Selective Retransmission Solution

STEP 0: Pre-Calculation Summary
Formula Used
Selective Retransmission = (Number of Word Message Consist*Information Bits)/(Header Bits*Expected Number of Transmission+Number of Bits per Word*Expected One Transmission*Number of Word Message Consist)
Rs = (Nwd*L)/(H*En+Bwd*E1*Nwd)
This formula uses 7 Variables
Variables Used
Selective Retransmission - Selective Retransmission also called Selective Repeat ARQ (Automatic Repeat Request), is a data link layer protocol that uses the sliding window method for reliable delivery of data frames.
Number of Word Message Consist - Number of Word Message Consist in a message can vary depending on the specific protocol and encoding scheme being used.
Information Bits - Information bits refer to the fundamental units of data that are transmitted and received between devices or systems.
Header Bits - Header bits refer to the bits of information included at the beginning of a data transmission packet or frame.
Expected Number of Transmission - Expected Number of Transmission refers to the average number of times a packet or data transmission needs to be sent from a transmitter to a receiver in order to achieve successful delivery.
Number of Bits per Word - Number of Bits per Word refers to the number of binary bits contained in a single word of data transmitted over the wireless channel.
Expected One Transmission - Expected One Transmission typically refers to the desired outcome or expectation of successfully transmitting data or information in a wireless network using a single transmission attempt.
STEP 1: Convert Input(s) to Base Unit
Number of Word Message Consist: 19 --> No Conversion Required
Information Bits: 3 --> No Conversion Required
Header Bits: 9 --> No Conversion Required
Expected Number of Transmission: 4 --> No Conversion Required
Number of Bits per Word: 12 --> No Conversion Required
Expected One Transmission: 3.3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Rs = (Nwd*L)/(H*En+Bwd*E1*Nwd) --> (19*3)/(9*4+12*3.3*19)
Evaluating ... ...
Rs = 0.0722983257229833
STEP 3: Convert Result to Output's Unit
0.0722983257229833 --> No Conversion Required
FINAL ANSWER
0.0722983257229833 0.072298 <-- Selective Retransmission

Level Crossing Rate
​ Go Level Crossing Rate = (sqrt(2*pi))*Maximum Doppler Shift*Normalized RMS Value*e^(-(Normalized RMS Value^2))
Mobile Radio Distance
​ Go Transmitter Reciever Distance = (Path Loss Coefficient/Mobile Reciever Carrier Power)^(1/4)
Mobile Radio Signal
​ Go Mobile Radio Signal = Long Term Fading*Multipath Fading
Multipath Fading
​ Go Multipath Fading = Mobile Radio Signal/Long Term Fading

Selective Retransmission Formula

Selective Retransmission = (Number of Word Message Consist*Information Bits)/(Header Bits*Expected Number of Transmission+Number of Bits per Word*Expected One Transmission*Number of Word Message Consist)
Rs = (Nwd*L)/(H*En+Bwd*E1*Nwd)

How much is a bit of information?

The word "bit" is short for "binary digit." A bit is the smallest piece of computer information. byte: Most computers use combinations of eight bits, called bytes, to represent one character of data. For example, the word "cat" has three characters, and it would be represented by three bytes.

How to Calculate Selective Retransmission?

Selective Retransmission calculator uses Selective Retransmission = (Number of Word Message Consist*Information Bits)/(Header Bits*Expected Number of Transmission+Number of Bits per Word*Expected One Transmission*Number of Word Message Consist) to calculate the Selective Retransmission, The Selective Retransmission formula is defined as Selective repeat protocol, also called Selective Repeat ARQ (Automatic Repeat Request), is a data link layer protocol that uses the sliding window method for reliable delivery of data frames. Here, only the erroneous or lost frames are retransmitted, while the good frames are received and buffered. Selective Retransmission is denoted by Rs symbol.

How to calculate Selective Retransmission using this online calculator? To use this online calculator for Selective Retransmission, enter Number of Word Message Consist (Nwd), Information Bits (L), Header Bits (H), Expected Number of Transmission (En), Number of Bits per Word (Bwd) & Expected One Transmission (E1) and hit the calculate button. Here is how the Selective Retransmission calculation can be explained with given input values -> 0.072298 = (19*3)/(9*4+12*3.3*19).
