What are the basic differences between CSMA/CA and CSMA/CA with RTS/CTS?
Answers
Answer:
Explanation:
1.CSMA CD initializes it's effect after a collision between data is detected while CSMA CA takes into effect before a collision is even found.
2.CSMA CA minimises the chances of a data collision while CSMA CD only reduces the recovery time of the selected data.
3.CSMA CD is broadly used in wired networks or connections while CSMA CA is majorly used in wireless distribution of network.
When it comes to RTS/CTS or rather CTS-to-self it is an extensive option in 802.11 for quite a few reasons. Firstly as because it is a very part of the protection mechanism that allows older 802.11 devices and also the newer 802.11 devices to communicate properly between them especifically for 802.11b or the earlier devices with the 802.11g or even the later devices as many DSSS devices would not be able to realise OFDM traffic as just another 802.11 device. It is used to resolve various different no of different issues. However owing to it's significant impact on performance of 802.11 it is not recommend to use it, if there's a way you can avoid it. CSMA/CA is readily used for 802.11 traffic system whether you use RTS/CTS or not.
