Abstract :
We propose a two-dimensional (2D) Markov model, which considers packet losses, for carrier sense multiple access with collision avoidance (CSMA-CA) mechanism. Since the initial contention window (ICW) has great impact on the performance of CSMA-CA, we introduce an adjustable state parameter q(0\n\n\t\t
