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 t h = 1 0 dB, transmit powers 𝒫 = [ 1 , 5 , 2 5 , 1 2 5 , 6 2 5 ] m W , arrival probability 𝑞 𝑎 = 0 . 0 1 and different retransmission probabilities (aggressiveness levels) 𝑞 𝑟 = 0 . 1 (sub-figure a), 𝑞 𝑟 = 0 . 2 5 (sub-figure b) and 𝑞 𝑟 = 0 . 5 (sub-figure c).
