By considering a stand-alone WLAN system, some possible packet relaying strategies are proposed and compared. These strategies are based on the possibility of using a terminal in the WLAN as a relay point, following three different approaches, so that the path between source and final target is realized by means of hops on intermediate stations. The medium access protocol is a polling and the control is hold throughout a token. The performance evaluation is made through simulations, in which are taken into account some simple models for terminal mobility, traffic generation, propagation channel, modulation and retransmissions. The simulations have the purpose of showing the impact of the system parameters and making a comparison between the strategies introduced.

Abstract
By considering a stand-alone WLAN system, some possible packet relaying strategies are proposed and compared. These strategies are based on the possibility of using a terminal in the WLAN as a relay point, following three different approaches, so that the path between source and final target is realized by means of hops on intermediate stations. The medium access protocol is a polling and the control is hold throughout a token. The performance evaluation is made through simulations, in which are taken into account some simple models for terminal mobility, traffic generation, propagation channel, modulation and retransmissions. The simulations have the purpose of showing the impact of the system parameters and making a comparison between the strategies introduced.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
