Abstract

This paper evaluates the viability of using the SNR (signal-noise relation) variation in infrastructured IEEE 802.11 networks for micro-mobility characterization. Using measures that verify the SNR variation in stations with micro-mobility, the paper presents an algorithm to allow a station to make a micro-mobility self-identification procedure and then, may be able to activate a mechanism to diminish management and control frames that verify continuously the connection with the AP (Access Point). The experimental results verify that with several degrees of nodes movement is possible to identify the micro-mobility based in two parameters: the SNR variation and the prevalence with the AP.
