Please help me with Wireless and Mobile Networks question

Assignment Considering a WiFi network consisting of 1 AP and 4 STAs all using 802.11ac standard, each device is using a variant of Minstrel algorithm when selecting their MCS level to communicate. The variant has two differences with the base Minstrel algorithm: a. retry counts are selected as (3=1, other c values are selected as 0;29+1 and Ec;=retry_count where the total retry count depends on the size of the frame a. For long frames (frames bigger than 1000 byte), retry_count = 7 b. For short frames (frames smaller than 1000 byte), retry_count = 4 b. For short frames, a shorter retry chain is calculated by using, ra r1, and 13. Based on these two rules, raw data rates, current retry chain, and current Minstrel parameters as given below, calculate the MCS levels AND retry counts in the next retry chains (both the long and the short version) 0 1 2 3 4 5 6 7 8 9 MCS Level 15 30 45 60 90 120 135 150 180 200 Raw Data Rate Current retry chain (long): {(MC59,3), (MC58,2), (MCS2,1), (MCSO, 1)} Current retry chain (short):{(MCS9,2), (MC58,1), (MCSO, 1)} N 3 4 5 6 7 8 9 MCS Level 0 1 Psuccess (t) 1 1 1 0.97 0.96 0.9 0.8 0.78 0.97 0.95 nisuccess(t+1) 73 | 700 09 6 11 00 14 8 8 406 634 Mtota(t+1) 73 700 6 12 8 15 9 1000 1400 Assignment Considering a WiFi network consisting of 1 AP and 4 STAs all using 802.11ac standard, each device is using a variant of Minstrel algorithm when selecting their MCS level to communicate.
