研究了时隙Aloha系统中功率微分下重传概率的分布式选择问题。我们考虑随机传输功率和进一步研究的优先级（通过功率控制）的作用，无论是新到达的数据包或积压的。我们研究了合作团队问题，其中一个共同的目标是联合优化，以及非合作博弈问题。我们表明，新提出的方案不仅大大提高了平均性能，而且在某些情况下还能够消除时隙Aloha的双稳态性质。
We study distributed choice of retransmission probabilities in slotted Aloha under power differentiation. We consider random transmission powers and further study the role of priorities (through power control) given either to new arriving packets or to backlogged ones. We study both the cooperative team problem in which a common objective is jointly optimized as well as the noncooperative game problem. We show that the new proposed schemes not only improve the average performances considerably but are also able in some cases to eliminate the bi-stable nature of the slotted Aloha.
