18 Questions
What does CSMA/CA stand for in wireless communication?
Carrier Sense Multiple Access with Collision Avoidance
What is the purpose of the Distributed inter frame Space (DIFS) in CSMA/CA?
To wait for the end of the current transmission
What happens if other Mobile Stations (MSs) transmit during the backoff time in CSMA/CA?
The receiving MS freezes its backoff counter
When can a Mobile Station (MS) start its transmission in CSMA/CA?
After DIFS period ends
What does CSMA/CA allow terminals to do in case of channel contention?
Wait for a random time and then transmit
In CSMA/CA, why does a Mobile Station defer to another if it senses the medium is busy?
To avoid interference and collisions
What is the main characteristic of p-persistent CSMA protocol?
It transmits with a probability p when the medium is idle
Which special case represents 1-persistent CSMA?
p=1
What is the tradeoff provided by p-persistent CSMA protocol?
Between persistent and nonpersistent CSMA
At which probability value does the persistent CSMA have to wait for T units before transmitting?
$p=0$
In terms of throughput, which type of CSMA has the highest efficiency?
$p=1$ persistent CSMA
What happens if the medium is busy in p-persistent CSMA protocol?
Continue to listen until medium becomes idle
What is the main issue when more than one Mobile Station (MS) transmits at the same time on the control channel to BS?
Collision
Which protocol resolves a collision after it occurs in a multiple access system?
CSMA/CD
What type of protocols aim to solve multiple access issues in wireless communication systems?
Contention-based Protocols
In a wireless system, what happens if more than one Mobile Station (MS) attempts to transmit data simultaneously?
Collision
Which protocol is designed for Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) in wireless networks?
Bounded ALOHA
What is the primary issue when several Mobile Stations (MSs) share the same communication channel?
Collisions
This quiz covers the p-persistent CSMA (Carrier Sense Multiple Access) Protocols. It includes steps for transmitting data when the medium is idle or busy, along with special cases. Test your knowledge on the operation of p-persistent CSMA in wireless and mobile systems.
