100 stations on a pure ALOHA network share a 1Mbps channel. If frames are 1000 bits long, find throughput if each station is sending 10 frames per second.

Throughput of pure aloha ,S=G × $e^{-2G}$. Where G is the average no. Of frames generated by system during one frame transmission time.

Transmission time =$\frac{frame size} {bandwidth}$=$\frac{1000 bits}{1Mbps}$=1 ms.

If a station create 10 frames per second  means 100 stations(system) will create $1$ frame  per millisecond ,so G= $1$

$S = G×e^{-2G} = 0.135$

$0.135 \times 1Mbps =  135 Kbps$
