对推送系统的研究自然集中在改善客户服务时间上。然而，在许多情况下，选择推式逻辑和拉式逻辑的决定性因素是中央基础设施成本较低。自适应推送系统将这种情况带入下一步，要求每隔几秒或几分钟集中计算最佳广播时间表，由相对便宜的服务器硬件执行。针对引入成本感知的无线广播系统，提出了快速优化-内存节省（FOMC）方法。该方法的目标是降低中央服务器所需的计算能力和内存，使其可以用主流硬件实现，并纳入分钟级自适应系统。为了证明考虑成本的重要性，将 FOMC 与经典且有影响力的广播磁盘方法进行了比较。虽然 FOMC 成功地要求合理的计算能力和最小的内存，但广播磁盘方法在实践中根本无法实现。最后，在最大限度地减少最佳广播参数的扫描时间的第一次努力中，正在通过专门采用的多元说明技术来研究它们与广播数据项总数的关系，并且观察到它是非线性的。
Research on push systems has naturally focused on improving the client serving time. However, in many cases the determinant factor for choosing between push and pull logic is the low central infrastructure cost. Adaptive push systems take this condition to the next step, requiring the central calculation of optimal broadcast schedules every few seconds or minutes, performed by relatively inexpensive server hardware. Aiming at introducing cost-aware wireless broadcasting systems, the Fast Optimization - Memory Conserving (FOMC) method is presented. The goal of the proposed method is to reduce the required computational power and memory of the central server, to the point that it can be implemented with mainstream hardware, and be incorporated to minute-scale adaptive systems. In order to demonstrate the importance of taking cost into account, FOMC is compared with the classical and influential Broadcast Disks method. While FOMC succeeds in requiring reasonable computational power and minimal memory, the Broadcast Disks method is rendered merely unrealizable in practice. Finally, in a first effort to minimize the scanning time for optimal broadcasting parameters, their relation with the total number broadcasted data items is being studied through a specially adapted multivariate illustration technique, and it is observed to be non-linear.
