The study of the impact of a self-similar traffic, with respect to that of a Poisson classical one, on ad-hoc Wireless LAN systems is performed. The self-similar traffic generation is obtained by using a chaotic system, with structural parameters varied in order to have different self-similarity degrees and activity factors, and to permit a correct comparison with the Poisson traffic. The WLAN systems considered are based on polling MAC protocols and on different packet delivery strategies. In the performance analysis, obtained by means of simulations, some simple models for channel impact, retransmission strategy and terminal mobility are taken into account.

Abstract
The study of the impact of a self-similar traffic, with respect to that of a Poisson classical one, on ad-hoc Wireless LAN systems is performed. The self-similar traffic generation is obtained by using a chaotic system, with structural parameters varied in order to have different self-similarity degrees and activity factors, and to permit a correct comparison with the Poisson traffic. The WLAN systems considered are based on polling MAC protocols and on different packet delivery strategies. In the performance analysis, obtained by means of simulations, some simple models for channel impact, retransmission strategy and terminal mobility are taken into account.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
