Abstract—In recent years, developing processing techniques for spatio-temporal databases is a very hot topic. There are many real-life applications related to spatio-temporal queries, such as geographic information, traffic monitoring system, and mobile information system. In this paper, we focus on how to process the range query in jail management. Different from the previous research, the moving objects are the convicts and the jail guards in jail management. Moreover, the positioning technique used in jail management is not the GPS technique, but is the sensor network technique. This results in a greater positioning error. The jail management system developed in this paper tries to manage the convicts and the guards with uncertain location information. With the location information, we will design efficient algorithm to process the range query on the convicts and the jail guards. Benefiting from the jail management system, we can efficiently manage the convicts and the quards so as to provide useful information to the jail manager.
