Все измерения произведены средствами испытательного стенда, включающего в себя несколько точек доступа WiFi, WiFi-контроллер и WiFi-анализатор сети. В результате проведения более 900 испытаний в 19 различных условиях установлена зависимость между мощностью принимаемого сигнала RSSI и выбором предпочтительной точки доступа. Предложены параметры Channel Utilization и STA count в качестве дополнительных критериев, влияющих на выбор оптимальной точки доступа.</p></abstract><trans-abstract xml:lang="en"><p>This paper analyzes WiFi access point selection mechanisms used by IoT WiFi devices. A testbed for experimental setup is proposed. The testbed includes several WiFi access points, WiFi controller and WiFi network analyzer. More than 900 measurements covering 19 test cases are made. It is shown that an received signal strength indicator is the primary criterion used by the IoT WiFi device for access point selection during connection procedure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>WiFi</kwd><kwd>точка доступа</kwd><kwd>IoT</kwd><kwd>RSS</kwd><kwd>экспериментальный стенд</kwd></kwd-group><kwd-group xml:lang="en"><kwd>WiFi</kwd><kwd>access point</kwd><kwd>IoT</kwd><kwd>RSSI</kwd><kwd>testbed</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zanella A., Bui N., Castellani A., Vangelista L., Zorzi M.
