Abstract
The mobile agent systems are well suited for certain types of real
world applications such as e-commerce and distributed transactions. However,
this technology is not being used by many applications. This is due to the
lack of infrastructures and methodologies that address fault tolerance and
transactions. The basic requirements for fault-tolerant transactional mobile
agent are: 1) non-blocking (i.e., a single failure does not prevent progress of the
mobile agent execution); 2) exactly-once (i.e., multiple executions of the agent
are prevented); 3) the execution atomicity (i.e., all tasks are committed or none
at all). In this paper, we propose a mechanism for providing fault-tolerance
capability based on the mobile agent replication and the backward process. The
failure detection is not perfect. The replication may results in multiple
executions of the agent. So, we defined a technique that detects multiple
executions and allows only one agent to go on while the others are stopped. To
ensure the execution atomicity of the distributed transaction we used a commit
at destination approach.
