Group Communication Based Approach for Reliable Mobile Agent in Information Retrieval Applications

Mobile agents have attracted considerable interest in recent years. Mobile agents travel through servers to perform their programs. Maintaining mobile agent availability in the presence of agent server’s crash, during their travel, is a challenging issue, since, developers normally have no control over remote agent servers. In the context of mobile agents, fault tolerance is crucial to enable the integration of mobile agent technology into today’s business applications. In multi mobile agent deployment, communication among mobile agents is another aspect to concentrate. When it ensures the aliveness of other agents, agent reliability and data availability, there is a need to locate agents to implement the communication aspect. Considering the merits of the existing work, this paper proposes an attempt to improve the agent survivability in the aspect of multiple agent deployment and communication among them for information sharing.
