− In this paper, we analytically analyzed the impact of an error-prone channel over all performance measures in a trafficsaturated IEEE 802.11 WLAN. We calculated station’s transmission probability by using the modified Markov chain model of the backoff window size that considers the frame-error rates and maximal allowable number of retransmission attempts.(More)
In this paper, we estimated the influence of capture effect over the capacity of IEEE 802.11b DCF within a single picocell. The channel utilization is examined analytically by introducing two capture models based on Rayleigh-distributed envelopes of the captured and the interfering frames divided into two local-mean power classes. Simulations in a pure(More)
In this paper, we analytically analyzed the influence of capture effect over theoretical throughput and delay of a traffic-saturated IEEE 802.11b BSS in Infrastructure and Ad-hoc configurations. The capture probabilities are derived in presence of near/far effect and/or Rayleigh fading, i.e. with or without power control mechanisms. The peak aggregate(More)
