Dynamic Dropped packet regulation of contention window for enhancement of IEEE_802.11e

In this paper we present a new scheme which is mend to increase the efficacy of the present EDCA, and also make EDCA more robust in a high noise environment, where high packet loss is characteristic. This paper provides a brief account of EDCA mode; it also informs about limitations of present EDCA scheme. Nex t , paper postulates a more robust scheme; this newly proposed scheme exploits already known facts (potential but yet unutilized) which were presented in previous standards, journals or other kind of research articles. This new scheme uses a smart Loss Function to dynamically regulate the contention window, hence we call it DDPA (Dynamic dropped packet algorithm, which s (a limitation of present EDCA scheme). This DDPA will make access stations (participating in EDCA )more immune against the packet starvation.
