In this paper, the authors 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. Next, 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 papers. This new scheme uses a smart Loss Function to dynamically regulate the contention window, hence they call it DDPA (Dynamic dropped packet algorithm, which s (a limitation of present EDCA scheme).
