Adaptive fault tolerant mobile agent system for information retrieval

Abstract

The advent of large wide area networks, such as the Internet has caused a vast increase both in the availability and the number of information sources The ability to retrieve information from these distributed and heterogeneous resources offers great promise for obtaining and sharing diverse information conveniently The drawbacks of most of the client server based information retrieval techniques are the need for a continuous newlineconnection overhead in bulk data transfer robustness and server workload Mobile agents that are distributed and flexible are especially useful to solve these problems in distributed information retrieval During its travel in the event of information retrieval a mobile agent may get blocked or failed due to various issues This research work identifies some of the issues such as dynamic travel plan accommodation security and reliable execution Building a mobile agent system that incorporates all these requirements ultimately saves time reduces the network load and ensures the successful newlinemigration of the mobile agent Dynamic information retrieval requires a careful selection of the nodes on the fly that are optimal to the user Selecting an optimal node based on the available approaches restricts a mobile agent to migrate only to the adjacent node newline
