Answer:
The answer is 0.08192%.
Explanation:
1 byte consists of 8 bits so for a total packet length of 1024 bytes, there are 8192 bits. The channel has a bit error rate of 0.00001 or 0.001%.
For each data packet transmitted with no overhead, the packet error rate (PER) would be 0.0008192 or 0.08192%. for each single round of packet delivery.
I hope this answer helps.
Following are the calculation to the final average probability of packet error:
bit error rate= [tex]0.00001[/tex]
The packet length is [tex]=1024\ bytes[/tex]
A byte is[tex]= 8\ bits.[/tex]
As just a result, the overall bit size of the packet is [tex]1024 \times 8 = 8192\ bits.[/tex]
As just a result, for each packet header transmitted with really no overhead,
[tex]PER = 0.00001\times 8192 = 0.08192[/tex]
As just a result, [tex]8.192\%[/tex] of the packet will be damaged.
When [tex]8.192\%[/tex] of damaged transmissions have indeed been retried, then [tex]8.192\%[/tex] of try packets will fail as well.
This indicates that [tex](0.08192)^2[/tex] will fail.
[tex]\to (0.08192)^2 = 0.00671[/tex]
As just a result, with a single retry,[tex]0.671\%[/tex] of all packets would fail. We may just multiply them together as each retry is an individual probability.
