Pure ALOHA is used in a network with Poisson distributed traffic. The success probability, as defined in this given with P(successful access) = 0.05.
a) How large is the normalised channel access rate G, and the normalised success rate S (also
sometimes called throughput)?
b) From now, the maximum data rate C is considered with C = 96 kbit/s = 96·103 bit/s. All
packets that are transmitted have a size of 64 byte and every sender in the network sends
3 packets per minute on average. What is the average access rate g1 of a single sender?
What is the average access rate g and the normalised access rate G on the channel if there are 50, 500, and 5000 senders connected?
c) With the same values of part (b) above, what are the normalised success rates S50, S500, S500
in the case of 50, 500, and 5000 senders?
