Applications of Data Grouping for Effective MobilityDarrell D. E. LongThe problem of reducing a mobile computer's communication and powerrequirements will be investigated. Specifically, this research will addressboth issues through improved storage management. Based on successes withautomated data grouping and predictive power conservation, research will beconducted into improved data hoarding and disk power management techniques.Effective grouping of data will make it possible to improve the automationof mobile file hoarding, and decrease the effects of network latency anddisconnections on the mobile user. Similarly, through the grouping andretrieval of related on-disk data, it is possible to improve disk powermanagement beyond the theoretical limits of any previously attempted scheme.This will be done by actively modifying the access sequence to minimizepower requirements. Through transformation of data access workloads, thisnovel approach reshapes disk idle times to effectively increase the amountof time a disk can be spun down. Improving the battery life of mobilecomputing devices is critical to their usefulness, and such power efficiencyis clearly an environmentally responsible goal. This research will establishthe effectiveness of on-line data grouping techniques to increase the amountof data accessed per operation, while simultaneously reducing the totalnumber of disk operations.

数据分组用于有效的MobilityDarrell D. E.减少移动计算机的通信和功率报价的问题。具体而言，这项研究将通过改进的存储管理解决问题。基于研究的数据分组和预测能力保护的成功，研究将进行改进的数据ho积和磁盘电源管理技术。有效的数据分组将使改善移动文件ho积自动化的自动化，并降低网络延迟对移动用户的影响。同样，通过相关盘数据相关数据的分组和电击，可以超越任何先前尝试的方案的理论限制来改善磁盘驱动管理。这将通过积极修改最小值要求的访问顺序来完成。通过转换数据访问工作负载，此Novel方法可以重塑磁盘空闲时间，以有效地增加磁盘可以旋转的时间。改善动机计算设备的电池寿命对其有用性至关重要，而且这种功率效率显然是对环境负责的目标。这项研究将确定在线数据分组技术的有效性，以增加每个操作访问的数据的量，同时减少磁盘操作的总数。
