Applying Mobile Agent in Criminal Information Retrieval System

Mobile Agent is a type of software system which acts “intelligently” on one’s behalf with the feature of autonomy, learning ability and most importantly mobility. Therefore, Mobile Agent technology is suitable for collecting data from police stations on behalf of police officers. In this article, Mobile Agent will be addressed as tools for retrieving Criminal record of the offenders. The offenders’ biography is an important data for police officers in deciding criminal case. So, Mobile Agent technology is used for transferring this data between police stations. At first, the authorized police officer from any police station can search for the desired biography of an offender in its own database. If it is not found, the officer  can search it at remote sites by using Query Agent (QA).To get that biography, Query Agent (QA) migrates from a host station to remote stations, negotiates with Database Agent (DA) in there, and replies the required information to Police Officer Agent (POA). By implementing this system, several advantages such as time saving, reduce paper work, flexible structuring, dynamic content delivery and less manpower requirement can be achieved. Moreover, it can upgrade the traditional information retrieval system to e-government system. This paper describes the project architecture and its implementation that is based on IBM’s Aglets Workbench.
