Table 1 Notations used in the Markov model
From: Performance evaluation of the V2I fair access with a finite retry limit
Notation | Definition |
|---|---|
i | The number of the retransmission |
k | The value of a counter |
b(i, k) | Stationary probability of states with a packet waiting to transmit when the number of the retransmission is i and the value of the counter is k |
b(i, k) e | Stationary probability of states without packets waiting to transmit when the number of the retransmission is i and the value of the counter is k |
\( {W}_m^i \) | Window size when the number of the retransmission is i |
m | The maximum number of the retransmission beyond which the window would not be doubled |
m + f | Retry limit |
q | Probability that a node has a packet prepared to transmit |
p | Collision probability |
P idle | Probability that the channel is sensed idle |
Ï„ | Transmission probability |
