Question

Describe the steps involve in a Distributed Coordination function using a simple carrier sense multiple access algorithm with an interframe space delay to transmit frames in a Wireless LAN.

Answer 1

Distributed Coordination Function is the common mode used to transmit the physical medium. Mostly, it is used in both cases of infrastructure networks and ad hoc. Any Wi-Fi device must have an implementation of this mode. The DCF corresponds to an advanced version of Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA).
