| Abstract: | Wi-Fi based IoT devices are deployed for a wide variety of different applications, with each application requiring different Quality of Service (QoS) guarantees. While the IEEE 802.11e amendment to the Wi-Fi standard specifies additions that enable QoS, only 4 traffic categories are defined with hard-coded properties in the standard. This improvement is insufficient for meeting the diverse QoS requirements in IoT networks. A novel solution of Wi-Fi slicing, which allows for the network to be divided into an arbitrary number of slices, with the priority of each slice being defined by a quantum value representing the relative fraction of airtime allocated to the slice. However, the current implementation of said architecture lacks robust control over network slice configuration parameters. The aim of this paper is to ameliorate control over slices by including channel access parameters from the WiFi MAC layer in addition to quantum values. Our proposed scheme enables improved network slicing capabilities in SDN-controlled Wifi networks in addition to providing superior QoS capabilities. |
