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).

该项目的目标是通过使用数据项存储和转发的范例为移动 P2P 数据库中的查询处理提供支持。 它通过以下方式实现这一目标：1）开发数据项的排序功能，该功能结合了移动P2P系统中数据项的供应、系统中的需求、数据项的大小及其可靠性等因素； 2) 使查询处理系统能够利用可用的蜂窝基础设施； 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。研究结果将使人们能够在许多应用领域发现本地的、可能是临时的资源，包括社交网络、交通、移动电子商务、应急响应和国土安全。该项目支持博士学位。学生从事移动 P2P 数据库领域的研究。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）传播。
