An Enhanced Backoff Method used between Mobiles Moving in Industrial 802.11
The purpose of this study is to discuss the exchanges between mobiles moving in an industrial environment. To reach this study, a simulation approach has been chosen to be used. The selection of relevant propagation model for the selected industrial site is based on several measurements. By adjusting the parameters of the various models, we decided to select the model recommended by the ITU under reference Pr1238 to use for our industrial indoor domain.
The second step is to minimize the exchange time between mobiles within an 802.11 cell. The optimization of this time was carried out by modifying the binary exponential aspect of the Backoff algorithm in order to reduce the access time of the radio medium.
