thank you, I feel like this is the only Hidden Terminal Problem video on KZfaq that drew the Ven diagram correctly.

IKR, every other video keeps a shared area between the ranges of two nodes and have the audacity to say they cant detect each other

So useful, for a senior just starting to learn about multiple access, found it so logical ,everything works orderly, hope you well!

Explained perfectly. A sends a packet to its neighbor ( B ) asking for permission. B grants but sends this grant to all its neighbors so they know not to transmit and ruin the transmission. A will then transmit once the grant is received and all others will be silent until transmission ends.

What happens if A and C send RTS at the same time?

@HowTomakeitdone 7 жыл бұрын

Those two RTS packets will collide at B. B will not receive any of this because of collision packets will be destroyed.

@Mat-vb8er 5 жыл бұрын

@@HowTomakeitdone And they will time-out (different times), so they don't collide again.

I have to take a seminar tommmorow on this ....now i am super prepared after seeing ur video...i am also quite sure i could answer anybodyz questions too....but one thing the concepts in the comment section could ve been in the video itself na?? They were very essential info too...make sure u update dat too....if possible...

@soumyamitra7183 3 жыл бұрын

what if a and c both request a RTS ? then wouldn't CTS broadcasted mean that a and c both will be clear to send data and thus collision will occur?

Even though, A and C fail to detect collision, B actually could, right? So does that mean the collision is detectible?

@HowTomakeitdone 8 жыл бұрын

Node B will receive a garbled message (corrupted message) thus B would know that there were some interference during transmission from source. There is no provision of ACK/NAK. There will be collision on B but senders will not stop transmitting. This hidden terminal problem occurred if csma/cd is used. In CSMA/CD if sender doesn't sense any collision then it won't stop transmitting.

At 2:46 you said because of the limited range csmacd will not work. Don't you think it is actually because of the fact that all the 3 devices used the same channel here and medium is shared in wireless?

@N00BRIUM 8 жыл бұрын

nicely explained. How will C know that it can send the data now?

@HowTomakeitdone 8 жыл бұрын

+N00BRIUM When A requested B by sending RTS, at that time B replied using CTS that CTS packet contain duration for which their communication will continue. Now this packet also received by C and C would know that duration of A and B conversion. So C will try after that duration by sending RTS packet to B.

@niharikaepuri3305 7 жыл бұрын

In the example that you have given, CTS will contain communication duration between A and B right?

@HowTomakeitdone 7 жыл бұрын

Yes, communication duration is contained in packet.

what if rts packets are sent simultaneously from a and c again, wont they collide again just as the data collided?/

@HowTomakeitdone 7 жыл бұрын

Yes they will if come to same node.

@robw475 5 жыл бұрын

it is quite hard for the RTS packets or CTS packets to collide as they are extremely small but there is a super small chance.
