Technologies in wireless networks are the result of years of constant developments in the field of technology and electric. Wireless networks increasingly popular because of their low cost, fault tolerance, ease of use, operation, and today it is present in the daily life of modern civilization. To add value to these networks, studies in the areas of location of devices connected to these networks, location-based services have been investigated in recent studies, since open perspectives for new applications. In this type of application services can be offered to the user só that input parameters and / or output are directly influenced by their fixed position. This is a very broad area of operation where problems related to location and positioning can be attacked in different ways. This paper proposes a system of tracking devices for wireless local area networks based on radio frequency characteristics of these networks. This work aims to contribute to the area presenting a practical solution of location for these networks using only the signal strength as an input parameter. This solution was implemented and tested in a real environment, resulting in a probabilistic algorithm that estimates the location in wireless networks. This algorithm is based on the free-space path loss formula (FSPL) and achieved results of satisfactory accuracy, approaching the real position. |
