Mobile Networks: MAC Protocols

This lecture covers MAC protocols in mobile networks, focusing on Reservation Based and Contention Based protocols. It explains FDMA and Code Division Multiple Access (CDMA), detailing how CDMA allows multiple users to transmit simultaneously with minimal interference. The lecture also delves into CDMA encoding/decoding, two-sender interference, and the properties of orthogonal codes. Additionally, it discusses Slotted ALOHA and Pure ALOHA efficiency, highlighting the advantages and disadvantages of each. Finally, it explores CSMA/CA in Carrier Sense Multiple Access with Collision Avoidance, emphasizing throughput efficiency and the impact of overhead on data transmission.
