项目摘要

This research investigates a new architecture designed to providedata to wireless users using a broadcast technique. The objective of this research is to develop schemes for implementing the concept ``DAta in your space (DAYS)" which combines broadcasting (push) and traditional querying (pull) techniques into one global wireless approach. In this scheme the data broadcasters (special servers) will continuouslybroadcast (push) requested data to a set of ``dedicated" wirelesschannels, which will be captured by clients (users of the data) atany time and at any place. The space will thus be used aspersistent storage for all mobile as well as static devices. A universal wireless broadcast approach requires that mobile users be able to find and use the right broadcast information. Some of the questions to mbe addressed include:1. How can the mobile user know which channel has the correct data?2. How is data to be assigned to channels?3. What techniques can be used to effectively determine the best contents of each channel given many mobile users?4. Without explicit user queries, how can the mobile user be assured that the needed data is being broadcast?5. How can the mobile user be assured that the needed data moves with him?These issues have to be examined on a global scale.

本研究探讨了一种新的架构，旨在提供数据的无线用户使用广播技术。这项研究的目的是制定实施”你的空间数据“概念的计划，该概念将广播（推）和传统查询（拉）技术结合成一种全球无线方法。在该方案中，数据广播器（专用服务器）将连续广播（推）请求的数据到一组“专用”无线信道，这些信道将被客户端（数据的用户）在任何时间和任何地点捕获。因此，该空间将用作所有移动的以及静态设备的永久存储。通用无线广播方法要求移动的用户能够找到并使用正确的广播信息。一些需要解决的问题包括：1。移动的用户如何知道哪个信道具有正确的数据？2. 如何将数据分配给通道？3. 在有许多移动的用户的情况下，可以使用什么技术来有效地确定每个频道的最佳内容？4. 如果没有明确的用户查询，移动的用户如何能够确信所需的数据正在被广播？5.如何才能确保移动的用户所需的数据与他一起移动？必须在全球范围内审查这些问题。
