NeTS-NBD: Finding Mobile Information in Wireless Networks

这个项目提出了新的算法和组合优化研究，目标是开发高效的搜索引擎，使用移动目录的新范例在当前和未来的无线网络中定位移动信息(移动)。移动目录由反映各种条件下移动位置的特定和统计知识的简档组成。当网络搜索手机时，它会应用适当的配置文件。简档可以由网络基于过去的历史创建，也可以由用户给出。在任何一种情况下，都将探讨手机隐私级别作为搜索效率的权衡问题。该项目的目标是为给定的配置文件设计有效的搜索策略，优化资源消耗，并构建最能预测移动设备下落的配置文件，同时保持一些隐私要求。无线网络中移动信息(或用户)的位置管理的综合解决方案是此类网络的主要挑战之一，系统的进步不足以满足未来的需求，因此非常需要改进算法和实现。能够回答复杂查询以查找移动信息的无线系统将在紧急与和平时期使网络及其用户受益。当在哪里找到查询的答案存在一些不确定性时，开发的搜索技术可能会对一些互联网搜索引擎有利。该项目强调隐私保护问题，这是移动用户最关心的问题。

This project proposes novel algorithmic and combinatorial optimization research with the goal of developing efficient search engines for locating mobile information (mobiles) in current and future wireless networks using a new paradigm of mobile directories. The mobile directories are composed of profiles that reflect certain and statistical knowledge about locations of mobiles under various conditions. When the network searches for a mobile, it applies the appropriate profile. The profiles could either be created by the network based on past history or be given by the users. In either case, the issue of mobiles' privacy level as a tradeoff for search efficiency will be explored. The project goals are to design efficient search strategies for given profiles, optimize the consumption of resources, and construct profiles that best predict the whereabouts of mobiles while maintaining some privacy requirements.A comprehensive solution for location management of mobile information (or users) in wireless networks is one of the major challenges for such networks for which advances in systems will not suffice to accommodate future demands and there will be a great need for advances in algorithms and implementations. Wireless systems that can answer sophisticated queries to find mobile information will benefit the networks and their users in times of emergency and peace. The developed search techniques can be beneficial to some Internet search engines when there is some uncertainty about where to find answers to queries. The project puts emphasis on the privacy preserving issue which is a paramount concern for mobile users.
