On Enhancing a Hybrid Admission Control Algorithm for IEEE 802.11e EDCA

International audienceCall Admission Control is one of the main mechanisms allowing an efficient protection of active flows, especially on a wireless network using a distributed access scheme as is the case for IEEE 802.11e EDCA. We proposed in a previous paper [5] a hybrid admission control algorithm (based on analytical model and on measurements) for EDCA which have proven to perform well when compared to another reference algorithm. We present here general modifications to hybrid admission control algorithms. These modifications are applied to our proposed algorithm and analyzed via simulation. Analysis clearly shows the advantages of these modifications
