Dear All, In "ECS: an Enhanced Carrier Sensing Mechanism for Wireless Ad-hoc Networks" Paper. Authors proposed we can select Best Value For EIFS Based on Frame Length.
We know : RTS: 20 bytes, CTS: 14 bytes,ACK: 14 bytes. But Frame length CTS and ACK is Equal. Authors proposed we can increase CTS value to 17. 1- But,How can we do this change in NS2.27? On Next step: Based on Frame length we select a good Value for EIFS: Proposed Values : EIFS(RTS) = SIFS + TxTi m e (CTS ) ; EIFS(CTS)=SIFS+TxTime(Max-Data-Length) ; EIFS(Data)=SIFS+ TxTime(ACK ) ; EIFS(ACK) =DIFS ; EIFS(collisionorunknowntype) =StandardEIFS ; Example if we Receive a frame(it s size equal with 14 bytes)We can find out this frame is ACK Frame and Best Value for EIFS is DIFS. 2- Can you bring me or guide me How can i implement these condition statements? I m appreciating that hear from you as soon as possible kind Regards Hamid Reza ____________________________________________________________________________________ Get your own web address.
