The accuracy of a DFIL system is depreciated, as the change in the indoor environment due to furniture and other infrastructure movement. This paper investigates the development of testbed of the WLAN network for measuring the RSSI in various indoor environment, as the initial step for designing the fingerprinting-based algorithms for WLAN network. The database of RSSI fingerprint is created initially and then a fingerprint-based algorithm is developed for locating the position of a human body in the indoor environment. The localization algorithm tests the minimum distance in the RSSI values related to the different test points in the indoor environment. This work further demonstrates that how the fingerprints of RSSI are collected and which network configurations generate the most reliable RSSI measurement. For the first phase of designing the testbed, the configurations of different equipment and various tools are elaborated in the indoor environment. For the second phase the RSSI is measured in different propagation indoor environment. The extensive experiments were performed that allow quantification of how changes in an environment affect accuracy. Thus, it is demonstrated that each link offers a viable approach to developing a more robust system for device-free localization that is less susceptible to changes in the environment. © 2016, Springer Science+Business Media New York. date: 2017 publisher: Springer New York LLC official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85006377750&doi=10.1007%2fs11277-016-3902-8&partnerID=40&md5=6d86b7fc2bab4f9c0cf19c4211746ee7 id_number: 10.1007/s11277-016-3902-8 full_text_status: none publication: Wireless Personal Communications volume: 95 number: 2 pagerange: 445-455 refereed: TRUE issn: 09296212 citation: Pirzada, N. and Nayan, M.Y. and Subhan, F. and Abro, A. and Hassan, M.F. and Sakidin, H.
