PURE ALOHA:
Vulnerable time:
Let us find the length of time, the vulnerable time, in which there
is a possibility of collision. We assume that the stations send fixed-length frames with
each frame taking T to send.
---------------------------------------------------------------------------------------------------------------------------------------------------
so in pure aloha
vulnerable time(VT)
VT = 2 * transmission time
OR
VT = 2 * prapogation time
i m confused?????????????????????
