A large population of ALOHA users manages to generate 50 requests/sec, including both originals and retransmissions. Time is slo

krok68 [10]

Answer:

The answer is below

Explanation:

Given that:

Frame transmission time (X) = 40 ms

Requests = 50 requests/sec, Therefore the arrival rate for frame (G) = 50 request * 40 ms = 2 request

a) Probability that there is success on the first attempt = $e^{-G}G^k$ but k = 0, therefore Probability that there is success on the first attempt = $e^{-G}=e^{-2}=0.135$

b) probability of exactly k collisions and then a success = P(collisions in k attempts) × P(success in k+1 attempt)

P(collisions in k attempts) = [1-Probability that there is success on the first attempt]^k = $[1-e^{-G}]^k=[1-0.135]^k=0.865^k$

P(success in k+1 attempt) = $e^{-G}=e^{-2}=0.135$

Probability of exactly k collisions and then a success = $0.865^k0.135$

c) Expected number of transmission attempts needed = probability of success in k transmission = $e^{G}=e^{2}=7.389$
