Pure Aloha

Question

An aloha network user $19.2 \text{ kbps}$ channel for sending message packets of $100 \text{ bits}$ longsize. calculate the maximum throughput for pure aloha network.

Answer 1

we know that for pure aloha efficiency = $G \times e^{-2G}$

and in the maximum case we find it to be $0.184$

throughput=efficiency $\times$ Bandwidth

=$.184*19.2=3.5328kbps$

if we find it in packets/sec then,3.5328/packet size=3.5328/100=.035328 kilo packets per second
