IEEE 802.11 standard is largely used anywhere as a cheap way\nto access internet, but the majority of devices used does not provide a\nstandard way to manage them. Mobile stations competing for access point\nmay causes a general wireless network failure, known as the ââ?¬Å?MAC\nAnomalyââ?¬Â. It is presented here an access point with modified firmware, that\nmonitors wireless conectionsÃ?´s quality and has a programmable capability\nallowing to do network management in a standardized manner, using\nSNMP for example. In this article, embedded Linux ââ?¬Å?OpenWRTââ?¬Â installed\nin a very cheap and reduced size hardware was used. By means of Bourne\nshell script programming, it is possible to collect all important operating\nparameters and data of the access point. From this, its possible to gain\nconsiderable control over it. IEEE 802.11 (Wi-Fi) access point devices are\nrouters, while embedded Linux has routing capabilities. Thus, it is easy to\nimplement traffic policies by means of Bourne shell script programming.\nTraffic shapping is one of the acces pointÃ?´s capabilities successfuly tested\nand demonstrated in this study. MAC anomaly detection in IEEE 802.11\nnetworks can be easily implemented by means of scripts as well. It was\ncollected and plotted network throughput data, becoming possible to\nobserve MAC anomaly in visual charts. A mate mathic model to apply on\nthe collected data of network throughput is under study, aiming to identify\nthe anomaly through calculations. The object of the current study is to\nintegrate everything: Measurements of operation data (network throughput\nin Mbit/s), identification of the MAC anomaly and its immediate\nmitigation. The result was the conception of an integrated device to\nmeasure, identify and mitigate MAC anomaly in a test field and therefore\nrestore network throughput by representing a gain of 42.5216%.
