Modeling Slotted Aloha as a Stochastic Game with Random Discrete Power Selection Algorithms

Figure 2

Stability of slotted aloha with random power selection algorithms: Probability of success transmission versus backlogged packets 𝑛 for all the schemes. We consider 𝛾_th=10 dB, transmit powers 𝒫=[1,5,25,125,625]mW, arrival probability 𝑞_𝑎=0.01 and different retransmission probabilities (aggressiveness levels) 𝑞_𝑟=0.1 (sub-figure a), 𝑞_𝑟=0.25 (sub-figure b) and 𝑞_𝑟=0.5 (sub-figure c).
