Abstract

In this paper, field research was conducted in order to enrich and strengthen the “NetArgus” application that is able to monitor either a wired or a wireless network with all its possible aspects. Original algorithms were implemented in an effort to find the position of a moving station utilizing the signal level of wireless local area network (WLAN) devices. Exhausting sampling and research were done, in order to resolve various practical problems associated with the signal level of the wireless stations as well as the involved hardware. Various flaws and omissions of 802.11x protocols were discovered, such as the lack of definition of the signal level and its width range. Moreover, a plethora of positioning practical problems has been adequately managed. Hence, an application was constructed to draw paths and manipulate proper information from various network moving clients, using the Simple Network Management Protocol (SNMP) as well as low level operating system libraries. Last but not least, “Kalman Filter” was implemented and fully tested in order to correct the positioning unavoidable mistakes.
