a Name and explain the responsibilities of each MAC sub laye

a. Name and explain the responsibilities of each MAC sub layer.

b. Explain the following MAC layer terms: MSDU, MPDU, and Convergence.

Solution

Multiple Access Protocols

Random Access Protocols:

.It is also called Contention Method.

Controlled Access Protocol

Channelization Protocol

MPDU –MAC protocol data unit, MSDU- MAC service data unit.

A MPDU concatenates upto 64 MAC protocol data unit subframes into a single physical layer service data unit provided that all all constituent MPDUs are destined to the same receiver.

Convergence sublayer is a different higher layer protocol are implemented in different sublayer.
