Abstract

A transactional agent is a mobile agent to manipulate objects distributed on computers. A transactional agent can change a schedule to visit computers if some target computer is faulty. In order to reduce the communication overhead, a transactional agent is composed of routing and manipulation subagents. A routing subagent makes a decision on what computer to visit in presence of faults of computers. On arrival at the computer, the routing subagent loads classes of a manipulation subagent to locally manipulate objects. We evaluate the transactional agent model in terms of access time compared with the traditional client-server model.
