WiFi-based IoT applications need to accomplish one thing, whether they require a large bandwidth or not: WiFi Sniffing. WiFi, despite having a limited range, offers incredible bandwidth such that even applications like live streaming can be easily hosted over a WiFi network. It is highly critical for controllers in IoT devices to identify and connect with available WiFi networks and effectively communicate data packets over a secure channel. WiFi/WLAN is one of the most commonly utilized wireless solutions in home automation, smart farming, office automation, and Industrial IoT. MAC layer protocols like WiFi/WLAN, Zigbee, Bluetooth, and Ethernet are of prime importance in IoT applications.
