SGER: Feasibility of Decentralized Search in Mobile P2P Databases

该项目的目标是通过使用数据项存储转发的范例，为移动P2P数据库中的查询处理提供支持。为了实现这一目标，本文采用了以下方法：1)开发了一个数据项排序函数，该函数包含了移动P2P系统中数据项的供给、系统中数据项的需求、数据项的大小和可靠性等因素；2)当蜂窝基础设施可用时，使查询处理系统能够利用该基础设施；3)开发一种激励机制，即使用户没有个人查询需要处理，也能激励他们参与查询处理系统。研究结果将有助于在许多应用领域（包括社交网络、交通运输、移动电子商务、应急响应和国土安全）中发现本地（可能是临时的）资源。该项目支持一名博士生在移动P2P数据库领域进行研究。本研究的出版物、技术报告、软件和实验数据将通过项目网站（http://www.cs.uic.edu/~boxu/mobidik）发布。

The goal of this project is to provide support for query processing in a mobile P2P database by using a paradigm of data-item store-and-forward. It achieves this goal by 1) developing a ranking function for data-items that incorporates factors such as the supply of a data item in the mobile P2P system, its demand in the system, the size of the data-item, and its reliability; 2) enabling the query processing system to take advantage of a cellular infrastructure when such is available; and 3) developing an incentive mechanism that will motivate users to participate in the query processing system even when they do not have a personal query to process. The research results will enable discovery of local, and possibly temporary, resources in many application domains, including social networks, transportation, mobile electronic commerce, emergency response, and homeland security. This project supports a Ph.D. student to pursue research in the area of mobile P2P databases. Publications, technical reports, software, and experimental data from this research will be disseminated via the project web site(http://www.cs.uic.edu/~boxu/mobidik).
