一种资源受限的系统通过请求受限于随机传输延迟的有限数量的更新来监视信息源。一个先验的固定的更新请求政策，以尽量减少多项式惩罚函数的年龄在任意时间范围内的信息。部分更新，压缩更新，减少传输和信息内容，在所提出的模型中，所示的招致独立的压缩的年龄惩罚。有限的视野，有更好的表现在二阶统计量相对于无限的视野。
A resource-constrained system monitors a source of information by requesting a finite number of updates subject to random transmission delays. An a priori fixed update request policy is shown to minimize a polynomial penalty function of the age of information over arbitrary time horizons. Partial updates, compressed updates with reduced transmission and information content, in the presented model are shown to incur an age penalty independent of the compression. Finite horizons are shown to have better performance in terms of second order statistic relative to infinite horizons.
