论文摘要
提供了对线性功率控制策略的全面分析，其中包括众所周知的贪婪政策和固定分数政策作为特殊情况。介绍了给定电池容量$ c $和平均容量比$ p $以及其$ c $ - 宇宙版本的最大最佳线性政策的概念。除其他外，固定分数策略是$ c $ - 宇宙添加剂最佳的，但不是$ c $ - 宇宙倍增因素最佳。针对某些能源到达分布的家族建立了对电池容量阈值的紧密半宇宙范围。
A comprehensive analysis of linear power control polices, which include the well-known greedy policy and fixed fraction policy as special cases, is provided. The notions of maximin optimal linear policy for given battery capacity $c$ and mean-to-capacity ratio $p$ as well as its $c$-universal versions are introduced. It is shown, among others, that the fixed fraction policy is $c$-universal additive-gap optimal but not $c$-universal multiplicative-factor optimal. Tight semi-universal bounds on the battery-capacity-threshold for the optimality of the greedy policy are established for certain families of energy arrival distributions.
