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，为移动的P2P数据库中的查询处理提供支持。 其通过以下方式实现该目标：1）开发用于数据项的排序函数，该排序函数结合了诸如移动的P2P系统中的数据项的供应、其在系统中的需求、数据项的大小以及其可靠性的因素; 2）使得查询处理系统能够在蜂窝基础设施可用时利用蜂窝基础设施;以及3）开发激励机制，该激励机制将激励用户参与查询处理系统，即使当他们没有个人查询要处理时。研究结果将能够发现本地的，可能是临时的，资源在许多应用领域，包括社交网络，交通，移动的电子商务，应急响应和国土安全。该项目支持博士学位。学生从事移动的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/aboxu/mobidik）传播。
