This Small Business Innovation Research Phase I project designs and develops an adaptive remote-data access system for wireless handheld devices. The key innovations in the project include adaptive data compression and adaptive partitioning techniques to save network bandwidth and battery consumption. The central concept is the ability to adapt to the changing wireless network environment and to different types of data. The proposed techniques go beyond existing bandwidth-saving techniques such as nonadaptive compression and "diff"-based data synchronization. A research prototype will be built for extensive experimentation in order to measure the effectiveness of the proposed technique for the saving of network bandwidth and battery consumption. This prototype will integrate heterogeneous systems, runtime systems, and compiler techniques. Commercial Applications of Research: The success of this research will lead to a software product which provides users of wireless handheld devices with secure, convenient, and cost-effective access to the data (and associated applications) located on their stationary computer systems, such as desktop machines and servers. This product can be used by both business and individual users for various functionalities which require to access data stored on the main computer systems in the form of text, graphics, photographs, data images, speeches, sound, and so on. The adaptive features of the system fulfill the need of remote-centric workforce to access host-based data and applications from anywhere at any time over wireless connections in a highly cost-effective way.

这个小型企业创新研究第一阶段项目设计和开发一个自适应远程数据访问系统的无线手持设备。该项目的关键创新包括自适应数据压缩和自适应分区技术，以节省网络带宽和电池消耗。核心概念是能够适应不断变化的无线网络环境和不同类型的数据。所提出的技术超越了现有的带宽节省技术，如非自适应压缩和“差异”为基础的数据同步。将建立一个研究原型进行广泛的实验，以衡量所提出的技术在节省网络带宽和电池消耗方面的有效性。该原型将集成异构系统、运行时系统和编译器技术。研究的商业应用：这项研究的成功将导致一个软件产品，为无线手持设备的用户提供安全，方便和具有成本效益的访问数据（和相关的应用程序）位于他们的固定计算机系统，如台式机和服务器。该产品可用于商业和个人用户的各种功能，这些功能需要访问以文本，图形，照片，数据图像，语音，声音，该系统的自适应功能满足了以远程为中心的工作人员的需求，即通过无线连接随时随地访问基于主机的数据和应用程序，有效的方式。
