Course Contents
MAC taxonomy
Concepts of MAC effecting its performance improvements in Wired/Wireless-LAN
Reduction of vulnerable period:
Pure-ALOHA to Slotted-ALOHA
Slotted-ALOHA to Carrier sensing multiple access (CSMA)
Back off
Collision detection: stop transmission of collided packet reduction of ineffective time
Addition of collision avoidance (CA) in CSMA in one of the case of wireless-LAN due to hidden terminal and unguided medium (simultaneous transmission and receiving by same node creates problem in collision detection due to very high sensitive receiver)
WiMax services
Network Architecture
Node architecture
MAC frame format
Scheduling algorithm
Bluetooth MAC
Simulation technique
