EDCA， HCCA，IEEE 802.11e
We investigate the problem of efficient resource
control for elastic traffic over the EDCA (Enhanced Distributed
Channel Access) and HCCA (Hybrid Coordination Function -
HCF - Controlled Channel Access) mechanisms of IEEE 802.11e.
Our approach considers an economic modelling framework based
on congestion pricing that captures how various factors, such as
the probability of attempting to transmit a frame, the transmission
opportunity (TXOP), and the physical layer transmission
rate, contribute to congestion. Additionally, we consider the joint
control of the EDCA and HCCA mechanisms, which allows us to
determine the optimal sharing of the wireless channel between
the two access mechanisms.
