ABSTRACT
In this paper we propose an adaptive transmission algorithm over an IEEE 802.11 WLAN that supports integrated voice and data services, where data traffic is transmitted with the Distributed Coordination Function (DCF), while voice transmission is carried out with the Point Coordination Function (PCF). The proposed algorithm defines an updating period. At the beginning of each period and based on the transmission statistics of the previous one, our algorithm adjusts the protocol parameters to improve data transmission without compromising voice transmissions, i.e., maximum allowable delay is respected. To show the efficiency of the proposed algorithm, we compare it with a previous work we did in [13]. The simulation results are provided and show the advantage of using such algorithm in term of protocol performance.
