The SIFS( Shortest Inter-Frame Space),derives the time between the last transmission and high priority transmissions such as positive acknowledgments(ACKs),Clear-To-Send(CTS)frames,polling responses, continuation frames in a burst transmission. priority is given to the positive ACK frames so that a station which has just completed the reception of a frame can give immediate feedback to the sender. RTS and CTS frame coordinate correspondence between sets of stations so that different stations know not the medium to be free for the time of the exchange .This is one of the reasons for why the control frames have priority over normal data transmissions. If a station finished transmitting a frame and has enough time left to send an additional frame, it is allowed to send after a SIFS. …show more content…

The DIFS, or DCF Inter-Frame Space, is the base time taken by any station yet not the organizer must hold up to transmit. On the off chance that the medium is detected to be free, after a DIFS, a station may begin decrementing its backoff counter. The PIFS is shorter than the DIFS so that the central coordinator can take control of the network whenever The EIFS, or Extended Inter-Frame Space, is the minimum wait time for a station that receives corrupted frames or other errors. The EIFS is frequently variable relying upon the type and number of mistakes. Prior to the station has the opportunity to transmit once more, the EIFS time is intended to give another station time to ACK the casing that was gotten and deciphered as degenerate. In the event that a legitimate casing is gotten before the EIFS has terminated, the EIFS clock is dropped since ordinary synchronization with the system has
