Fault-tolerant execution of mobile agents

Abstract
In this paper, we will address the list of problems that have to be solved in mobile agent systems and we will present a set of fault-tolerance techniques that can increase the robustness of agent-based applications without introducing a high performance overhead. The framework includes a set of schemes for failure detection, checkpointing and restart, software rejuvenation, a resource-aware atomic migration protocol, a reconfigurable itinerary, a protocol that avoids agents to get caught in node failures and a simple scheme to deal with network partitions. At the end, we will present some performance results that show the effectiveness of these fault-tolerance techniques.
