lead to a significant increase in overall network
utilization, though QoS requirements can still be guaranteed.
