Experimental Testbed for Access Point Selection in IoT WiFi Networks

Abstract

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.
