Abstract

In this paper performance modeling for a mobile stations operating according to CSMA/CA with binary exponential back-off (BEB) is discussed. Unlike the previous studies we concentrate on delay and loss performance metrics experienced by individual stations. To obtain delay distribution of an arbitrary packet we use Geo(i)/G(i)/1/K queuing system representing the number of stations having a frame for transmission. In this system both arrival and service process depend on the number of active station. Delay distribution is obtained as a weighted sum of delay distributions in each state of the system. Individual performance metrics are obtained by formulating and solving a separate Geo/G/1/K queuing system.
