Calculating throughput for slotted ALOHA
Consider a system generating 20 bit frames and connected through a shared 20kbps channel. Find throughput in percent if slotted ALOHA is used and frame rate is 1000 fps.

Data communication and networking by forouzan 12.7 Exercise
11. We have a pure ALOHA network with 100 stations. If $T_{fr} = 1 \mu s$, what is the number of frames each station can send to achieve the maximum efficiency. 12. Repeat Exercise 11 for slotted ALOHA.

UGC NET CSE | July 2018 | Part 2 | Question: 41
A slotted ALOHA network transmits 200-bit frames using a shared channel with a 200 Kbps bandwidth. Find the throughput of the system (all stations put together) produces 250 frames per second: 49 368 149 151

#Self Doubt
When we say that vulnerable time in pure aloha will be 2*frame transmission time.So what this frame transmission time?? My doubt is does frame transmission time= propagation time+transmission time … collision can also happen during propagation time ??

Applied Test Series
Suppose that the PURE ALOHA protocol is used to share a 50 Kbps satellite channel, suppose that frames are 1000 bits long. Find the maximum throughput of the system in frames/second. [Note: Assume K = 10^3, write the floor value of the answer]
