A mobile agent-based distributed information retrieval system. – F.U. Ogban and U.C.Udoh
Information retrieval techniques have to face both the growing amount of data to be processed and the “natural” distribution of these data over the network. Various technologies and solutions have been developed to handle this situation, including the Mobile Agent technology. A mobile agent is an executing program that can migrate during execution from machine to machine in a heterogeneous network. On each machine, the agent interacts with the local resources to accomplish its task. Mobile Agents are particularly attractive in distributed information retrieval applications for several reasons, including reduction of network load and server access time delay and achievement of higher error tolerance and security. Moreover, Mobile Agents can offer a flexible, versatile, and powerful framework for efficiently
developing distributed applications on the Internet. In this research work, a mobile agent for Retrieving Exam results in a distributed database system has been described. The University of Calabar was used as a case study. In the system, two types of sites are used. There are Student Affairs Site and Department Site. The system has been developed using the java programming and the mobile agents have been implemented using the IBM’s Aglet Software Development Kit (ASDK).
