Efficiency Of Slotted Aloha = 36.8%
Throughput = Efficiency * Bandwidth
= 0.368 * 60Kbps
= 22.08Kbps
Now, this is the throughput of entire channel…
According To Question,
1024 bits are transferred every 40 secs. Also throughput of each station is bits transferred every second
Throughput of Each Station = 1024/40
= 25.6 bits/sec
Let the channel have N stations, each having a throughput of 25.6 bits/sec, then
N * 25.6 bits/sec = 22.08Kbps
N = 22080 bps / 25.6 bps
N = 862.5
Taking the lower bound or floor value as we can’t have half station, Total Number of Stations
N = 862
