Location tracking in mobile agents system using forward and backward pointers

Mobile agents are the intelligent programs that act autonomously on behalf of a user and can migrate from one host to another host in a network in order to satisfy the requests made by their clients. The critical problem in managing a mobile agent system is to track the location of the agents. Communication with a mobile agent incorporates the ability to locate it. This paper surveys the state-of-the-art mobile agent location monitoring techniques, proposed by various authors and also we propose a novel approach for tracking the location of the agent in its itinerary by integrating footprints to centralized server approach, using forward and backward pointers. The results show better performance in case where a centralized server gets destroyed due to some fault and looses all its data of various locations, also to maintain the hierarchy of visited hosts we add the concept of forward and backward pointers.
