Experimental results for a proposal of adaptative mechanism based on SNRs variation in infrastructured wireless networks

Abstract

This paper presents the experimental results in a proposal that aims to develop an adaptive mechanism of management and control frame traffic under a infrastructured network in the IEEE 802.11 standard to any of its versions. The mechanism is based on Signal-to-Noise Ratio (SNR) values to measure users mobility and allow the station to decide the mechanism activation or deactivation. Preliminary results were obtained from two propositions: a) indoor measurements of a WLAN 802.11g placed inside the Computer Science Center (CIC) at the University of Braslia (UNB) which covered the area of the computer labs. b) a previous simulation of the adaptive algorithm in MATLAB with nodes operating within the proposed mobility characteristics as a case study in order to test auto-activation or auto-deactivation of the mechanism by the station.
