State variables | |
|---|---|
τ i (t) | Transmission probability of the node in the class-i at the time t |
p i s(t) | Success probability of the transmission of a node in the class-i at the time t |
p i (t) | Probability that a node in the class-i transmits simultaneously with other node at the time t |
p i capture(t) | Probability that the transmission of the node in class-i is successfully received when its transmissions simultaneously occurs with other node |
T i (t) | Waiting time of the node in class-i, i.e., number of virtual slots between two consecutive successful transmissions |
W i (t) | CW size of the node in class i at the time t |
System parameters | |
M | Number of classes in the system |
N i | Number of nodes in the class i |
N | Total number of nodes, i.e., N = N1 + N2 + · · · + N M |
Control parameters | |
α and β | Control parameters |
T ref | Desired waiting time, i.e., target waiting time |
