Question

A slotted ALOHA network transmits 200-bit frames using a shared channel with a 200-kbps bandwidth. Find the throughput if the system (all stations together) produces 1000 frames per second.

(a) 92 frames

(b) 368 frames

(c) 276 frames

(d) 151 frames

I got this question in semester exam.

I'd like to ask this question from Overview topic in chapter Wireless Network Security and Network Security Overview of Cryptograph & Network Security

Answer 1

Correct answer is (b) 368 frames

For explanation I would say: G =1 S=G×e−G=0.368 (36.8%)

Throughput = 1000 ×   0.0368 = 368 frames.
