The Context-Aware applications, need adaptations to the environment in which they are inserted. For this reason, they need information about the devices and external factors. This work proposes a model to describe and to forecast, in real time, the channel behavior of WLAN IEEE 802.11 networks.The model evaluates the indicators of channel quality and, using a technique based on exponential smoothing, makes their forecast. The obtained results show that the proposed model outperform those from Trigg and Leach model.
