Slotted ALOHA Game for Medium Access Control in Satellite Networks

摘要

In this paper, slotted ALOHA (SA) game is proposed for medium access control in satellite networks. The SA game studies the transmission probabilities of a group of non-cooperative satellite terminals (STs) sharing a channel to transmit via the SA protocol. We consider a payoff function based on a probability of successful transmission and derive the mixed strategy Nash equilibrium (NE) with a closed form. Simulation results show that the SA game can support a large amount of STs, and it can keep at its peak throughput even at very high traffic loads and exhibits a low access delay and energy consumption.
